STRENGTHAND DURABILITY OF CONCRETE BY USING SILICAFUMEAND GGBS


Abstract

This thesis presents a study conducted on mechanical and durability properties of concrete. The investigation covered concrete mixes at water cementitious material with ratio of 0.4. Ordinary Portland cement of 53-grade was used in this study. The percentage of cement that partially replaced by weight were Silica Flume is 10% and varying the GGBS replacement from 0% to 50%. Concrete cubes and cylinders were casted and tested in laboratories. The optimum proportion of replacement was found by conducting tests on mechanical properties like Compressive strength test and Split tensile strength test.
The results show that the optimum replacement of cement with silica flume 10% and 40% GGBS, it is possible to gain the same strength as conventional concrete. The durability of concrete was done by curing with 5% Hydrochloric acid (HCL) and 5% Sulphuric acid (H2SO4). The effect of acids on compressive strength, Split tensile strength and durability characteristic property was determined for 7, 28, 60, 90 and 180Days.
