Cement is a complex mixture of compounds that they are rich in lime (CaO) which can react with water to give a durable solid. The reactive compounds, mainly calcium disilicate, calcium trisilicate and tricalcium aluminate, so called "clinker", are formed by heating the ingradients to high temperatures and then suddenly cooling. Homegenous mixing and fine grinding of the raw materials are important aspect of the process.
