2018-4-26 In road construction, the quality of aggregates is assessed by the crushing strength of aggregates.For higher quality of roads, the aggregate should possess low aggregate crushing value. Here I am going to teach you how to determine the crushing strength of aggregates.First, let us check what are the various apparatus needed for this experiment.

The aggregates crushing value test should be performed as per IS code 2386 Part IV. First, fill the sample aggregate with one-third of the cylindrical measure in three layers. Each layer should be tamped 25times freely. After filling the sample aggregate, weigh and record it as W1. Now fill the aggregate in the mould along with the plunger on top.

AGGREGATE CRUSHING VALUE 1.Objective The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggregate of aggregate crushing value 30 or higher, the result may be anomalous, and in such cases the ten percent fines value should be determined instead.

6. Impact, 10% Fines & Crushing Tests If the percentage fines exceeds 30, the result may be anomalous as the broken pieces of aggregate will tend to fill the voids and prevent further crushing. In this case, the Ten Percent Fines Test is more appropriate. Some countries, e.g., Australia and New Zealand, only use the latter test.
