Cement, Portland

Portland cement is the most commonly used type of cement in construction. It is named after Portland, England, where it was first produced in the 19th century. Portland cement is manufactured by grinding clinker, a mixture of limestone, clay, and other minerals, to a fine powder. It is known for its excellent binding properties and ability to harden and set when mixed with water. The chemical reaction known as hydration occurs when water is added to Portland cement, resulting in the formation of crystals that contribute to the strength and durability of concrete. Its versatility and widespread availability make Portland cement a fundamental ingredient in various construction applications.
