Abstract

This paper presents the experimental investigation carried out to determine the mechanical properties of coir fibre reinforced high strength concrete of grade M50 incorporating fly ash (FA) and densified silica fume (DSF). Three different compositions of coir fiber reinforced concrete (CFRC) were made. First CFRC without additives, second CFRC made by 10% replacement of cement mass with FA, in the third composition 10% of cement mass was replaced with DSF. In each mentioned admixture, coir was added in its natural length by 0.4% of the binder volume. The mechanical properties viz., compressive strength, flexural tensile strength, density and elasticity modulus of all mixes has been determined. The investigations revealed that adding coir fibres to high strength concrete caused a slight reduction in density and compressive strength of concrete by about 1.5 and 1.2% respectively. However, it improved the flexural tensile strength and dynamic elasticity modulus by 4 and 9%. Improvement of ductility in presence of coir has been proven through direct observation and experiment. Coir fiber reinforced concrete contains FA presented the highest strength compared to other mixes with about 8% higher strength compared to control concrete. It also presented the highest quality through sonic investigation followed by CFRC without additive and CFRC incorporating 10% DSF.
