Concrete is defined in ASTM Terminology Relating to Concrete and Concrete Aggregates (C 125) as “a composite material that consists essentially of a binding medium within which are embedded particles or fragments of aggregate; in hydraulic- cement concrete, the binder is formed from a mixture of hydraulic cement and water.” Hydraulic-cement concretes are those most widely used in the United States and worldwide. Hydraulic cement is defined in ASTM Terminology Related to Hydraulic Cement (C 219) as “a cement that sets and hardens by chemical interaction with water and that is capable of doing so underwater.” Portland cement is the most important hydraulic cement. It is produced by pulverizing portland cement clinker, consisting essentially of hydraulic calcium silicates, usually by intergrinding with small amounts of calcium sulfate compounds to control reaction rates. It may be used in combination with one or more supplementary cementitious materials, such as fly ash, ground granulated blast furnace slag (referred to as “slag” in the remainder of this chapter), silica fume, or calcined clay.
