Study on the Anti-Spalling Performance of Concrete Pavement in Cold Area
In accordance with the spalling of concrete pavement in cold area, this paper puts forward a concrete proportion after making plenty of experiments, which is carried out by adding flyash, silicon powder, air entraining and water reducing admixture with different contents and proportions to normal concrete, using flexure strength, compression strength, impermeability and frost resistance as evaluating indicators. The concrete proportion reaches high flexure strength and compression strength, good impermeability and frost resistance. According to the experimental results and economic analysis, it is shown that the concrete proportion can effectively reduce spalling of concrete pavement. Therefore, it has good use value and it is promising with a good prospect of application.
