Conclusion of aggregate crushing value test.Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardied conditions.
Crushing, screening and blending are methods used to affect aggregate gradations.However, even following these processes, the material may still require washing to meet a cleanliness specification.Also, screening is impractical for aggregate smaller than no.8 mesh, in which case, hydraulic separation, or classifying, becomes an important.
Classification of aggregate according to nature of formation size wise classification of aggregate.The shape of aggregates is an important characteristic since it affects the workability of concrete.So we should take care about the shape of aggregate.Here we discuss the shape wise classifications of aggregates.
B classification based on source natural aggregates this kind of aggregate is taken from natural deposits without changing their nature during the process production such as crushing and grinding.Manufactured synthetics aggregates this is a kind of man-made materials produced as a main product or an industrial by-product.

1 aggregate sources classification 4.1 natural aggregates natural aggregates consists of rock fragments that are used in their natural state, or are used after mechanical processing such as crushing, washing, and sizing.Some natural aggregate deposits, called pit -run gravel, consist of gravel and sand that can be readily.
After primary crushingreduction the resulting aggregate generally is placed in a large surge pile where the aggregate may be fed into the secondary operation whenever convenient.Care is always taken when building up and loading out surge piles, as this step may be a major source of segregation of material going to the secondary plant.
The heavy weight aggregate is more effectively used as a radiation shield.The concrete that is manufactured with the heavy weight aggregate will have a crushing strength in the range of 20 to 21 mpa.The cement - aggregate ratio will vary from 1.
