| Abstract: | Based on analysis of freeze-thaw resistance and durability of cement concrete, this paper puts forward the principle of the road and bridge cement concrete′s durability grade and freez-thaw resistance grade, studies the cement concrete′s freezing resistance mechanism under the different environmental conditions, analyzes the main physical and mechanical properties of highly freeze-thaw resistance cement concrete. In the end, this paper puts forward the mixing design method and preparation technology of concrete which can effectively improve the freeze-thaw resistance and durability of cement concrete. |
