COMPRESSIVE STRENGTH OF LIME STONE AGGREGATE CONCRETE WITH CRIMPLED STEEL FIBER-II

Cementations materials have been used by mankind for construction from time immemorial. The every rising functional requirement of the structures and the capacity to resist aggressive elements has necessitated developing new cementations materials and concrete composites to meet the higher performance and durability criteria. The environmental factors and pressure of utilizing waste materials from industry have also been the major contributory factors in new developments in the field of concrete technology. Concrete is an artificial material in which the aggregates both fine and coarse are bonded together by the cement when mixed with water. The concrete has become so popular and indispensable because of its inherent in concrete brought a revolution in applications of concrete. Concrete has unlimited opportunities for innovative applications, design and construction techniques. Its great versatility and relative economy in filling wide range of needs has made it very competitive building material. At present there is depletion for both fine and coarse aggregates. Too much usage of good qualities of materials for concrete works is scares for future generation. Hence there is a search for other second grade and novel material to produce desired strength concrete. In this connection an attempt has been made, the use of lime stone aggregate (replacing of granite aggregate by lime stone aggregate in proportion of 25, 50, 75 and 100%) with incorporation of 2% crimpled steel fiber for concrete works. Here an attempt made to use of lime stone aggregate in concrete to evaluate the workability and compressive strength.
