Learn MoreMar 30, 2020 · The aggregate impact value test is an important test of aggregates. It is done to obtain the resistance and impact of aggregates (stones). In this test a machine is used, which is called impact testing machine.

Learn More1.The difference between the original weight and the final weight of the test sample is expressed as a percentage of the original weight of the test sample. This value is reported as the percentage of wear. Aggregate Abrassion Value = ((A-B)/A) X 100 where, A = weight in gm of oven-dried sample.

Learn MoreThe aggregate whose crushing value is less than 30% can be used for cement concrete road. The aggregate whose crushing value is less than 40% can be used for wearing surface. This test must be done before it comes to road and pavement construction.

Learn MoreThe ‘ 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 .

Learn MoreGrading of aggregate is the particle size distribution of a sample of aggregates on the basis of sieve analysis and sedimentation analysis. The grading of aggregate is plotted in a semi-logarithmic graph to get the particle size distribution curve which is in form of ‘S’.
