Abstract

The thermal properties of cement-based materials have gained more attention not only for the
thermal analysis but also for the application of Non-Destructive Tests for building, bridge and other structures.
Presence of chloride ions in pore structure was also found to affect thermal properties of concrete. This paper
aims to study effects of chloride content on thermal properties of concrete. Specimens were submerged in
sodium chloride solution for different period of time. Then, they were subjected to the heating test. It was found
out that temperature of specimens with presence of chloride ions in pore solution increased faster compared to
specimens without chloride contaminations. As the amount of chloride content in pore structure increased,
concrete temperature also rose faster. The results obtained from this study can be used to accurately estimate
thermal properties of concrete so that thermal analysis and application of Non-Destructive Tests such as Infrared
Thermography can be effectively implemented.
