2.2.6 Aggregate Impact and Crushing Values Aggregate impact value gives relative measure of the resistance of an aggregate to sudden shock or impact and aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. The aggregates were tested in a surface dry 777

Shell Thicknessmm 36 3.5 Water Water to be used in the concrete work should have following properties It should be free from injurious amount of oil, acids, alkalis or other organic or inorganic impurities.
Book NowAggregate Crushing Value test helps to determine the aggregate crushing value of coarse aggregates according to BS 812, Part 1101990. These values are shown in table 3.1 aggregate crushing value of the discarded aggregate is 28.91 while the natural aggregate is 23.63 which implies that the discarded
Book NowThis is mainly attributed to the less stiffness value of OPS aggregate compared to gravel. The development of values of concrete is influenced by the type of coarse aggregate, type of cement, wc ratio of the mix, aggregate size, and curing age . Generally the modulus of elasticity of concrete depends on the stiffness of coarse aggregate.
