Dec 26, 2019· The aim of aggregate impact test is to determine the relative measure of the resistance of aggregate to sudden shock or impact in which in some aggregate differs from its resistance to a slowly applies compressive load The property of a material10% Fine Value: All aggregates are required to meet a minimum strength valve, as defined by the 10% value test This and other specifications ensure that only the highest quality materials are being used on construction projects Test Method: IS: 2386 (P4)1963 Alkali Aggregate Reactivity: Alkaliaggregate reaction is the term mainly referred to a reaction Continue reading "Aggregate Testing"Aggregate Test | Aggregate Lab Test | Sigmatest

The aggregates should therefore have sufficient toughness to resist their disintegration due to impact This characteristic is measured by impact value test The aggregate impact value is a measure of resistance to sudden impact or shock, which may differ from its resistance to gradually applied compressive load Procedure of Aggregate Impact TestAGGREGATE CRUSHING VALUE 1Objective The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load With aggregate of aggregate crushing value 30 or higher, the result may be anomalous, and in such cases the ten percent fines value should be determined insteadAGGREGATE CRUSHING VALUE

The aggregate shall be taken as in the case of crushing strength value test ie, the aggregate should pass through 125 mm IS sieve and retained on 10 mm IS sieve It should be oven dried at 100°C to 110°C for four hours and then air cooled before testAs per the definition given in the ‘IS: 2386 (Part III) – 1963’, (Indian Standard Methods of Test for Aggregates for Concrete – Specific Gravity, Density, Voids, Absorption and Bulking), the specific gravity of coarse aggregates is the weight of the aggregates dried to constant weight in an oven at 100°C divided by its absolute volume including the natural voids within the aggregateSpecific Gravity of Coarse Aggregates: Its Importance
