For the preparation of economical concrete mix on should use largest coarse aggregates feasible for the structure. IS-456 suggests following recommendation to decide the maximum size of coarse aggregate to be used in P.C.C & R.C.C mix. Maximum size of aggregate should be less than. One-fourth of the minimum dimension of the concrete …

Aggregate is an important raw material in the infrastructure construction industry. Aggregate is divided into fine aggregate (commonly known as sand, with a particle size between 0.15-4.75mm) and coarse aggregate (commonly known as stone, with a particle size between 4.75-9.0mm).. The aggregate material is loose and granular in shape and …

Artificial aggregates (AAs) are man-made construction material, and the properties greatly depend on its manufacturing process (e.g. granulation and hardening) and the raw materials (usually different source of wastes) used. This paper reviews the granulation process and suitable raw materials for each hardening method.

Key Roles of Aggregate in Concrete. The typical concrete mix uses aggregates for a multitude of reasons that significantly influence the lifespan and performance of the resulting concrete. 1. Volume Stabilisation: The aggregate helps to minimise the concrete's shrinkage during drying, reducing the risk of cracking. 2.
