The processes involved in cement production can be summarized in the flowchart shown in Fig. 65.3. Right from mining or raw materials to packaging of cement, energy is being used and carbon dioxide is being emitted into the atmosphere.
The principal reaction of this stage is as follows: Ca2SiO4 + CaO → Ca3SiO5 The liquid formed both acts as a solvent of ion exchange between the solid phases and draws the reactant particles together by surface tension. The powdery or granular mixture quickly solidifies into spherical nodules of clinker. Cooling and storing

The main raw materials for cement production are limestone and marl. The stones are quarried, crushed and ground to a raw meal. Before the raw meal is fed into the kiln, it passes a cyclone...
Classification Code (SCC) for portland cement plants with wet process kilns is 3-05-006, and the six-digit SCC for plants with dry process kilns is 3-05-007. Portland cement accounts for 95 percent of the hydraulic cement production in the United States. The balance of domestic cement production is primarily masonry cement. Both of these
combustion and cement production. The United States is the world's third largest cement producer, with production occurring in 37 states. Cement production is not only a source of combustion-related CO2 emissions, but it is also one of the largest sources of industrial process-related emissions in the United States. Between 1990 and
