Crushing Strength Of Coarse Aggregate Test

Compression test - SlideShare

06.08.2014· B) COMPRESSION TEST PRINCIPLE: Concrete is a homogeneous mixture of cement, sand and coarse aggregate with adequate quantity of water. Since all the physical properties of concrete are directly or indirectly related to the crushing strength, this is the important of all the properties of concrete. The following are the factors, which influence the compressive strength of concrete. i) Water

Crushing strength of road stone may be determine either on aggregates or on cylindrical specimen cut out of rocks. The two tests are quite different not only in the approach but also in the expression of the results. Aggregate used in road construction, should be strong enough to resist crushing under traffic wheel loads. If the aggregates are weak the stability of the pavement structure is
