GFRG New Construction – Low Cost

Glass fiber reinforced gypsum(GFRG) wall panel is made essentially of gypsum plaster reinforced
with glass fibers which when filled with reinforced concrete in an appropriate proportion becomes strong enough to act as a load-bearing and shear wall. The panels are hollow and can be used as load-bearing walls. The hollow cores inside the walls can be filled within-situplain or reinforced
concrete.Glass fiber reinforced gypsum (GFRG) panel or Rapid wall is a modern building element
for mass-scale construction of houses in a very short span of time.
GFRG panels can even resist the lateral loads due to earthquakes and wind. Not only the walls, but the roofs, floors, sunshades and the boundary walls can be also made using GFRG panels. Looking at
its success and innumerable advantages, the technology spread like wildfire and is being adopted
heavily throughout the construction industry.
Applications of GFRG Panels

  1. As a light-weight bearing wall
  2. As high-capacity vertical and shear load-bearing wall
  3. As partition wall
  4. As roof slabs/horizontal floor
  5. As compound wall/Security wall
  6. As pitched roofing
  7. As cladding in industrial structures
    Limitations of GFRG Panels
  8. The panels are required to be handled with extreme care and specific machinery is
    needed for their movements.
  9. The panels cannot be used for wall with circular or higher curvature.
  10. The panels need to be neatly stacked in order to avoid abrasion.
  11. The clear span is limited to 5m for residential buildings.
     What are the other benefits of GFRG panels?
    GFRG panels are environment-friendly, make construction faster, materials like sand and cement are required in less quantity. Gives more carpet area, long-lasting, fireproof soundproof, it reduces the overall cost by at least 20% and keeps room temperature cooler than that of conventional buildings.
     How much does a single GFRG panel cost?
    Single GFRG panel cost around rupees thousand with GST it will cost around rs1120 per
    square meter.

In Bangalore Tavara Mines and Minerals is one of the best manufactures of m sand in Bangalore.

To know more about the manufacturing of m sand 

Why use M Sand for constructions.

The demand for natural sand in the market is very high because the government has banned the digging of natural sands from the river bend.

M Sand Vs River Sand
M Sand Vs River Sand

Due to the demand in the market, the price of natural sand is very high compared to m-sand. Natural sand is 4 times costly than m sand.

Advantages of M Sand

  • Cost Efficiency
  • Eco-Friendly
  • Stronger than river sand when it is manufactured properly
  • It’s free of Organic Impurities
  • Workability of concrete
  • Lesser construction defects

How to find the best quality of M Sand.

All the M Sands are not good quality m sands. It should be manufactured properly crushed and washed in a plant.

Some people in Bangalore sell Crushed rock fines as an M Sand but Crushed rock fines look similar to m sand but it is not m sand. It is not good for Construction

M Sand Site Testing
M Sand Site Testing

If the M Sand is not washed properly in the plant, the impurities will not be removed properly which is bad for construction. Always buy an M Sand form a verified Plant which is ISO Certified. Here are Tips to check the quality of M Sand.

M Sand Price in Bangalore

The average Concrete M Sand price in Bangalore can vary between Rs. 635 – Rs. 1140/ Tons Including the Trasport charges. The Price May Differ Depending upon the Area and Distance. To Know the M Sand Exact price Click Here .

Site Test for M Sand

Sand is a basic raw material used in the construction industries. It is fine aggregate having the particle size between 150 microns and 4.75 mm. Silt content is a super fine material which is less than 150 microns / 0.15 mm in Size. The slit content should not be more than 6% of the total volume of the sand.

Tests for finding quality of sand on site

Excessive clay / Silt

Presence of clay in Sand makes the sand cohesive, the good quality of sand should have less percentage of clay in it.

Presence of excessive clay can be determined in two ways

  1. For the testing, the presence of clay in the sand, take a glassful of water and add some sand to it. Shake it vigorously and allow the sand to settle. Check whether an apparent layer is formed on the sand. Good quality of sand should have less than 8% of clay in it.
  2. Hold some dry sand and drop it. If the Sand adheres to your palm, then it has Clay.

Presence of Organic Impurities in Sand

For detecting the presence of Organic impurities in fine aggregate. Take a Sample of sand and add it in Sodium Hydroxide [NaOH] Solution, Stir the solution for few minutes, if the color of solution changes to brown, then the sand has organic impurities which are not suitable for construction. Good quality of sand shows a lighter color when it is mixed with NaOH solution.

