Method B1
This document describes the procedure for determining the aggregate crushing value (ACV) of aggregate materials. The ACV test involves crushing a sample of aggregate between 9.5mm and 13.2mm under a gradually applied 400kN load. The percentage of material crushed finer than 2.36mm is calculated and reported as the ACV. The test can be performed dry or after soaking …

Crushing Value of Aggregate
The crushing value of aggregates is rather insensitive to variation in strength of weaker aggregates. For this reason, a simple test known as 10 percent fine value is introduced. When the aggregates crushing value become 30% or higher, the results are likely to be inaccurate. Aggregate Crushing Load (Source: IS 2386(Part 4):1963) The aggregates ...
