The manufacture of Portland cement is environmentally unfriendly because for each ton of cement produced, approximately the same amount of CO2, in addition to this, CH4 and NO, which are major green house gases, are released into the atmosphere are also released into the atmosphere. Investigations have revealed that, replacing part of Portland cement by industrial by-products such as blast furnace slag and fly ash in concrete can contribute significantly to the reduce the emission of these green house gases and also save energy. The main objective of the investigation is an attempt to compare the properties of fresh concrete, strength of hardened concrete produced from four different types of cement namely, blended cement (Portland Pozzolana and Portland Slag Cements i.e. PPC & PSC), and 43 & 53 Grade OPC. Investigations are carried out on M30 grade of concrete with a water-cement ratio of 0.45. The results of the present investigation clearly indicate that the performance of blended cement concrete is better than that observed for 43 and 53 grade OPC concretes.
