Concrete is the most commonly used building material today. What is it made of? What is cement? How are they produced? The short video explains.
Cement is a binding material that is commonly used in construction. It is a fine powder, typically gray in color, made from a mixture of limestone, clay, and other minerals. When mixed with water, cement undergoes hydration, which hardens and binds together aggregates such as sand and gravel, forming concrete.
