The proportion of sand to coarse aggregate can be readjusted among each other,to accommodate the DLBD properties of locally available material,thus ensuring a cohesive concrete mix. If we are able to form "ball" with arrived fresh concrete we can be sure, we have the right concrete proportion.

AGGREGATE PRODUCTS. The key ingredients of ready mixed concrete and many concrete products are sand, gravel, and crushed stone. CalPortland provides aggregates for a broad range of construction from the simplest applications to projects with specialized high performance characteristics.

Concrete is a material comprised of a number of coarse aggregates (particulate materials such as sand, gravel, crushed stone, and slag) bonded with cement. Cement is a substance that is used to bind materials, such as aggregate, by adhering to said materials, then hardening over time. While there ...

Construction aggregate, or simply "aggregate", is a broad category of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined materials in the world.
