How to Choose Quality Coarse Aggregate for Concrete

Sep 11, 2020· The selection of good quality coarse aggregate is essential for the production of concrete that meets the desired strength and durability requirements. Ideal construction aggregate should have a rough surface texture and should be clean, strong, and free from coating and other dirt particles. Coarse aggregates with a size of 20 mm or less are []

Uses of Aggregates in Construction, Roads, Railway and Other

Aggregates are the most mined material in the world. Construction aggregate is a broad category of granular raw material of different sizes (sand, gravel, crushed stone, slag, recycled concrete etc) used in construction. Aggregate can be used in a number of ways in construction. In roads and railway ballast the aggregates are used to resist the overall (static as well as
