| Abstract: | Raw materials from the field engineering were used in this paper,and the concretes in different sections were designed according to various durability requirements such as deicer scaling,DF value,corrosion rate and depth of CI - diffusion.Results indicate that at the similar compressive strength and slump,the corrosion resistance and frost/deicer scaling resistance of concrete designed according to the durability are significantly higher than those of the common-used concrete designed by the traditional standard.Furthermore,the application of concrete with high durability in the bridge was discussed. |
| Keywords: | Corrosion resistance Deicer-scaling resistance Frost resistance Air-entraining agent |
