Limestone, diatomaceous earth, and gypsumare the principal materials used to make cement. Limestone for the CaO, diatomaceous earth as a source of finely-divided (i.e. chemically active) silica, and gypsum as a source of calcium sulphate. After firing, these materials are quite chemically active; in the presence of water; and make several complex chemicals in the setting process.
The crystals resulting from the setting are what give the resultant concrete its strength, and since these crystals take some time to form, concrete only approaches its final strength after several weeks. It is a stronger material if kept moist during this period. Excessive water however, weakens the concrete by forming voids as it evaporates. The strongest concrete mixes, such as needed for making concrete pipes, resemble merely damp gravel mix.

What raw matrials are used to make mortar?
The primary raw materials used to make mortar are cement, sand, and water. Cement acts as a binder, sand provides bulk and strength, and water is used to mix and activate the materials. Additional materials such as lime or plasticizers may also be included in the mix for specific properties.
Is coal used to make cement?
Yes, coal is used as a fuel in the cement manufacturing process. It is often used as a source of energy to heat the kiln where the raw materials are processed to make cement. However, efforts are being made to reduce the reliance on coal and shift towards cleaner and more sustainable sources of energy.
What are the raw materials used to make ammonia?
The raw materials used to make ammonia are nitrogen and hydrogen gases. These gases are typically obtained from the atmosphere and natural gas, respectively. The process of producing ammonia from these raw materials involves a chemical reaction known as the Haber-Bosch process.
What is the meaning of clinkerisation temperature?
Clinkerisation temperature refers to the temperature at which raw materials in a cement kiln are heated to produce clinker, which is a hard, nodular material used in cement production. This process involves complex chemical reactions that transform the raw materials into clinker. The temperature typically ranges from 1450 to 1500 degrees Celsius.
What cement contains?
Cement typically consists of limestone, clay, sand, and other materials like iron ore, bauxite, or fly ash. These raw materials are combined and heated in a kiln to form a fine powder known as cement. This powder is then mixed with water to create a paste that hardens and binds together when it dries.
What are raw materials used in ordinary portland cement?

What is a cement factory?
Cement factory is a one in which cement is manufactured in large scale.The cement are manufactured, weighed and packed in the factory.The packed cement bags are stored in godowns and from there to the delivery vehicles.
Is coal used to make cement?
Yes, coal is used as a fuel in the cement manufacturing process. It is often used as a source of energy to heat the kiln where the raw materials are processed to make cement. However, efforts are being made to reduce the reliance on coal and shift towards cleaner and more sustainable sources of energy.

What Sedimentary rock is used in cement?
Limestone is the most common sedimentary rock used in cement production. It is a key ingredient in the production of cement due to its high calcium carbonate content, which reacts with the other raw materials to form the clinker necessary for making cement.
