The Determination of The Aggregate Crushing Value PDF
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 …

Determine Aggregate Crushing Strength
Procedure The aggregate sample: The material for the standard test consists of aggregates sized 10.0 mm to 12.5 mm.The aggregates must be in a surface dry condition before testing. The aggregates may be dried by heating at 100 oC – 110 o C for not more than 4 hours and cooled to room temperature before testing, if necessary.
