Bonding characteristics of water hyacinth ash on concrete by replacing cement

Abstract

The study explicates the experimental investigation of bonding properties of M30 grade concrete with and without replacement of cement by water hyacinth ash. The main parameters in this study are a grade of concrete, the diameter of the bar, embedded length and cause of water hyacinth ash. The study of the bonding strength of concrete is investigated by two stages. First stage concrete is cast and tested without any replacement. The Second stage, concrete is cast and tested with 10% replacement of cement by water hyacinth ash. The bars (10mm diameter and length 200 mm) are cast with concrete in the cylinder and cured for 28 days. Pull test out the experiment is carried by a universal testing machine. The results show water hyacinth ash enhances the bonding strength of concrete when compared to the normal concrete after 28 days.
