Benefits of Fly Ash Usage
Fly ash is a bi-product of coal based thermal power stations generated by the combustion of pulverized coal. It is a pozzolanic material rich in silica & alumina and spherical in shape. The commonly known benefits of using fly ash in concrete are:

     Workability


    Reduced permeability

    

    Reduced heat of hydration

    

    Improved pump-ability

    

    Improved sulphate and chloride resistance

    

    Reduced risk of alkali aggregate reaction

    

    Increases long term strength

    

    Better concrete finish

    

    Reduced bleeding and segregation
 

    Reduced shrinkage and many more

Green Benefits
Today, fly ash is one of the greatest energy saving resource and as a recycled material, it creates significant benefits for the environment. Harmful CO2 emissions or greenhouse gases are reduced when fly ash is blended with cement or used as a cement extender in concrete applications. For every ton of cement replaced by fly ash, it enables less energy to be consumed and there is a marked improvement in the environmental footprint of the concrete.
