Though “cement” and “concrete” are often used interchangeably, concrete is actually the final product made from cement. The primary component of cement is limestone. To produce cement, limestone and other clay-like materials are heated in a kiln at 1400°C and then ground to form a lumpy, solid substance called clinker; clinker is then combined with gypsum to form cement.

Investigations have shown that the disadvantages of high proportions of limestone in the cement regarding concrete durability can be compensated to a large extent with a denser microstructure by reducing the w/c ratio.

The argument that PLC could help reduce the environmental impact of concrete has long been proposed based on what was logically deduced from substituting more limestone for less clinker—the ingredient that is most responsible for cement’s CO 2 emissions as well as for the high energy consumption needed during manufacturing—but this study “gives solid numbers to evaluate,” according

There are more than twenty types of cement used to make various specialty concrete, however the most common is Portland cement. Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln.

Limestone, clay, and shale are the three main raw materials used in PC clinker production. They are abundant, both globally and in the United Kingdom (BGS, 2014). Cement plants are generally located adjacent to raw material quarries to minimize transportation costs (BGS, 2014; van Oss & Padovani, 2002).
