K, Simon Jayasingh Assistant Professor, School of Civil and Chemical Engineering, Vellore Institute of Technology, Vellore, Tamil Nadu ABSTRACT The paper deals with the experimental investigation on the determination of axial stress-strain relation, the concrete thoroughly made with the lightweight aggregate of coconut shell. Four different grades of coconut shell concrete were used in the experiment. The coefficient of secant modulus and modulus of elasticity and chord modulus variations were observed. The experiment is entirely done with extensometer, stress-strain relations were observed. The empirical equations were finally proposed to describe the stress-strain relation of coconut shell concrete. Key words: Coconut Shell Concrete, Axial Stress-Stress Relation, Strain Gauges.

INTRODUCTION 1.1. General Coconut shell concrete (CSC) is one of the unique concrete under lightweight concrete which is recently developed in the concrete world. The mechanical properties and bond properties of CSC [1] and durable properties of CSC [2] and torsional behavior of CSC [3] and excellent flexural and ductility behavior [4] are in acceptable range and similar to the lightweight concrete. Compressive strength, porosity in the concrete, water-to-cement ratio and curing temperature affect the development of stress-strain relation of concrete [5] and also an internal matrix of aggregate hugely impact on the stress-strain behavior and Poisson's ratio. In the experimental program, we made an attempt that we have developed four mix proportions of
