limiting value of crushing strength of coarse aggregate

“Effect of Specific Gravity on Aggregate Varies the Weight ...

increases volume of coarse aggregate and increases in weight of concrete cube. If the fineness Modulus is constant, the volume of coarse aggregate increase with size of the aggregate, or with the decrease in surface area of the coarse aggregate The main cause in variation in weight of cube found to be specific gravity of Coarse Aggregate.
