Cement is the chief ingredient in cement paste – the binding agent in portland cement concrete (PCC).It is a hydraulic cement that, when combined with water, hardens into a solid mass. Interspersed in an aggregate matrix it forms PCC. As a material, portland cement has been used for well over 175 years and, from an empirical perspective, its behavior is wellunderstood.
