Shape and size: – Shape and Size of the aggregates decides the cement required for concrete. This means If shape and size of the aggregates are good then concrete will need optimum cement hence concrete will be economical. Maximum size of aggregates reduces the quantity of cement required. Size and shape directly impacts strength of […]

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
