当前我国正处于一个高速城市化阶段,城市化人口不断增加,同时城市建成区面积也在不断扩大。城市的人口越来越稠密,所以已经有越来越多的高层建筑投入了建设和使用。高层建筑往往具有比较厚的承台,需要大量的水泥混凝土,所以我们称之为大体积砼工程。在大体积砼施工过程中,往往都会比较大量地使用外加剂,所以本文对此进行说明,首先探讨了外加剂的类型以及其自身具有的特点,然后以此为基础,讨论了外加剂的使用情况以及相关注意事项,希望可以给相关工作人员提供一些参考。
At present, our country is in a stage of rapid urbanization, the population of urbanization is increasing, and the area of urban built-up areas is also expanding. As cities become more densely populated, more and more high-rise buildings have already been put into construction and use. High-rise buildings often have a relatively thick cap, requires a lot of cement concrete, so we call the mass concrete works. In the mass concrete construction process, tend to be more extensive use of admixture, so this article to illustrate, first of all, to explore the type of admixture and its own characteristics, and then as a basis, discussed the use of admixture The situation and the related matters needing attention, hope can provide some reference for relevant staff.
