  1. Cement and concrete are both mixtures of materials that are used for construction, but there is a big difference between the two. Cement is made up of cement, sand, and gravel, while concrete also includes water and aggregate. Concrete is much stronger than cement because the water reacts with the cement to create a chemical bond.