Presence of Excessive moisture content / Bulking of Sand

Presence of excessive moisture content in sand causes increases in the volume of sand. Fine Aggregate Which contains more than 5% of moisture content in its volume is not suitable for construction purposes. For accurate conclusions, fineness modulus test and salt content by weight are suggested for large projects.

Quarry Dust VS M Sand – Are You Using right sand for your constructions?

Let us first understand the meaning of quarry dust and m-sand individually.

Quarry dust is a by-product of the crushing process which is a concentrated material to use as aggregates for concreting purpose, especially as fine aggregates. In quarrying activities, the rock has been crushed into various sizes; during the process the dust generated is called quarry dust and it is formed as waste.

Manufactured sand (M-Sand) is a substitute of river sand for concrete construction. Manufactured sand is produced from hard granite stone by crushing. Manufactured sand is an alternative for river sand. Due to the fast growing construction industry, the demand for sand has increased tremendously, causing deficiency of suitable river sand in most part of the word.

The contrary between the two can be understood in the following fields:

Appearance and formation :

  • Original M Sand is free from an elongated and flaky particle since it is shaped cubically using VSI shaping machine. The cubically shaped particles give high strength and long life to concrete.
  • Quarry dust is an elongated and flaky particle. It is fractured dust of Jaw Crusher.  A waste product in the production process of stone crusher.

Manufacturing :

  • Original M Sand is manufactured strictly adhering to IS 383 (1970) zone II grading. Perfect grading and cubical shape of M Sand provides 10-15% more compressive strength for concrete and 25-30% more strength for masonry works compared to crusher dust.
  • Quarry dust has no controlled manufacturing process as it is the bi-product of stone crusher. Does not adhere to IS 383 – 1970 or any other standards

Quality and Strength:

  • Original M Sand has minus 150 micron less than 10% and minus 45 micron less than 2% only. This helps the concrete to maintain water absorption rate of concrete less than 2% which helps to produce concrete of consistent quality.
  • Quarry dust has lesser concrete strength and lower durability. Not recommended for use in concrete or masonry works.

Quality of outcome:

  • Original M Sand is graded with precession by removing the microfine correctly and thus it has higher ‘Finess Modules Index’ compared to river sand and crusher dust. This gives good workability for concrete and masonry that help in easy and quick construction.
  • In case of Quarry dust, in order not to compromise the strength of building during construction, the dust comes handy as an equal substitute without threat to quality at the same time rendering good strength to constructions.

Cost

  • Quarry dust come at cheaper cost and lesser pressure on market demand for sand. Partial replacement of sand with this dust will make good concrete that is well desired in residential construction. The final product is strong bricks, slabs or tiles that are produced at lower cost compare to using sand.
  • Original M Sand has two grades for concreting and plastering. This saves you the work of filtering the sand. Besides, as there is no loss of sand, you can save money on it.

How manufactured-sand help reduce indiscriminate sand mining and saving ecosystems

River beds

There is an urgent need to protect the environment by protecting the river beds, but the construction industry needs sand. Manufactured sand is the solution to this problem. The manufactured sand industry has potential in the region that boasts of several blue metal quarries. Blue metal is the raw material for manufactured sand. Listing out the environmental degradation caused by exploiting river sand, 18 lakh wells in the southern region turned useless since groundwater level dipped alarmingly as river sand, the natural aquifer, was depleted from rivers.

Water table, which was at 50 ft or so, fell to 600 ft in Madurai. There is no water even for agriculture purposes. The government agencies should start taking up construction activities using manufactured sand in place of river sand. Manufactured sand is superior to river sand since the former has better grip in concrete and free of silt and organic impurities. Many big projects have been carried out with the use of the manufactured sand. Public should be sensitised about using it in place of river sand.

M Sand (Manufacture Sand) and its Advantages

What is manufactured-sand, or artificial, or engineered-sand, as it is described? M-sand is produced by passing boulders and stones through a series of jaw and cone crushers for size reduction and then fed into vertical shaft impact (VSI) crushers where they are pulverized further to the size of sand. The VSIs crush them to cubical and angular particles. In certain markets, this is flogged off as m-sand; it’s a masquerade. This process is incomplete From the VSI stage, the sand has to further go through a process of elaborate washing to remove dust and flaky particles Washing in a hydro cyclone process is apparently critical to the entire sand manufacturing process as it effectively removes excess ultrafine of minus 75 microns from the feed material. Ultrafine can be detrimental to the making of concrete.

