预应力孔道压浆材料的配合比设计研究

Research on design of mixing ratio of prestressed duct grouting materials

从水灰比和压浆剂掺量出发,通过试验研究两者对孔道压浆材料性能的影响,从而明确了压浆料配合比设计的关键因素,为实际工程压浆料配合比的设计提供参考。

From the dosages of the water cement ratio and grouting agent,the paper undertakes the test and study on the influence of the two issues on the performance of the duct grouting materials,identifies the key factors for the mixing ratio design for the grouting materials,so as to provide the reference for the design of the mixing ratio of the grouting agent in factual projects.
