AN EXPERIMENTAL INVESTIGATION AND DURABILITY PROPERTY ON RECYCLED CONCRETE WITH PARTIAL REPLACEMENT TO FINE AGGREGATE IN COCONUT SHELL CONCRETE

摘要

Concrete is a matrix mixture in the 18th century this mix has become a revolutionary material and used in the site for construction, the latest replacement to fine aggregate has invented and is name as recycled aggregate. The crushed building material is used as a sand replacement in concrete. The compressive strength and impact strength will be compared to normal concrete. Coconut shell aggregate concrete has been established using other conventional concrete constituents expect coarse aggregate. Nowadays, the resources of river sand are exploited and facing many problems by the society because of nonavailability of river sand. Hence recycled aggregate is used for the production of concrete at presents. Here coconut shell is taken as a coarse aggregate and recycled aggregate as fine aggregate in the production of concrete. This study is aimed to investigate the durability performance of coconut shell aggregate concrete with demolished aggregate.
