Improvement of Strength of Concrete with Partial Replacement Of Course Aggregate With Coconut Shell and Coir Fibres

Abstract

Coconut shell and coir fibres are the natural materials which is abundantly available in tropical regions. Wastes generated by industrial and agricultural processes have created disposal and management problems which pose serious challenges to efforts towards environmental conservation. A considerable amount of coconut shells and fibres remain in the environment as waste, so utilization of these materials for construction will be an important step to improve sustainability and eco-friendly construction. In addition to that it will help to produce light weight and economically profitable materials in construction field. The current study examined the suitability of partial replacing of coarse aggregate with coconut shell and coir fibres. To compare the above, test for compressive strength, splitting tensile strength, temperature resistance, water absorption, electrical resistance, chemical resistance, pH test of sample were performed. The specific gravity, bulk density and water absorption of coconut shell and fibres were analyzed. A study on the economic aspects was also carried out.
