Study on Frost Resistance of Concrete Used in Pavement of Northeast China
According to the cycles of freezing and thawing frequently happened during early spring and late autumn in northeast china, this paper studies on the frost resistance of concrete using in highway pavement. Making experiments by adding flyash, silicon powder, air entraining and water reducing agent to normal concrete with different proportions and using flexure strength, compression strength and mass loss rate of concrete as evaluating indicators, a reasonable and economic concrete proportion is determined, which reaches high flexure strength and compression strength, good frost resistance. On the bases of the experimental results and economic analysis, it is shown that the concrete proportion can effectively enhance the frost resistance of concrete. Therefore, it has good use value and it is promising with a good prospect of application.
