Abstract |
Due to rapid growth in automobile industry, use of tyre increases day by day and there is no reuse of the same to decrease the environmental pollution. The decomposition and disposing of waste tyre rubber is harmful to environment. This research reflects the reuse of waste tyre rubber into concrete after observing their properties. In that experimental work rubber aggregates replaced to the natural coarse aggregates by varying percentage of 1,3and 5 with comparison of 0% replacement. Silica fume is replaced in 5% with cement for improving the bond properties between cement paste and rubber. In evaluation, test has been carried out to determine the properties of concrete such as workability, compressive strength, flexural strength and split tensile strength. The workability of fresh concrete is observed with the help of compaction factor test vee bee test, slump cone test, flow table test. From the test of compaction factor, workability is decrease with increasing percentage of rubber. The specific gravity of rubber aggregates is 1.25. It is lower as compared to natural aggregates therefore decrease the unit weight of rubber mix concrete. Increasing rubber aggregates as partial replacement into concrete reduces compressive strength. So these can use in non-primary structural applications of medium to low strength requirements. The overall results of study shows that it is possible to use recycled rubber tyre aggregates in concrete construction as partial replacement to natural coarse aggregates. |
