摘要
分析了化学外加剂对混凝土抗冻融性能、抗渗性能、碱集料反应、碳化及钢筋锈蚀等方面的影响。提出了合理地利用化学外加剂 ,发挥其积极功能 ,克服其存在之不足 。
It is a discussion on the effect of the chemical Admixtures on some properties of the concrete, such as its frost-resistence, anti-solving, anti-permeability, alkali-aggregate reaction, anti-carbonate and anti-rust of the reinforcing-bar in it. Meanwhile, such questrons are discussed in the paper as how to make reasonable use of the chemical admixtures, how to give play to its positive function, how to overcome the weakness and then enhance the durability of conerete at the most. Furthermore, some effective measures are offtered here.
