Chemical grouting materials contain a lot of specieses , each there is characteristics . according to to the investigation result of the current chemical grouting material , make sure the way to research and be applied of modified chemical grouting material 化灌材料种类繁多,各有特点,根据对现有化灌材料的调研比选,确定了环氧化学灌浆材料的改性研究及应用的方向。
However , its cement rock has disadvantages - low strength , drying shrinkage and low durability . to apply the gin grouting method in practice and improve the grouting quality and its durability , it is necessary to develop the high performance grouting material ,为了gin灌浆法的推广应用和技术提高,切实保证高坝工程中的灌浆质量和可靠耐久性,迫切需要研制出一种高性能稳定性灌浆材料。
The superfine cement is a new kind of inorganic material for grouting . because the grain size is very fine , they can go into the thin cracks , making the fissured foundation form a mass without cracks to prevent seepage . the method is efficient in seepage preventing and worth extending 超细水泥是新一代的无机灌浆材料,颗粒细小,可以灌入普通水泥难以灌入的极细微的裂隙,很好地解决坝基的防渗问题,是一种行之有效和值得推广的坝基防渗材料。

Enlarging concrete section , enveloping iron and strengthening with carbon fiber sheet are the widely - used methods to strengthen concrete column under axial compression , although these methods have their respective defects : wet - work in construction sit , long time for curing and deformation of appearance , the aging of pouring compounds and so on 目前对轴心受压混凝土构件而言,常用的加固方法有混凝土加大截面法、外包钢加固法、碳纤维布加固法等。而这些方法各有其缺陷,如现场湿作业问题、养护及外观问题、灌浆材料或粘接剂的老化问题等。
The products are the raw material of polyurethane elastomer , coating and adhesives , which react with isocyanate to give a chemical grouting material that has been widely used for seepage - proofing and blocking up the loophole of tunnel , dam , underground projects and mine - pits , as well as foundation reinforcement 本类产品为聚氨酯弹性体、涂料、粘结剂的原料,与异氰酸酯反应制得的化学灌浆材料,广泛用于隧道、水坝、地下工程、矿坑层面的防水堵漏及建筑物的地基加固。
