| Abstract: | HL-HGM high strength non-shrinkage grouting material is a kind of grouting material characterized as high strength, non-shrinkage and high fluidity. In this paper, researches on the influence of different water /material ratio on the performances of fluidity, water-draining ratio, hardening time and strength etc. of grouting material have been done, meanwhile, the application practice of this material to the installment of 50m simply supported box girders of of Hangzhou Bay Sea-Crossing Bridge. Compared to epoxy resin mortar grout, adopting this grouting material can simplify the construction technics, short construction schedule, improve the quality of project, saving cost and be more environmental. |
