Abstract
This paper studies the freezing-and-thawing durability of cement concrete on the basis of experimental investigation of air-void parameters, which has a significant influence on the durability of concrete. More specifically, this research firstly discusses the effect of air-entraining agent types on the air-void parameters feature, and then a rapid freezing-and-thawing test is conducted to assess the durability of the concrete specimens, so as to observe the relationship between the frost resistance performance evaluation index, which is applied as durability factors in this study, and the air-void parameters of concrete, such as the air void spacing factor and the air content of cement concrete.
