新型水泥复合浆液的研制及其应用

Development and application of new kind of cement composite grout

从注浆材料方面解决注浆施工中出现的一些问题 ,通过大量试验 ,研制出了三种具有独特性能的新型水泥复合浆液 (CWP复合浆液 ) ,发现了一种新的高效缓凝剂———磷酸二氢铵 (NH4 H2 PO4 ) ,并对缓凝剂的作用机理进行了试验和分析 ,还介绍了早强型复合浆液在实际工程中的应用情况。

This paper tries to promote the performance of grouting material so as to resolve the problems of grouting emerged in construction. After many experiments this paper develops three types of cement composite grouts (CWP composite grouts) with unique performance, finds a new kind of retarder and discusses its mechanism on the basis of experiments. Furthermore ,the successful application of the early-hardening type of CWP composite grout is reported.
