Abstract
The main aim of this study is to investigate the variation of pore structure and frost resistance in mortar subjected to different environmental conditions and for different exposure times. Mortar specimens were prepared by using three types of cement, which are ordinary Portland cement, fly ash cement, and ground granulated blast furnace cement. Various environmental conditions which are drying, wetting, and drying/wetting cycles were applied to specimens in laboratory, after casting mortar specimens followed by initial curing for 4 weeks in water at 20°. The pore structure modification was evaluated by mercury intrusion porosimetry (MIP) method. It was clarified that the pore structure change can be affected by the studied factors, which are exposure drying temperature, exposure drying duration, and cement type. Furthermore, equations which can predict the pore structure changes was derived based on the experimental results.
