Aggregate crushing value test | Step by Step

This test is repeated once or twice and the average crushing value of the aggregate is determined. The average crushing value in the different tests is the actual crushing value of aggregate. Important points to remember. It is recommended that the crushing value of aggregate should be less than 30%. If it is more than 30 % then 10% finer

9 Corrugated Box Testing Methods to Ensure

In the Edge Crush test, force is applied to one side of the box, perpendicular to the ridges, until the box gets crushed. In the Ring Crush test, a ring cut out from the box is used to test the same. While in the flat crush test, excessive force is applied on one side. The results of the Edge Crush test are measured in pounds per lineal inch of load-bearing edge but represented as ECT. ECT
