Mechanical And Durability Properties Of Concrete Under Low Temperatures, Yao Wang
Civil Engineering Graduate Theses & Dissertations
Frost attack can heavily damage concrete materials and concrete structures. Therefore, it is important to predict the service life of concrete structures considering the effect of the deterioration process. A theoretical model based on Mori-Tanaka micromechanics method was developed to estimate the deterioration of elastic properties of concrete under low temperatures. The model took into account a continuous pore size distribution for cement paste, freezing temperatures with different pore sizes, and damage development in cement paste. The model was able to characterize the stiffening effect due to the formation of solid ice and the weakening effect of the damage development ...
