### Compressive and Tensile Strength of Concrete: …

On the basis of test data of the study, CRRI has suggested the following relation between flexural strength and compressive strength of concrete: y = 11 x – 3.4 . where y is the compressive strength of concrete in MPa and x its flexural strength. This relation depends on the size of coarse aggregate. The strength is found to vary with the nature and size of aggregate.

### Effect of Rate of Loading on Compressive Strength of Concrete

In this project the effect of high rate of loading on compressive strength of concrete has been studied. As it has been observed that strength increases at higher rate of loading, it gives false strength which may prove hazardous. To avoid this, a suitable correction factor has been formulated which will enable us to obtain the true strength of ...
