The phase 5 (5 Mg(OH) 2.MgCl 2.8H 2 O) is the source for strength and hardening of Sorel cement. At the atomic scale, phase 5 formation can be explained by the adsorption of the atoms Mg 2+ , OH − and Cl − when mixing MgO and MgCl 2 .6H 2 O on the surface of MgO.

Sorel cement-based materials with new additions have become the focus of research. The addition of polypropylene fibres to Sorel cement significantly affects the reduction of shrinkage cracks and micro cracks (Bensted 1989). The use of additives is a simple way of minimizing water absorption and permeability in Sorel cement.
