Portland cement is a general term used to describe a variety of cements. Because they are hydraulic cements, they will set and harden by reacting chemically with water through hydration. Hydraulic cements are the binding agents in concretes and most mortars and are thus common and critically important construction materials.

The construction of a repository for the geological disposal of radioactive waste will utilize cement-based materials. Following closure, resaturation will result in the development of a highly alkaline porewater. The alkaline fluid will migrate and react with host rock, producing a chemically disturbed zone (CDZ) around the repository. To understand how these conditions may evolve, a series ...
