compressive strength analysis of concrete with various aggregate In very high-strength concrete mixtures (greater than 70 MPa) the crushing strength of the aggregate can be a limiting factor to the ultimate compressive strength. In lean concretes (with a high water-cement ratio) the crushing strength of the aggregates is not so significant.

The ultimate strength of concrete is related to water/cement ratio and the size, shape, and strength of the aggregate used. Concrete with lower water/cement ratio (down to 0.35) makes a stronger concrete than a higher ratio. has high compressive strength, low tensile strength Brittle Withstands high temperatures Behaves as a ceramic

Thus, to take into account all the effects of MSA on compressive strength of concrete, the IS Codes limit the maximum size of aggregate to be used in construction to 20 mm.

Predicting Compressive Strength of Concrete

Abstract: This paper deals with development of regression models for prediction of compressive strength of concrete. The compressive strength of concrete is predicted using four variables, namely, water-binder ratio, fine aggregate-binder ratio, coarse aggregate-binder ratio and binder content.

COMPARATIVE ANALYSIS OF THE COMPRESSIVE STRENGTH

compressive strength analysis of concrete with various aggregate concrete resists the compressive stresses to which it is subjected depends largely on the compressive strength of the concrete which in turn depends on the quality of the concrete. Since seventy ve per cent of concrete is made up of aggregates, its types, quality and general properties determine the quality of
