随着混凝土结构物的增加和施工新工艺的发展,对改善混凝土的性能,提高混凝土强度,达到减水增强,节约水泥提出了更高的要求,这也是我们建筑企业的重要任务之一。近些年来国内外对减水剂的使用研究都很重视,减水剂正以混凝土的五种成份显示其不可忽视作用。为此我们五公司三处于一九七八年开始,在混凝土工程中掺用开山屯木质素磺酸钙减水剂以来,收到了较好的效果,既能保证混凝土工程质量,又可节约水
With the increase of concrete structures and the development of new construction technologies, higher requirements have been raised for improving the performance of concrete, increasing the strength of concrete, achieving enhanced water reduction, and saving cement. This is one of the important tasks of our construction companies. In recent years, domestic and foreign researches on the use of water-reducing agents have attached great importance. Water-reducing agents are showing their non-negligible effects with the five components of concrete. For this reason, we started in 1978 in the fifth company and in the concrete project, we used Kaishantun lignin calcium sulphonate water reducing agent and received good results. It can not only ensure the quality of concrete works, but also save water.
