A STUDY ON MECHANICAL PROPERTY OF CEMENT WITH PARTIAL REPLACING SECONDARY CEMENTITIOUS MATERIALS

Abstract

In recent years, a lot of interest has been developed among the civil engineering community regarding Secondary Cementitious Materials (SCM) in concrete. The ingredients that have to Moreover since ground granulated blast furnace slag (GGBS), Fly ash and Silica fume (Bhanja, et al., 2005) industrial by products and the quality of the end products may depend heavily on the quality of these byproducts. By considering the above threat a study was carried out in M40 grade of concrete with the fractional substitute of cement by GGBS, fly ash and silica fume with different percentages. our work presents a detailed study on its strength parameters like Compressive strength, split tensile strength and flexural strength for period of 7 days, 14 days and 28 days respectively. From this process, it reveals that the increase in fractional substitute of cement by SCMs increased the compressive, split tensile strength and flexural strength with the Partial replacement of OPC by GGBS 20 % + SF 10% gives the better result than the normal type of concrete.
