大掺量磨细矿渣双掺混凝土在南水北调天津干线TJ4-4标中的应用

Application of Double Mixed Concrete with Much Grading Fine Slag in Tianjin Route TJ4-4 Package of South to North Water Diversion Project

文中介绍了南水北调天津干线箱涵混凝土双掺配合比研究情况,说明了大掺量磨细矿渣双掺混凝土既能达到南水北调天津干线对混凝土"抑制碱骨料反应"和"抗地下水化学侵蚀"的要求,提高了混凝土的质量要求,还利用了工业废料,减少了环境污染,节约了能源,还降低了混凝土的造价。这是一项可持续发展的先进技术,值得大力推广。

The paper makes an introduction to the research on the ratio for double mixed concrete in Tianjin route box culvert for south to north water diversion project.The result shows that double mixed concrete with much grading fine slag meets the requirements of ＂controlling alkali aggregate reaction＂ and ＂resisting groundwater chemical corrosion ＂.It not only improves the concrete quality,but also takes full advantage of waste materials,reduces the environmental pollution,saves energy and cuts down the concrete cost,which is a sustainable advanced technology and worthy popularizing.
