Manufacture of Cement- Materials and Manufacturing Process of Portland …
That is Portland cement was first produced by a British stone mason, Joseph Aspdin in 1824, who cooked cement in his kitchen. He heated a mixture of limestone and clay powder in his kitchen, and grind the mixture into powder creating cement, that hardens when mixed with water. The name Portland was given by the inventor as it resembles a stone ...

Portland cement The name Portland cement is used because this powder on mixing with water gives a hard, stone like mass which resembles Portland rock (Leeds city UK). It is widely used as a non-metallic material in construction. It is a composition of calcium silicates, calcium aluminates and small amount of gypsum. Composition of Portland cement:-

An English bricklayer made the first portland cement early in the 19th century by burning powdered limestone and clay on his kitchen stove. With this crude method, Joseph Aspdin of Leeds laid the foundation for an industry that annually processes literally mountains of limestone, clay, cement rock, and other materials into a powder so fine, it ...
