materials other than crushed concrete. Currently, only the use of coarse aggregate derived from construction or demolition waste is recommended for use in new concrete construction. • The characteristic of recycled aggregates could be different by its parent concrete because the
Aggregate size and shape vary, too. The size, which can range anywhere from 3/8 inch to 2 inches or more in diameter, largely determines the depth of exposure. Aggregate shape affects the surface pattern and texture. Rounded aggregates provide the best coverage and a smoother surface while angular aggregates add more texture and dimension.
Properties of Aggregates and its Values for use in Construction. Properties of aggregates such as bulk density, specific gravity, voids, water absorption and its values are presented in this article.
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.
Typically, coarse aggregate sizes are larger than mm (5 mm in British code), while fine aggregates form the portion below mm. A maximum size up to 40 mm is used for coarse aggregate in most structural applications, while for mass concreting purposes such as dams, sizes up to 150 mm may be used.
