Abstract
Nowadays the abnormal use of sand quarrying resulted in scarcity and significant increase in its cost. In order to fulfill the requirement of fine aggregate, some alternative material must be found. The cheapest and the easiest way of getting substitute for natural sand is obtained from limestone quarries. Research shows use of lime in concrete improved its strength and durability properties Research shows use of lime in concrete improved the strength properties. This paper summarize and discuss the effect of the limestone Filler (Fine Aggregate) CaMg(Co3)2 as a compensating material with different ratio of sand include 0%, 10%, 20%, 30% , 40% and 50% Steel Fibers are generally used as resistance of cracking and strength of concrete. The steel fibers were employed at constant volume fraction of 0.5% throughout in all mixes. Compressive and Split tensile strength were investigated and optimum percentage limestone Filler (Fine Aggregate) is found out and flexural strength for the optimum percentage limestone Filler (Fine Aggregate) concrete is found out.
