SKGC Manufactured Sand

As a responsible enterprise to produce Eco sustainable products we would emphasize here On the advantage of Manufactured Sand over River Sand. Manufactured Sand is the perfect substitute for River Sand. It is not only technically better but also necessary to opt for environmental reasons.

Now-a-days, Vastu Shastra is more popular, consults Vastu by many people while constructing a house. As per Vastu Shastra, the building material must be free from traces of human or animal body. The river sand contains bone of human beings and animals. The shells are also a kind of bone. It is not easy to take out all such things present in the river sand. Hence, the best solution for this is to use manufactured sand of goods quality for human well-being.

• Improves compressive strength by reducing voids.
• Highly consistent resulting in optimum mix designs.
• Absence of organic impurities. Reduces alkali aggregates re activity, reducing cracks in concrete.
• Single source material consistent uniform quality.
• Can be scientifically graded to comply BIS specification.

Usage of River Sand has the following ill-effects on the environment.

1. Due to digging of the sand from river bed reduces the water head, so less percolation of rain water in ground, which result in lower ground water level.
2. Destroy Flora & Faunae in surrounding areas
3. Erosion of nearby land due to excessive sand lifting.
4. Using Manufactured Sand help minimizing solid waste contributing greatly to environment requirement.
5. Diminishing of Natural Rivers or river beds, not available for future generations.

Many State governments like Kerala, Karnataka, Maharashtra fi lade it criminal offence to use natural sand due to environmental concerns. Metro Projects in all these States are wing only Manufactured Sand.

The excessive mining of river bed to meet the increasing demand for sand in construction industry has led to the ecological imbalance in the state. Now the sand available in the riverbed is very coarse and contains very high percentage of silt and clay. The silt and the clay presence in the sand reduce the strength of the concrete and hold dampness. The natural river sand is the product of sedimentation, mica, coal fossils and other organic impurities are present in the river sand above certain percentage which make the sand useless for concrete work.

Acute shortage and high price for river sand has led to the adulteration of sand with salty sea sand/fine sand has raised serious concern among builders.
