Ordinary Portland cement is the most widely used type of cement. It is produced through a process involving grinding and heating raw materials such as limestone, clay, sand and iron ore. This produces clinker which is then ground together with gypsum. When mixed with water, it undergoes chemical reactions called hydration which causes it to harden …

Portland cement manufacture emits 5–7% CO 2, which is responsible for global warming. Geopolymers minimize CO 2 emission and may be a partial alternative to Portland cement in the building industry. The geopolymer technology gives solution to the utilization of industrial byproducts (waste) containing aluminosilicate phases with little ...
Portland cement is the basic ingredient of concrete. Concrete, one of the most widely used construction materials in the world, is formed when portland cement creates a paste with water that binds with sand and rock to harden. The U.S. industry average portland cement, as found by this study, is 91.4% clinker by weight. Table 1 describes the
