Portland-limestone cement (PLC) has comparable performance properties to ordinary portland cement but improves the environmental performance of concrete. PLC has been used in the United States on a limited scale in accordance with ASTM C1157 for several years, but it is still considered a relatively new technology.

Limestone, as used by the minerals industry, is any rock composed mostly of calcium carbonate (CaCO 3 ). Although limestone is common in many parts of the United States, it is critically absent from some.

Cement. Cement is made by heating limestone with small quantities of other materials such as clay or sand to 1450°C in a kiln. The resulting ‘clinker’, is then ground with a small amount of gypsum into a powder to make Portland cement. The most common use for Portland cement is in the production of concrete – a composite material
