Concept 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
The aggregate crushing value is defined as the ratio of the weight of fines passing through specified IS here 236mm sieve to the total weight of sample expressed in percentage W1 Weigh of the total aggregates WaWe W2 Weigh of aggregates passing through 236mm IS sieve
Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions
The aggregate crushing value ACV provides relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load Two versions available 150 standard and 75 mm dia The apparatus comprehend cylinder plunger base plate tamping rod and measure
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 236 mm sieve when a sample of aggregate passing the 132 mm and retained on the 950 mm sieve is subjected to crushing under a gradually applied compressive load of 400 kN 2 APPARATUS 21 An
The value is higher when more percentage of aggregates crush and break into smaller pieces which indicates the aggregates are of a lower quality 2 Aggregate crushing value 45 for aggregates used for concrete for nonwearing surfaces and 25 for wearing surfaces like runways and roadways Discussion
One of the model in which pavement material can fail is by crushing under compressive stress A test is Standardized by IS2386 partIV and used to determine the crushing strength of aggregates The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing load
The Main Discussion Of Aggregate Crushing Value The main discussion of aggregate crushing value aggregate production fines generation during rock crushing the main discussion of aggregate crushing value the energy required to crush rocks is proportional to the amount of new surface area that is created hence a very important percentage of the in fines production during the crushing of single aggregates and aggregates
