What is Cement?
Cement is a fine powder that is the principal strength-giving and property-controlling component of concrete. People often confuse cement with concrete.
Concrete is a mixture of cement, aggregates, and water that hardens to form a building material used for everything from sidewalks, homes, and roads to bridges, dams, and skyscrapers.
Cement is to concrete as flour is to cake. Concrete is second only to water as the most consumed substance on Earth, with almost one ton of it being used for each human every year.
