Applications        :    Aggregate is an essential ingredient of concrete. The purpose of aggregates in concrete is
  • To provide a rigid structure
  • To reduce the shrinkage and cracking
  • Concrete aggregate is used in many structures and substructures e.g. different elements of a Building, bridges, foundations
  • The smaller the aggregate size the greater its surface area and the more binding material (cement) will be required, resulting in a higher cost
  • The greater the aggregate size the larger will be the voids, resulting in wastage of binding material(cement)

Hence a mixture of coarse and fine aggregate is used in concrete to avoid both these problems.

20 mm stone aggregates are used RCC works. They act as fillers in the concrete. 20 mm stone should be in cube shape and hard in nature. It should not have flakes and other impurities in it.
  • Due to the relatively high hydraulic conductivity value as compared to most soils, aggregates are widely used in drainage applications such as foundation and French drains, septic drain fields, retaining wall drains, and road side edge drains
  •  Aggregates are also used as base material under foundations, roads, and railroads. In other words, aggregates are used as a stable foundation or road/rail base with predictable, uniform properties (e.g. to help prevent differential settling under the road or building), or as a low-cost extender that binds with more expensive cement or asphalt to form concrete
