The strength and the stiffness of coarse aggregate directly influence the behavior of hardened concrete Although in normal concrete, strength is controlled by the paste or by the transition zone between paste and aggregate, the strength of highperformance concrete depends not only on the strength but on the mineralogy of coarse aggregate as wellCrushed stone is produced by crushing quarry rock, boulders, cobbles, or largesize gravel Crushed aircooled blastfurnace slag is also used as fine or coarse aggregate Strength to exceed 95% of strength aggregate failing other tests ASTM C 78 (AASHTO T 97) strength achieved with purified sandAggregates for ConcreteAug 07, 2010 An analysis of the abrasive wear of concrete floors has revealed that highintensity crushing is the chief mechanism of deterioration, and hence the concrete crushing strength is the relevant parameter determining wear resistance 280 Generally, the abrasion resistance of the coarse aggregate component is not related to the wear resistance of Concrete Crushing an overview ScienceDirect Topics
