AN EXPERIMENTAL INVESTIGATION ON PARTIAL REPLACEMENT OF CEMENT BY ALCOFINE, MICROSILICA AND FLY ASH IN M25 GRADE CONCRETE

摘要

The main objective of this research is to find that if there is any change in the strength of concrete even after the cement is partially replaced by Alcofine and Microsilica and Fly ash by various portions (5%, 10%, 15% and 20%) respectively. The cost of material plays a vital role in construction industry in the present day scenario so we need to find out materials which are economical as well as sustainable. The main aim of this research is to find out the difference in strength in concrete when the cement is replaced by Alcofine, Micro silica and Fly ash in the proportion of various %. In this study we have found out the compressive strength of cube, split tensile strength of cylinder and flexural rigidity at the end of 3 days, 7 days and 28 days. The test result are noted and tabulated and graphs are made according to the values.
