Aggregate Crushing Value Test Determine Aggregate
Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements Crushing value of Depending on the type of parent rock gives the different crushing value of aggregate as a compressive strength varying from a minimum of about 45 MPa to a maximum of 545 MPa It is a fact that parent rock compressive strength Aggregate Crushing Value Test Crushing Value Of 17/05/2019 The ‘ aggregate crushing value test ` gives a relative measure of the resistance of an aggregate to crushing under a gradually applied Aggregate Crushing Value Test – Determine Aggregate
How to Determine the Aggregate Crushing Strength Value in
26/04/2018 Procedure for crushing strength of aggregate Before testing, the aggregate should be in surface dry conditionYou can achieve the dry condition of aggregate by placing aggregates in an oven for 4 hours at 100degree Celcius The aggregates passing through 125mm and retained on 10mm IS sieves are selected for finding aggregate crushing strength18/07/2021 The crushing value indicates the strength of aggregates The aggregates used for quality pavement should be strong enough to withstand the crushing under roller and traffic loads ie Low crushing value A lower crushing value indicates a lower crushing fraction under a specific load and would give a better result, longer service life and economic performance Crushing Value Test of Aggregates Importance, Procedure The crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 236mm and the weight of the dried aggregate sample At least three samples should be tested from the same batch and average value to get accurate results The crushing value of aggregate = (W2/W1) x 100 Lab ReportAggregate Crushing Value Test Significance Test