Manish Bhartia, MD of CDE Asia, has introduced an array of high-performance crushers and washers in India over the past few years. He says the sand thus washed and dewatered is impurity free and Ready-Mix Concrete (RMC) ready. His manufacturing unit in Kolkata is jointly promoted by CDE Global of the UK and the Bhartia family.

Apparently these machines with washers that also help in dousing dust at production sites are a class apart from the crude equipment used at stone quarries.
That the concept of manufactured-sand is gaining traction can be gauged from the fact that, since 2007, when Bhatia began operations, he has been involved in over 60 crushing projects. One of his anchor clients is the Bhopal-based Dilip Buildcon which operates a cluster of 15 plants across the region.

Bhartia estimates that the collective output of msand across all plants would be merely 10 million tonnes per annum (Mtpa). “Of this barely 25 per cent of manufactured-sand produced comes into the open market,” he says. The rest are consumed in-house by large developers and RMC units. The demand for sand is estimated at 500 Mtpa. The nascent industry is just about scratching the surface.

While m-sand gains traction in the market, the idea of abolishing the stone quarry bit in the system seems quite enticing. This is precisely what IL&FS Environment, a subsidiary of IL&FS, one of India’s leading development and finance companies, is doing.

IL&FS is propagating the use of construction and demolition (C&D) waste for the production of m-sand and other aggregates. It is operating India’s first C&D waste recycling facility in Delhi with a capacity of 2000 TPD.

C&D waste is a huge problem in our metro cities. Delhi alone generates over 5,000 tonnes of C&D waste every day. Where does this waste go? It is surreptitiously dumped along roadsides or in water bodies, and in Mumbai, into stretches of mangroves along the seashore. The recent flooding of Chennai can also be partly attributed to this trend.

In Navi Mumbai, if construction debris is cleared out from all the stretches it is dumped in, the city can recover land worth Rs 6,000 crore.

L&FS Environment claims that its C&D waste management facility has helped save over 25 acres of land valued at Rs 250 crore. Its plant has processed over 20 lakh tonnes of C&D waste since it started operations and has recovered/recycled 95 per cent of the incoming waste. Enthused by the results of the pilot C&D recycling plant, several agencies including the PWD, Delhi Metro and municipal bodies have commissioned IL&FS Environment to setup and operate similar plants.

The only impediment to the adoption of recycled-sand (r-sand) has been the absence of clear government guidelines on the usage of recycled products as in the US or the EU. This has been addressed to an extent now: the Delhi government has issued an advisory to all departments to use a minimum of 10 per cent of recycled C&D waste in construction. It’s about time to craft national guidelines on C&D waste.

While the transition from river–sand to manufactured– sand and recycled–sand is a good augury, there are environmental issues that remain to be addressed. “It is essential to ensure that these new genre plants adhere to strict pollution norms. Communities living near or around these plants are already restive,” says Sumaira Abdulali of the Mumbai-based Awaaz Foundation that has been campaigning against illegal sand mining for years.

A few plants on the outskirts of Pune have already been forced to shut down by agitating farmers.

So, Start using M Sand for Constructions Which has more advantage than River Sand

How to Make Best Concrete Mixture

Well, Everyone knows how the concrete is made. It is done by mixing Cement, Water, Fine Aggregates (Sand), and Coarse Aggregates (Jelly). But we all must know what is the best mixing ratio to get the best quality concrete.

What is Ratio of mixing M Sand for Concrete? There is no difference of mixing M Sand and River Sand (RV). The ratio is same for M Sand as you mixing river sand but thing is you should use a Good M Sand.

But best Mixture ratio depends on conditions and situation where you are using the concrete mixture. If you are using mixture in a water flow area than your mixture should with stand more corrosion.

concrete mixture ratio

The Best Mixture for M30 is C: W: FA: CA = 1:05:1.89:3.04. C = Cement, W = Water, FA = Fine Aggregate, CA = Coarse Aggregate.

This is only a standard Mixture you should mix the concrete depending up on your situation and condition for the best result.

You can check the standard mixture result below link

M Sand Vs CRF (crushed rock fines)

Everyone knows that River sand (RS) and crushed rock fines (CRF) have been used as an aggregate for concrete for centuries. Now the River sand (RS) has been banned in many places due to its adverse effect on the river and environment.

