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 …

This paper reports an experimental investigation carried out to establish a mathematical relationship between aggregate crushing value (ACV) and ten percent fines aggregate crushing value (TFV) for some aggregates in Nigeria. Such a mathematical relationship, usually established through regression modelling on data collected, is …

One of the fundamental aspect in assessing aggregate resistance to wearing is the determination of aggregate abrasion value (Aweda et al., 2019). The aggregate abrasion …
