Aggregates - Portland Cement Association

Aggregates are inert granular materials such as sand, gravel, or crushed stone that, along with water and portland cement, are an essential ingredient in concrete. For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the

Long-term aggregates demand & supply scenarios, 2016-30

crushed rock and marine sand & gravel, to meet future demand. Alternative sources of aggregates, including recycling, secondary materials and imports, have a role to play but are unlikely to be a game changer given their constraints. The share of recycled and secondary aggregates varies between 28% and 37% of overall demand.

PDF Lecture 4. Aggregates

Manufactured lightweight aggregates are produced by expanding some raw materials in a rotary kiln, on a sintering grate, or by mixing them with water. The most common lightweight aggregates are pumice, scoria, expanded shale, expanded clay, expanded slate, expanded perlite, expanded slag and vermiculite.

EFFECTS OF AGGREGATE TYPE, SIZE, AND CONTENT ON CONCRETE

The effects of aggregate type, size, and content on the behavior of normal and high-strength concrete, and the relationships between compressive strength, flexural strength, and fracture energy are discussed. The concrete mixtures incorporate either basalt or crushed limestone, aggregate sizes of 12 mm ('h in.) or 19 mm (:Y. in.), and
