Abstract
Interfacial adhesion between surface coating and cement paste under aggressive environment is the most key properties that responsible the effectiveness of coating on cement paste. The present work is dedicated to an in-depth investigation concerning the temperature influence on the interfacial adhesion degradation between rubber nano-coating and Calcium-Silicate-Hydrate (CSH) paste under harsh environments. Results indicate that a well-distributed fully rubber nano-coating on CSH maintains its impermeability within temperature range of 260–373K for pure water molecules and up to 420K for salty water solution. However, the nano-coated structure loses its impermeability at 380K and 440K in pure water and salty water solution, respectively. The interfacial adhesion between rubber and CSH surface decreases with increasing temperature under both conditions. In addition, the effectiveness of the rubber nano-coating surface weakens due to temperature rising inducing the breaking of the hardest interfacial interatomic cao-c = bonds in both conditions.
