The result of concrete seepage test shows that the way mixing steel fiber and expansion agent with concrete to strengthen the anti-crack and anti-seepage performance of the concrete materials is effective. The waterproof mechanism of expansive concrete with steel fiber is analyzed. The result of this research is applied to the practical rigid waterproof projects and has brought about a satisfactory effect.
Keywords:  expansive concrete; steel fiber; concrete seepage test; rigid waterproof
