Use of Fly ash while in Construction

Dear Naresh

Use of Fly Ash in the concrete:-

                          Fly ash with ordinary Portland cement (OPC) when used in concrete mix can save the quantity of cement.  Fly ash can be used in concrete in two ways, one is direct use and other is in the factory.  In the direct use the fly ash is used as a separate ingredient at the concrete batch plant or, can be blended with the OPC to produce blended cement which is called Portland-Pozzolana cement (PPC) in India. Fly ash blended cements are produced by several cement companies in India. In general, the use of fly ash in the concrete industry with OPC cement is normally ranges from 15 to 25%. If concrete is properly designed, the use of fly ash in concrete will improve some aspects of the performance of the concrete. The use of fly ash can increase long-term strength of the concrete and enhance the durability. The use of fly ash also helps to creates significant benefits to the environment. The use of fly ash in concrete reduces green house gas emission without negative impacts on the economy.
