Read MoreAggregate Crushing values is a relative resistance of aggregates to crushing under gradually applied compressive load In situations, when aggregate value 30 or higher the result may be a mistake and in such cases, the ten percent fines value should be determined and used instead.
Read MoreAGGREGATE CRUSHING VALUE. This test helps to determine the aggregate crushing value of coarse aggregates as per IS 2386 Part IV 1963. The apparatus used is Cylindrical measure and plunger, Compression testing machine, IS Sieves of sizes 12.5mm, 10mm and 2.36mm. Procedure to determine Aggregate Crushing Value.
Read More7.7 Aggregate Crushing Value and 10 Fines Value 7.7.1 Aggregate Crushing Value ACV 7.7.1.1 Introduction. One of the requirements, for the suitability of aggregates for construction, is the ability of the aggregate to resist crushing. The Aggregate Crushing Value gives a relative measure of the resistance of the aggregate to crushing under a
Read MoreConcept and significance of the Aggregate crushing value test. The aggregate crushing value test gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Aggregate crushing value is defined as the percentage by weight of the crushed or finer material obtained when the test
Read MoreJan 23, 2018 Aggregate Impact Value test determines the Aggregate Impact Value AIV of aggregates which provides a relative measure of the resistance of an aggregate to sudden shock or impact. Resistance of the aggregates to impact is termed as toughness.
Read MoreThis Apparatus is used to determine aggregate impact value of coarse aggregate. The hammer of the tester fall freely from 380 mm height on coarse aggregate for 15 times15 crushed aggregate removed from the cup ,then sieved and weighed. The ratio of the weight passing 2.36mm sieve and weight of oven dried sample is Aggregate Impact value.

Read MoreThe aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement, aggregates possessing low aggregate crushing value should be preferred.
Read MoreAggregate Impact Values, AIVs, below 10 are regarded as strong, and AIVs above 35 would normally be regarded as too weak for use in road surfaces. Aggregate Impact Values and Aggregate Crushing Values are often numerically very similar, and indicate similar aggregate strength properties. Aggregate Impact Value Test Specifications
Read MoreThe aggregate 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 the measure of resistance to sudden impact of shock, which may differ from its resistance to gradually applied compressive load. Equipments
Read MoreApr 10, 2012 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
Read MoreJul 16, 2014 Aggregate impact value test also gives an indirect indication of the strength characteristics of aggregate. Aggregate impact value of a sample also depends on the shape factors such as flakiness index and elongation index of the aggregates. It has been found that for majority of aggregates, the aggregate crushing value and aggregate impact
