Durability Study on Coir Fibre Reinforced Concrete

Abstract

The use of fibres in concrete has demonstrated excellent structural performance, there still exists the need for understanding the durability of fibre reinforced concrete in the environment to which concrete structures are generally exposed. The aim of this study is to evaluate the durability properties of coir fibres in the structural concrete. Experimental investigation explores durability properties such as water absorption, acid resistance and sulphate resistance. The fibre volume fraction ranges from 0 to 3% for a length of 1.5 and 3cm. From the experimental investigation, it was found that there is improvement in durability properties for coir fibre reinforced concrete when compared to plain cement concrete. Also coir reinforced concrete improves the cracking resistance compared to plain cement concrete.
