Thus modulus of elasticity does not follow the compressive strength. It should be noted that the indicated strength of concrete increases as the size of specimen decreases, whereas modulus of elasticity decreases. These relations give only approximate value of these properties. However some statistical or empirical relations have been established between them to be used in the field work. No exact qualitative relationship between the compressive strength and other properties like tensile strength, flexural strength, modulus of elasticity, wear resistance, permeability and fire resistance exists. It is also used as a qualitative measure of other properties of hardened concrete. Thus the concrete making properties of ingredients of the mix are usually measured in terms of the compressive strength. In situations where the shear or tension strength is of importance, the compressive strength is usually used as a measure of these properties. In most of the structural uses, the concrete is used mainly to resist the compressive stresses. The compressive strength of hardened concrete is one of the most important and useful properties of concrete.
