最近,天津水泥厂开发的硅酸盐系列低碱水泥通过鉴定,专家认为,此项低碱水泥的技术成果达到了国际先进水平。据介绍,目前国内市场上的水泥碱含量大都较高,造成混凝土碱骨料反应,直接影响了混凝土建筑物的耐久性。1996年9月中国工程院在北京召开了“京津地区碱骨料反应”报告座谈会,与会专家和工程技术人员认为,混凝土碱骨料反应是京津地区混凝土发生严重失效和破坏的主要原因之一。为解决这一问题,1997年天津水泥厂将生产硅酸盐低碱水泥列入攻关计划,经过艰苦努力,摸索出以砂岩替代粘土的配料方案,同时也解决了生产工艺上的问题。目前已成功地生产出
Recently, the silicate series of low-alkali cement developed by the Tianjin Cement Plant passed the appraisal. Experts believe that the technical achievements of the low-alkali cement have reached the international advanced level. According to reports, the cement alkali content on the domestic market is currently high, causing concrete alkali aggregate reaction, which directly affects the durability of concrete buildings. In September 1996, the Chinese Academy of Engineering held a symposium on the report of “Alkaline Aggregate Reaction in the Beijing-Tianjin Area” in Beijing. Participating experts and engineering and technical personnel considered that concrete alkali-aggregate reaction is the main cause of serious failure and destruction of concrete in the Beijing-Tianjin region. one of the reasons. In order to solve this problem, in 1997, Tianjin Cement Plant listed the production of low-alkali silicate cement as a key project. After arduous efforts, it explored a plan to replace the clay with sandstone, and also solved the problems in the production process. Has been successfully produced
