摘要：Concrete is a very common construction material and based on guidelines of IS 456 : 2000 and IS10262 : 2009 or IRC 44 : 2008 concrete mix is designed. For ordinary Portland cement, maximum cement content(OPC) is limited to 450 kg/m3 of concrete. In design mix M30 grade concrete, chemical admixtures and fly ash wereused for reduction in cement content. In M30 grade design mix concrete, cement content was 400.826 kg/m3 andcement content was replaced by fly ash in varying proportion. For 25% cement replacement by fly ash, compressivestrength was found satisfactory and reduced cement content was 330.71kg/m3 of concrete. Design mix M30 gradeconcrete mix samples with 0.5%, 1.0%, 1.5%, 2.0% and 2.5% super plasticiser were tested. Compressive strength for1.5% use of super plasticiser was found optimal with reduced cement content 328.71 kg/m3 of concrete.
