摘要:

通过自密实混凝土在房屋建筑加固工程中的应用研究,对自密实混凝土在实际工程中原材料的选择、配合比的优化设计以及自密实混凝土的生产、施工及质量控制等问题进行了较详细的总结.工程应用结果表明:与其他加固方案相比,自密实混凝土在截面增大型钢筋混凝土加固工程中的应用可显著降低工程造价,且施工方便,因此其具有广阔的应用前景.

Abstract:

The mix ratio optimization of self-compacting concrete(SCC) and its construction technique such as the production, construction and quality control of SCC were studied in detail. The construction practices prove that the SCC enable the construction of strengthening engineering to be convenient, and the engineering quality to be improved. Compared with other kinds of strengthening methods, the construction cost of the techniques by using SCC can be decreased obviously and good benefit of technology and economy can be produced.
