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 is the basic raw material for producing …
