Concrete is made by mixing cement, water, sand, and gravel.

Concrete is a building material that is commonly used in construction. It is made by combining cement, water, sand, and gravel. The process of making concrete involves mixing these ingredients together to form a cohesive mixture. The cement acts as a binder, holding the other components together, while the water helps to activate the cement and make the mixture workable. The sand and gravel provide strength and stability to the concrete mixture.
