Aggregate Crushing Value Not Exceeding

We are committed to sand and gravel crushing, industrial grinding, ore processing and green building materials, and provide intelligent solutions and mature supporting products.

Aug 27, 2019 Step-11 Sieve the crushed aggregate through 2.36 mm IS sieve and weigh the fraction passing through it to an accuracy of 0.1 gram. This fraction is a measure of loss of material due to crushing. The mean value of two samples, rounded to nearest whole number is taken as the aggregate crushing value. Observation and Calculation.

    Jan 13, 2011 Aggregate Crushing value depends on the shape of agg also. Angular aggregates have a lower ACV, than Irregular or rounded aggregates.If we cut a core out of the same agg (Say in the quarry) and test for compressive strength, will give a higher MPa value. It can be considered as a concrete cylinder or UCS tested in lab. So it is hard to corelate.
