    Aggregate in Concrete - The Concrete Net

    If there is a deficiency in a locally availe fine aggregate, concrete may benefit from the addition of air entrainment, additional cement, or a supplemental cementitious material () to address these shortcomings. Broad coarse-aggregate gradation ranges are listed in Table 2 of ASTM C 33.

    Coarse aggregates are any particles greater than 0.19 inch, but generally range between 3/8 and 1.5 inches in diameter. Gravels constitute the majority of coarse aggregate used in concrete with crushed stone making up most of the remainder. Natural gravel and sand are usually dug or d from a pit, river, lake, or seabed.

    OverviewHistoryModern productionRecycled materials for aggregatesConstruction 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. Aggregates are a component of composite materials such as concrete and asphalt concrete; the aggregate serves as reinforcement to add strength to the overall composite material. Due to the relatively high hydraulic c

    The Effect of Aggregate Properties on Concrete

    Aggregate is classified as two different types, coarse and fine. Coarse aggregate is usually greater than 4.75 mm (retained on a No. 4 sieve), while fine aggregate is less than 4.75 mm (passing the No. 4 sieve). The compressive aggregate strength is an important factor in the selection of aggregate.
