Acute shortage and high price for river sand has lead to the adulteration of sand with salty sea sand which has raised serious concern among builders. The natural river sand was the cheapest resources of sand. However the excessive mining of rive bed to meet the increasing demand for sand in construction industry has lead to the ecological imbalance.
High Strength
The superior shape, proper gradation of fines, smooth surface texture and consistency in production parameter of chemically stable sands provide greater durability and higher stren ....etc

Geopolymer cement is often mixed up with alkali-activated slag developed since 1956 in Eastern Europe by G.V. Glukhovsky. Alkali-activation, which is generally performed with corrosive chemicals (see below User-friendly), is used for the making of concretes exclusively. The alkali-activated materials are not manufactured separately and not sold to third parties as commercial cements. On the opposite, geopolymer technology was from the start aimed at manufacturing binders and cements for various types of applications.
In this section we are dev ....etc

The cement industry is the India s second highest payer of Central Excise and Major contributor to GDP. With infrastructure development growing and the housing sector booming, the demand for cement is also bound to increase. However, the cement industry is extremely energy intensive. After aluminium and steel, the manufacturing of Portland cement is the most energy intensive process as it consumes 4GJ per tonne of energy. After thermal power plants and the iron and steel sector, the Indian cement industry is the third largest user of coal in t ....etc

Geopolymer Concrete:

Geopolymer was the name given by Daidovits in 1978 to materials which are characterized by chains or networks or inorganic molecules. Geopolymer cement concrete is made from utilization of waste materials such as fly ash and ground granulated blast furnace slag(GGBS). Fly ash is the waste product generated from thermal power plant and ground granulate blast furnace slag is generated as waste material in steel plant.

Both fly ash and GGBS are processed by appropriate technology and used for concrete works in the form o ....etc

Geopolymers are inorganic, typically ceramic, materials that form long-range, covalently bonded, non-crystalline (amorphous) networks . Obsidian is an example of naturally-occurring geopolymer. Commercially produced geopolymers may be used for fire- and heat-resistant coatings and adhesives, medicinal applications, high-temperature ceramics, new binders for fire-resistant fiber composites, toxic and radioactive waste encapsulation and as cementing components to make concrete. The properties and uses of geopolymers are being exp ....etc
