The most common type of cement used around the world that is manufactured from limestone and clay is:

Portland cement
White cement
Masonry cement
Sulphate resisting cement

The correct answer is: Portland cement

Portland cement is the correct answer because it is the most commonly used type of cement around the world. It is produced from a mixture of limestone and clay which are crushed, then heated in a kiln to form a clinker. This clinker is then ground with a small amount of gypsum to produce Portland cement. White cement (option B) is a specialized type of cement that is used for aesthetic purposes due to its white color. Masonry cement (option C) is a blended hydraulic cement composed of Portland cement, other cementitious materials, and a fine mineral that is used in masonry construction. Sulphate resisting cement (option D) is a type of cement that is designed to resist sulphate attacks and is used in areas prone to such conditions.
