The test requires samples of the aggregate to be subjected to standard load crushing conditions. Multiple layers of presieved materials are tamped 25 times before a 40-ton load is applied at a rate of 4 tons per minute. The crushed aggregate is then sieved, weighed, and compared to the original total weight to provide an aggregate crushing ...

Aggregate Crushing Value (ACV) – this is the measurement of the resistance of aggregate to crushing by compressive force. A test specimen (10-14mm) is compressed (up to 400 kN) and the proportion of material passing 2.36 mm is the ACV (mean value of two tests). The higher the value the weaker the aggregate.

A holistic understanding of the material's properties necessitates an amalgamation of findings from multiple tests. In conjunction with the TFV test, insights from assessments such as the Aggregate Crushing Value (ACV) and aggregate impact value (AIV) tests are indispensable. This synergistic approach provides a comprehensive …

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 …
