Study On Utilisation Of Building Materials From Demolished Structures

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 of M30. 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 are to be carried out with the use of GGBFS as mineral admixture. 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.
