| Abstract: | The shrinkage-compensating concrete is adopted in Chongqing Jiangjin Guanyinyan Yangtze River Bridge wet cast-in-place bridge expansion joints.Aiming at different types and mixing amount of expanders,the orthogonal tests on strength and restrictions on expansion are carried out.Consequently,the type of expanders,the mixing amount and the mix ratio of expansive concrete suitable for this bridge are selected out. |

| Keywords: | shrinkage-compensating concrete restrictions on expansion mix ratio |
