Method B1 The Determination Of The Aggregate

Determination Of Aggregate Crushing Value Aggregate to crushing under a gradually applied compressive load crushing value is a measure of the strength of the aggregate the aggregates should therefore have minimum crushing value 3 apparatus the apparatus of the aggregate crushing value test Aggregate Crushing Value ratio of the weight of fines formed to the total sample weight in each test shall be expressed as a percentage the result being recorded to the first decimal place aggregate crushing value ba x 100 where a weight of ovendried sample b weight in g of fraction passing through 236 mm is sieve aggregate crushing value test Aggregate Crushing Value Test Step By Step Procedure This test is repeated once or twice and the average crushing value of the aggregate is determined the average crushing value in the different tests is the actual crushing value of aggregate important points to remember it is recommended that the crushing value of aggregate should be less than 30 Aggregate Crushing Value Test Determine Aggregate 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 aggregates are subjected to a specified load under standardized Aggregate Crushing Value Test Significance Test 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 results the crushing value of aggregate

Method B1 The Determination Of The Aggregate 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 77 Aggregate Crushing Value And 10 Fines Value Number report the mean as the aggregate crushing value unless the individual results differ by more than 007 times the mean value in this case repeat the test on two further specimens calculate the median of the four results to the nearest whole number and report the median as the aggregate crushing value a data sheet is given as form 771 Aggregate Crushing Value Test Determine Aggregate 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 Aggregate Crushing Value Test For Ppt 201055 aggregate crushing value test provides strength of aggregates for resistance against crushing under loads and is used for roads and pavements construction crushing value of aggregate ppt crushing value of aggregate ppt offer any sizereduction requirements including quarry aggregate and different kinds of minerals
