Abstract
As construction activity is increased in recent days, requirement of construction materials such as cement, sand, aggregates etc. has also increased by leaps and bounds. But the builders are facing lot of problems in regard to unavailability of natural sand or unaffordable M-sand. So there is a need to find an alternative material at lower cost which can perform same as natural sand. Now a days there have been lot of efforts on various alternative materials such as quarry dust, saw dust, copper slag, crushed recycled aggregates, bagasse ash etc. to use as fine aggregates with satisfactory strength and durability properties of concrete. Also as plain concrete is weak in resisting tensile stress and flexural load with the development of cracks, use of various fibers such as steel fibers, carbon fibers, glass fibers, plastic fibers, coir fibers etc. can increase the load carrying capacity of concrete in tension and flexure. The present study involves use of polyester fiber for 0%, 1%, 1.25% and 1.5% of cement content and slag sand at 0%, 10%, 15% and 20 % as replacement of fine aggregates respectively. The test results revealed that there is an increase in the strength properties of the concrete containing fiber content of 1.25% and 15% slag sand as partial replacement of fine aggregates.
