properties of concrete–setting and hardening, strength, and dimensional stability–depend primarily on calcium silicate hydrate. It is the heart of concrete. As concrete hardens, its gross volume remains almost unchanged, but hardened concrete contains pores filled with water and air that have no strength.

• The rate of hardening of cement depends on the chemical and physical properties of the cement, the curing conditions and the water/cement ratio. Soundness: • Soundness is a physical property of cement paste, which determines the ability of the cement paste to retain its volume after setting is completed.
