冻融环境下混凝土碳化深度的试验研究
Experimental Study on Concrete Carbonation Depth in Freezing-thawing Circumstance
摘要
Abstract
Factors that influence concrete carbonation in freezing-thawing circumstance are analyzed in this paper. On the basis of test data, the calculation formula for freeze -thaw-carbonation damage coefficient is given by using regression analysis method. And then, a model for predicting carbonation depth of concrete is presented. This model takes freeze-thaw cycle times and water- binder ratio as the main parameter. The results calculated by the model agree well with the spot-data, so it can be used as a reference for predicting the initial corrosion times of steel-bar.关键词
