3. Results and Discussions 3.1. Crushed Aggregate’s Effects on Slumps of Concrete. The Figure 1 depicts slum value of A-1 coarse aggregates for all five groups. For Impact Crushed (A-1) coarse aggregates slump values were evaluated for all five groups and it was evident from experiment that, there was a steady decrease in slump value with the decrease of w/c ratio.
• Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions. • Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements. 51.

~Indian Roads Congress and IS) have specified that the aggregate crushing value of the coarse aggregates used for cement concrete pavement at surface should not exceed 30 percent. For aggregates used for concreteothet than for wearing surfaces, the aggregate crushing value shall not exceed 45 percent, according to the ISS.

Aggregates used in the construction, should be strong enough to resist crushing. If the aggregates are weak, the stability of the structure is likely to be adversely affected. The strength of coarse aggregates is assessed by aggregate crushing test. The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied compressive…
The average crushing value in the different tests is the actual crushing value of aggregate. Important points to remember. It is recommended that the crushing value of aggregate should be less than 30%. If it is more than 30 % then 10% finer aggregate is suggested to use. The aggregate whose crushing value is less than 30% can be used for
