Prediction Of Compressive Strength Of Concrete From Early

CONCRETE AND COMPRESSIVE STRENGTH Concrete is inert mass which grows from a cementing medium. Concrete is a product of two major components, one is the cement paste and another is the inert mass. In order to form the cementing medium, cement would mix with water. Coarse aggregates and fine aggregates are the part of inert mass.

The compressive strengths were taken as the average values of three cylinders tested.

Relation Between Compressive And Tensile Strength

Compressive Strength The main measure of the structural quality of concrete is its compressive strength. This property of concrete is commonly considered in structural design. Depending on the mix especially the water-cement ratio and time and quality of the curing, compressive strength of concrete can be obtained up to 14,000 psi or more. Commercial production of concrete with ordinary .
