- Aggregate Crushing Value Lab Report Discussion
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.

Quality estimation of rock aggregate raw materials is often performed with mechanical tests on aggregates crushed with laboratory crushers. However, standardised mechanical tests are intended for testing products, not raw materials. Different laboratory crushers produce aggregates with varying shape properties [flakiness index (FI), shape …

Ten per cent fines load and ACV tests are two well accepted tests for assessing the mechanical properties of aggregates. While the load producing ten per cent fines is determined in the former test, the amount of fines produced under 40 ton load is given as ACV in the latter test. Both tests are standardised in the U.K. and carried out in …
