The modulus of elasticity of concrete is a very important parameter reflecting the ability of concrete to deform elastically. In order to utilize the full compressive strength, the structures using high strength concrete tend to be slimmer and require a higher elastic modulus to maintain its stiffness. The mechanical properties of HSC are mostly dependent on the properties and proportions of binders and aggregates. Therefore, knowledge of the modulus of elasticity of high strength concrete is very important in avoiding excessive deformation providing satisfactory serviceability and avoiding the most cost-effective designs. This paper presents the results of experimental study of modulus of elasticity of M60 grade concrete using standard cylinder specimens tested with compressometer under axial compression. Based on the test results, it is observed that the stress-strain behaviour exhibits non-linear variation from which the initial tangent modulus is plotted to arrive at modulus of elasticity values.
