An Experimental Study on Properties of Concrete using RHA and RFA as a Partial Replacement of Fine Aggregate and Fly Ash as a Cement

Concrete is the most widely used construction material in the world it is a mixture of cement, sand, coarse aggregate and water. Storage and safe disposal of industrial byproduct such as fly ash and RHA and RFA is a huge problem everywhere, reuse of these waste eliminates reduce the problem. In this experiment fine aggregate is replaced 0 , 6 6 and 12 12 , of its weight by RFA RHA and cement is replaced 0 , 10 , 15 and 20 of its weight by fly ash in all concrete mix and there effects are studied. In this experiment the compressive strength of the concrete is increased , It is found that the maximum strength increases with the replacement of cement and fine aggregate by fly ash at about 10 and 6 RHA and 6 RFA, after that compressive strength is decreases.
