7 Lab Test on Aggregates that we Use in Concrete Construction!

The crushing test on aggregate gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. If the aggregate crushing value is less than 10, it signifies an exceptionally strong aggregate. Whereas, if the crushing value is 35 or above, it would normally be considered as weak aggregates.

A Simple Guide to Concrete Cube Testing - qemsolutions

Cube Testing The cubes are generally tested at 7 & 28 days unless specific early tests are required, for example to remove a concrete shutter safely prior to 7 days. Usually 1 cube will be tested at 7 days and 2 cubes at 28 days, however this may vary depending of the requirements, check the design first.
