There are six different types of cement with specific defining behaviours and chemical compositions. Below we look at each type and what makes them unique. Type I Ordinary Portland Cement OPC. This is a general purpose cement with no special properties.Portland cement gets its strength from chemical reactions between the cement and water. The process is known as hydration. This is a complex process that is best understood by first understanding the chemical composition of cement. Manufacture of cement Portland cement is manufactured by crushing, milling and proportioning the following materialsTypes of cement. Cement is a binding material used to bind different type of construction materials together. It is formed from argillaceous, siliceous, calcareous etc. By twisting this internal mix ratio and by altering the chemical inputs, special types of cement can be produced according to the needs.Type 1 cement, also known as mortar, is commonly used to adhere cinder blocks or bricks in construction. The final three types of mortar are known as the air-entrained cements, because they have microscopic air bubbles added to their mixtures to increase the durability of the concrete.
