Get Latest PriceCalculation of Aggregate Crushing Value. The crushing value of aggregates is measured in the ratio between the crushed aggregates obtained from the IS sieve 2.36mm 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 ...
Read MoreProcedure to determine Aggregate Crushing Value i The aggregates passing through 12.5mm and retained on 10mm IS Sieve are oven-dried at a temperature of 100 to 110 o C for 3 to 4hrs. ii The cylinder of the apparatus is filled in 3 layers each layer tamped with 25 strokes of a tamping rod. iii The weight of aggregates is measured Weight ‘A’. iv The surface of the aggregates is then ...
Read MoreFor example a graded aggregate of nominal size 12.5 mm means an aggregate most of which passes the 12.5 mm IS Sieve. Because the aggregates are formed due to natural disintegration of rocks or by the artificial crushing of rock or gravel they derive their many of the properties from the parent rocks. These properties are chemical mineral composition petrographic description hardness ...
Read MoreTake the aggregate out of cylinder and sieve them through 2.36 mm IS sieve. Weight this fraction passing through it to an accuracy of 0.1 gm. This fraction is a quantity of loss of material due to crushing. Note down the observations in the proforma then compute the aggregate crushing value. The mean of two observations rounded to nearest whole number is reported as the Aggregate crushing ...

Read MoreThe standard aggregate impact test shall be made on aggregate passing a 14.0 mm BS test sieve and retained on a10.0 mm BS test sieve. If required or if the standard size is not available smaller sizes may be tested but owing to the non-homogeneity of aggregates the results are not likely to be the same as those obtained from the standard size. In general the smaller sizes of aggregates will ...
