Properties Of Aggregates Properties Of Road And Concrete. Aggregate is a collective term for the mineral materials such as gravel, sand and crushed stone, which are used along with binding materials such as bitumen, cement, lime, etc to form compound materials.Properties of aggregate play a vital role in the strength and durability of structures.

When we estimate the concrete quantity, the aggregates will occupy 70 to 75% of the volume.. The classification of aggregates depends on the grain size, density, shape, and geographical origin. So the properties of aggregates will differ based on the classification, and it may influence the mix of the concrete and strength.

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. Moreover it is proved that aggregate's types has the severe effect on physic-mechanical properties of concrete as aggregate covered ...
