Enhancing The Strength Properties Of Recycled Aggregate Concrete Through The Use Of Supplementary Cementing Materials

Abstract

Recycling of concrete waste aggregate is a hot topic. Numerous papers, reports and articles have been prepared illustrating how we could and should make greater use of recycled aggregate in the construction industry. The present project makes an effort to asses a safe and economic use of such concrete as a structural grade concrete M15 and M20. Extensive tests for structural properties such as workability, compressive strength, split tensile strength and flexural strength tests on concrete specimens made up of recycled and natural aggregate were carried out. The experimental results showed that recycled aggregate has a significant effect on the overall property of the concrete. The recycled aggregate concrete can be used as a substitute for the natural aggregate and it is necessary from viewpoint of environmental preservation and effective utilization of resources. Further the replacement of crushed concrete waste will lead to saving in the cost of the aggregate.
