LOW-CALCIUM FLY ASH-BASED GEOPOLYMER CONCRETE

the fly ash is not effectively used, and a large part of it is disposed in landfills. As the need for power increases, the volume of fly ash would increase. Both the above issues are addressed in our work. We have covered significant area in our work, and developed the know-how to manufacture low-calcium fly ash-based geopolymer concrete.

Using Fly Ash in Concrete

Fly ash also benefits precast concrete by reducing permeability, which is the leading cause of premature failure. The use of fly ash can result in better Properly proportioned concrete containing fly ash should create a lower cost. Because of the reduced permeability and reduced calcium oxide in

Effect of parameters on the compressive strength of fly

The replacement of cement by fly ash in geopolymer concrete reduces the huge energy consumption and restricts carbon dioxide emission to the atmosphere during its production.
