STUDY ON DETERMINATION OF COEFFICIENT OF MODULUS OF ELASTICITY FOR COCONUT SHELL CONCRETE

In developing countries, the wide spread use of concrete increased its cost leading to a price hike in construction. This, combined with the disastrous effect of concrete production on the environment compelled studies on different alternatives that provide use as replacement for coarse aggregate. So study on substitute concrete materials produced using crushed, granular coarse aggregate for complete replacement of coconut shell is essential. Determining modulus of elasticity for coconut shell concrete is the main aim of the study. For structural analysis, the modulus of elasticity is one of the premium parameters. This is necessary for evaluating strain behavior and displacements, particularly when design depends on elasticity considerations. One of the important reasons has been proved that mechanical properties of concrete depend on the aggregate proportions and properties to the significant extent. M25 grade of Coconut shell concrete was attained by using 510 kg/m3 of cement. Cylinder specimens were cast to determine the stress-strain characteristics. From the stress-strain characteristics and regression analysis of the experimental data, empirical equations have been formulated to predict coefficient of modulus of elasticity
