3. Results and Discussions Crushed Aggregate's Effects on Slumps of Concrete. The Figure 1 depicts slum value of A1 coarse aggregates for all five groups. For Impact Crushed (A1) 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.

This may be assessed by tests of aggregate impact value (AIV) and aggregate crushing value (ACV). The common rock types range in AIV from good (basic volcanic, dolerite, quartzite. quartz gravels), through fair (granite, gravels composed of igneous or metamorphic fragments) to poor (weathered igneous rocks, clayrich gravels).

This part of ISO 20290 gives the determination of aggregate crushing value (ACV) of aggregates. This gives a relative measure of the resistance of the aggregate crushing under the gradually applied compressive load. The method is applicable to aggregates passing a 14,0 mm test sieve and retained on a 10,0 mm test sieve.

Ten percent fines value is a measure of the resistance of aggregate crushing subjected to loading and it is applicable to both weak and strong aggregate. Fine aggregates are defined as those passing sieve. The test aims at looking for the forces required to produce 10% of fine values ( weight of fines aggregates/weight [.]
