7 Lab Tests on Aggregates to Make Better .

This percentage is known as a crushing value of aggregate. This percentage should not exceed 30% of the total weight of aggregate taken for the test. The aggregate crushing value test result should not be more than 30 % for the concrete used for roads and pavements and, in case of other structures; it may be permitted up to 45%.

aggregate crushing value test in wikipedia

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.

Aggregate Properties - The Concrete Portal

E values of aggregate very different from paste will cause a mismatch at the interface, and this region can thus get prone to cracking. Figure 3 shows a typical pattern of crack development in concrete subjected to compressive loading. The interface cracks form first, and then grow outwards into the mortar. Thus the best concrete aggregates are those with E values in the range of the paste ...
