AGGREGATE CRUSHING STRENGTH TEST Theory and Scope: This is one of the major Mechanical properties required in a road stone. The test evaluates the ability of the Aggregates used in road construction to withstand the stresses induced by moving vehicles in the form of crushing.
The strength of coarse aggregate is assessed by aggregate crushing test, the aggregate value provide the relative measure of resistance to crushing under gradually applied compressive load. Lower the aggregate crushing value greater will be the "resistance to crushing under gradually applied compressive load".

Aggregate is a term for any particulate material. Includes gravel, crushed stone, sand, slag, recycled concrete and geosynthetic aggregates.
The determination of aggregate crushing strength is an important test in your civil engineering lab.You know that aggregates are the one the basic unit of building materials.Aggregates are used in several construction processes such as in concrete, road construction etc..
Abstract: This paper studied the effect of aggregate properties on the crushing strength of concrete. In order to achieve the study objective, three types of coarse aggregates, brick khoa, shingles stone, and black stone were used to test.

Effect of aggregate type on Compressive strength of concrete Abdullahi. M International Journal of Civil and Structural Engineering Volume 2 Issue 3 2012 792 normal and high-performance concrete (Özturan, and Çeçen, 1997). The research work
The Cold Crushing Strength (CCS) represents the ability of a product to resist failure under compressive load at room temperature. It has an indirect relevance to refractory performance, and is used as one of the indicators of abrasion resistance. The higher the CCS of a material is the greater should be the resistance to abrasion.

The crushing strength of concrete, determined by breaking a cube, and often called the cube strength, reaches values of about 3 tons per square inch, that of granite 10 tons per square inch, and that of cast iron from 25 to 60 tons per square inch.

Compressive strength test, mechanical test measuring the maximum amount of compressive load a material can bear before fracturing.The test piece, usually in the form of a cube, prism, or cylinder, is compressed between the platens of a compression-testing machine by a gradually applied load.
For adsorbents and catalysts of a similar phase composition, the impact strength factor is proportional to the crushing strength, though various materials of the same crushing strength exhibit different impact strength values (Fig. 11). The long-term strength appears to be most sensitive to structural and composition features of materials .
Aggregate Crushing value depends on the shape of agg also. Angular aggregates have a lower ACV, than Irregular or rounded aggregates.If we cut a core out of the same agg (Say in the quarry) and test for compressive strength, will give a higher MPa value. It can be considered as a concrete cylinder or UCS tested in lab. So it is hard to corelate

The Effect of Aggregate Properties on Concrete Concrete is a mixture of cementious material, aggregate, and water. ... A smooth surface can improve workability, yet a rougher surface generates a stronger bond between the paste and the aggregate creating a higher strength.
This work deals with the effect of the contact location distribution on the crushing of granular materials. At first, a simple drop weight experiment was designed in order to study the effect of the location of three contact edges on the fracture pattern and the strength of a model cylindrical particle.
