Transport Processes in Hydrating Cementitious Coating Systems

Concrete is currently the most widely used material in construction field. A good performance of concrete structures is required for reaching the designed service life. However, the initial scatter in the quality of concrete is unavoidable in practice, possibly resulting from improper design, poor execution, or deterioration due to stresses during the service life of concrete structures (e.g. external load, stress induced by temperature, drying shrinkage or ingress of chemical substances, etc.). A cementitious coating can be used to protect low quality concrete structures against the ingress of aggressive substances, like CO2 and chloride ions, and to extend the service life of the reinforced concrete structures.
