This document gives the determination of aggregate crushing value (ACV) of aggregates. This gives a relative measure of the resistance of the aggregate crushing under the gradually applied compressive load. The method is applicable to aggregates passing a 14,0 mm test sieve and retained on a 10,0 mm test sieve.
Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements. Crushing value of aggregates indicates its strength. Lower crushing value is recommended for roads and pavements as it indicates a lower crushed fraction under load and would give a longer service life and a more ...

It is an essential test for understanding the mechanical properties of aggregates. Here is a step-by-step procedure for conducting the Aggregate Crushing Value test: Equipment and Materials:
DETERMINATION OF AGGREGATE CRUSHING VALUE 2.1 Object - This method of test covers the procedure for determining aggregate crushing value of coarse aggregate. NOTE 1 -The 'aggregate crushing value' gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggre-
getting reproducible results. On the contrary, the aggregate crushing test is simple, rapid and gives fairly consistent results. Application of Aggregate Crushing Test: The aggregate crushing value is an indirect measure of crushing strength of the aggregates. Low aggregate crushing value indicates strong aggregates, as the crushed fraction is low.
The procedure of determining aggregate crushing value can be found in "IS: 2386 (part IV) – 1963 Methods of test for aggregate for concrete Part IV Mechanical properties". According to the IS code, the test is carried out with aggregate retained between sieve of size 12.5mm and 10mm which is then oven dried for 4 hours.
The test aims at looking for the forces required to produce 10% of fine values (i.e. weight of fines aggregates/weight of all aggregates = 10%). This test is very similar to Aggregate Crushing Test in which a standard force 400kN is applied and fines material expressed as a percentage of the original mass is the aggregate crushing value.
Calculation for Aggregate Crushing Value Test. In each test, the ratio of the weight of fines formed to the total sample weight shall be recorded as the percentage. Record the result to the first decimal place. Aggregate crushing value = (W 2 / (W 1 – W 0 )) x 100. Where, W 0 = Weight of empty cylinder with base plate.
This test seeks to determine the amount of force required to produce 10% of fine values, which is expressed as the weight of fine aggregates divided by the weight of all aggregates multiplied by 100 (i.e., weight of fines aggregates/weight of all aggregates x 100 = 10%). This test is similar to the Aggregate Crushing Test (ACV), which applies a ...
