Objective and Significance: – The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggregate of aggregate crushing value 30 or higher, the result may be anomalous, and in such cases the ten percent fines value should be determined instead. Crushing value […]

Objective and Significance: – Impact value of the aggregates is useful to understand the strength of the concrete against impact. If aggregates are used in road construction, then are subject to get impact due to heavy road traffic. This causes crushing the aggregates and hence aggregates impact value is important to find out. The aggregate

Objectives and Significance:- Water absorption gives an idea on the internal structure of aggregate. Aggregates having more absorption are more porous in nature and are generally considered unsuitable, unless found to be acceptable based on strength, impact and hardness tests. Aim: – Aim of this test is to determine the water absorption of coarse aggregates.
