Effects of Supplementary Cementing Materials on the Mechanical Properties of Concrete

In today's competitive environment it is becoming important to reduce the construction cost in one or other way. Now a day's OPC is widely used and it is the costly ingredients in the production of concrete. However many countries have severe shortage of cement although there requirements are vast. The manufacture of OPC is expensive and skill intensive process, besides polluting the environment heavily production is associated with the emission of carbon dioxide which is a significant source of global warming. Pozzolanic materials are widely used in concrete and mortars for various reasons particularly for reducing the amount of cement required for making concrete and mortar which lead to a reduction in construction cost. This paper presents the results of study under taken to investigate the feasibility of using Supplementary Cementing Materials (SCMs) as partial replacements of cement. The effects of replacing cement by these SCMs on compressive strength, split tensile strength are evaluated in this work. Both compressive and spilt tensile strength is evaluated at 7days, 28 days, 90 days and 180 days.
