    Portland-Limestone Cement - Portland Cement Association

    Cement is made by grinding clinker—the main energy intensive ingredient—to a fine powder. Producers know that replacing some of the clinker in portland cement with ground limestone offers benefits, the most important being that it reduces the embodied CO2 of the cement.

    Difference Between Clinker and Cement Compare the ...

    Oct 23, 2011  The key difference between clinker and cement is that clinker appears as marble-like nodules, whereas cement is a very fine powder.. Earlier, people did not have sophisticated homes; therefore, they used simple things found in the environment to build houses. But today there are many advanced materials and equipment, which assist in constructions.

    Cement — IXRF Systems

    Portland cement, the most common type of cement, is made by mining, and then grinding raw materials that include limestone, clay, and bauxite to a fine powder, called raw meal. This is then heated in a rotating cement kiln. This process produces clinker: rounded nodules between 1mm and 25mm across.
