USE OF DIFFERENT MATERIALS FOR PARTIAL SUBSTITUTION OF FINE AGGREGATES WITH MIX PROPORTION M35

This paper under seeks the effect on the compressive strength and split tensile strength of concrete by partial replacement of fine aggregates by mixture of ceramic tile powder and brick powder in equal proportions the reason for using ceramic as fine aggregates is that it is a waste material usually found in the form of damaged roof tiles. Brick makes cement mortar and concrete more water proof and also more resistant to alkali and salt action as compared to those in which no brick powder is present. Thus, this combination of ceramic and brick powder as replacement of fine aggregates not only makes the concrete mix economical but also makes it more resistant to various attacks, that to without decreasing its strength. For conducting the tests, initially a portion of conventional fine aggregate (i.e. sand) was replaced by equal proportions of ceramic and brick powder till all of fine aggregate got replaced. The results obtained from various tests conducted on concrete of grade M35 analyzed and ultimately compared to that of the standard M35 grade. It was observed that with increase in the percentage of ceramic and brick powder the compressive and split tensile strength of the concrete mix increased, with its maximum value for the specimen in which 80% of the fine aggregates got replaced by mixture of ceramic and brick powder. For the specimen in which all of conventional fine aggregate was replaced by mixture of ceramic and brick powder, there was a slight decrease in values of compressive and split tensile strength.
