General Classification of Aggregates - Pinoy Builders

Aggregates, as defined in the field of construction and civil engineering, are granular materials of mineral composition, used either in combination with a binding medium to form concrete, motar, and plaster. It is also used for various infrastructure projects and even as a material for decorative pieces. Generally, aggregates may be broadly termed as either natural or artificial.
