Cement is an ingredient of concrete. concrete is a mixture of water, aggregates i.e. small stones, sand and portland cement. portland cement is not a brand name but rather a generic term for the type of cement used in most concrete. the cement and water harden and bind the aggregates into a solid mass over time through a process called hydration.
