Properties of aggregates Physical properties Chemical

Strength of the aggregates simply means compressive or crushing strength of the aggregate It is represented by aggregate crushing value ACV is the quantified resistance provided by aggregates to the progressively applied compressive/crushing loads This is generally determined for coarse aggregates

Types of Testing for Aggregates Structural Guide

TESTING OF AGGREGATE CRUSHING VALUE Aggregate crushing value is an indicator of the crushing resistance of the aggregates when a compressive load is increased It is tested in accordance with BS 812 110 1990 and aggregate passing a 14mm test sieve and retained on 10mm sieve are considered for the testing The allowable range is 17 41

Polished Stone Value Test Procedures and Equipment

The percentage mass of fines passing a BS test sieve formed in the test is known as the aggregate impact value AIV higher values are given by weaker materials For the majority of aggregates the impact value and the crushing value are similar but brittle materials such as flints yield impact values which are about 5 units higher than
