Abstract. Both coarse aggregates and fine aggregates are the main constituents of concrete because they not only give the body to the concrete, it also have a significant effect on the fresh concrete based on aggregate’s shape, size, texture, grading and crushing type.

Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions. Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements.

Strength. Although the water / cementious material ratio is an important factor affecting the strength of concrete, the aggregate properties can not be ignored. The aggregate strength is usually not a factor except in lightweight and high strength concrete.
