Crushing Value of Aggregate The crushing value of aggregates is rather insensitive to variation in strength of weaker aggregates For this reason, a simple test known as 10 percent fine value is introduced When the aggregates crushing value become 30% or higher, the results are likely to be inaccurate Aggregate Crushing Load (Source: TheTheory Aggregate Crushing Value Aggregate crushing value test nptel in swedenthe 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 testtheory aggregate crushing value test of aggregate

Theory Aggregate Crushing Value Calculation of Aggregate Crushing Value 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 resultsaggregate crushing value test aim, aggregate crushing value test aim aggregate crushing value test aim theory of aggregate impact value test 11/3/2011 · aggregate crushing value test AIM (i) Go to Product Center AGGREGATE CRUSHING VALUE TEST ( IS : 2386 – PART – 4, AGGREGATE CRUSHING VALUE TESTtheory aggregate crushing value test of aggregate

Determination Aggregate Crushing Value Theory The aggregate crushing value ACV of an aggregate is the mass of material, expressed as a percentage of the test sample which is crushed finer than a 2,36 mm sieve when a sample of aggregate passing the 13,2 mm and retained on the 9,50 mm sieve is subjected to crushing under a gradually appliedThis test is very similar to Aggregate Crushing Test in which a standard force 400kN is applied and fines material expressed as a percentage of the original mass is the aggregate crushing value Granular subbase is subjected to repeated loadings from truck typ The stress level at the contact points of aggregate particles is quite hightheory aggregate crushing value pourvousbrasschaatbe