The Crushed rock fines (CRF) has a major problem in its angular shape and containing excessive fines. So, this was not good for constructions as it weekends the structure of the building and develops more cracks on the concrete wall in a short period of time. So, people hated using it for their buildings after that Crushed rock fines (CRF) have been modified to resolve this problem, and the technology of processing the Crushed rock fines (CRF) to reduce the fines and improve the particle shape has been developed the modified or processed crushed rock fines (CRF) are known as M Sand.                         

Now many constructors started using the M Sand which stronger than River Sand (RS). But as Crushed rock fines (CRF) and M Sand look like same in colour some people sell the Crushed rock fines (CRF) as M Sand in market so be aware while purchasing the M Sand.

How to identify the difference between M Sand and crushed rock fines (CRF)

If you find your M Sand contain lot of Dust particles than you should check the lab report of that particular M Sand because lot of Dust particles are found in Crushed rock fines (CRF).

Crushed rock fines (CRF) look like Talcum powder which is very nice and soft.

There are certain standards for preparing M Sand. M Sand are manufactured in Three different forms.

  1. M Sand for Concrete – Grading zone – II and IS 383
  2. M Sand for Block work – IS 2116
  3. M Sand for Plastering (P Sand) – IS 1542    

There few simple steps to identify the Quality of M Sand with the best quality M sand you always get the best results.

Tavara Sands are M Sand Manufacturers and Suppliers in Bangalore for more than 12 years in this field you can get the best quality M Sand with IS standards. Now Tavara have their branch in Mysore too.

River Sand (RS) Vs M Sand

How River Sand are Formed

Over Many Centuries mankind used river sand for constructions. Rivers are Naturally origin in Mountains and Ends in Ocean or Sea. When the water runs down from the mountain it just grains the Mountain and takes some stones with it and as the days runs these stones are rolled in the flow of water and converted into sands. This sand is deposited in the Through the river. In some Depth areas of River, this sand is found more. But it takes Many years for Nature to make the sand.

We have used it for constructions over many years as the civilization of mankind grow many constructions have been started and more amount of the sand is taken from the river. This activity makes the river go deeper in some area where more amount of sands is taken it also causes an imbalance in the River.

So, in order to save this Many Government prohibited to take sands from the river. So many Construction companies now started using the M Sand.

How M Sand are Manufactured

The full form of M Sand is Manufactured Sand. M Sand is made by crushing the stones and making it for Construction. There are a lot of processes takes place in the Manufacture of M Sand.

But buying a Best quality M Sand is very important and you can check the quality of M Sand by simple test.

Please Avoid using Crushed rock fines (CRF) as it is not good for Construction. More over Crushed rock fines and M Sand look similar in colour but M Sand is Modified or Processed stage of Crushed rock fines (CRF). 

Tavara Sand is M Sand Manufacturers in Bangalore who provides good and pure M Sand in Bangalore and Mysore. M Sand are stronger than River Sands.

Can M Sand Used for Plastering a Wall?

Many of our Constructions have this doubt whether M Sand can be used for Plastering a Wall.

I would like to start with a real time example which happened back in 2013. It was a terrible time where sands where not available and I was in a tender which I have to finish in a week. We used m sand for construction and it was totally good. With no choice left i used M Sand for Plastering and it was terrible the finish looked like texture finish. We tried in different combination by adding less water etc but the result was the same.

After that in 2015 I found a Real estate constructor using the M Sand for the wall plastering I said it will not work as it was a house to my surprise the sand was so soft and it gave an excellent finish now, I asked how. He said it’s a P Sand.

Now the Thing you should know is there are Three Variant available in M Sand.

  1. M Sand for Concrete
  2. P Sand
  3. M Sand for RCC & Brick and Block

Now as the Name Suggest P Sand (Plastering M Sand) can be used for Plastering and you get Good Result in cost wise P Sand is Little bit higher than M Sand for Concrete. But Don’t use Concrete M Sand for Plastering. While you buy a M Sand please Check it quality. If you want to know how to Check M Sand quality check our previous blog. Tavara Sands is one of the Best M Sand Manufacturers in Bangalore.  

How to Check the M Sand Quality

  • Take a Glass of Water and put the M Sand in it and Shake it nicely and allow the water and sand to settle down. If you find the clay content in M Sand than its a poor-quality M Sand.
  • Take some sand and Taste it if you find the salty taste in the sand than it indicates the presence of salt in the content never use that sand as the salt weekend the structure.
  • Take a Sand and Just rub it in your hand if your hand stained it indicates the earth materials which is not good for a mixture.
  • The Colour of the sand may indicate the purity of the sand if you find any shining substance in the sand than that indicates the impurity in the sand.
