Procedure for crushing strength of aggregate. Before testing, the aggregate should be in surface dry can achieve the dry condition of aggregate by placing aggregates in an oven for 4 hours at 100degree Celcius. The aggregates passing through 12.5mm and retained on 10mm IS sieves are selected for finding aggregate crushing strength.

A Concrete Strength Testing Technician is an individual who has demonstrated the knowledge and ability to properly perform, record, and report the results of four basic laboratory procedures related to the determination of concrete compressive and flexural strength.

Concept and significance of the Aggregate crushing value test. The aggregate crushing value test gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Aggregate crushing value is defined as the percentage by weight of the crushed or finer material obtained when the test aggregates are subjected to a specified load under

Compressive strength of concrete is the Strength of hardened concrete measured by the compression test. The compression strength of concrete is a measure of the concretes ability to resist loads which tend to compress it. It is measured by crushing cylindrical concrete specimens in compression testing machine.
