Portland cement can be made by following two different processes – a dry one and a wet one. Joseph Aspdin first made portland cement in his kitchen stove in England in the 19th century. Lime and silica make up approximately 85% of portland cement. The materials that are commonly used are limestone, shells, chalk, shale, clay, slate, silica sand, and iron ore.
Energy represents 20% to 40% of the total cost of cement production. The production of cement clinker from limestone and chalk by heating limestone to temperatures above 950°C is the main energy consuming process. Portland cement, the most widely used cement type, contains 95% cement clinker.
