水泥水化时溶解的碱与活性骨料间化学反应的膨胀效应是一个十分复杂而又有重大实际意义的问题。本人掌握资料不足,到目前为止还没有达到全面认识这一问题的境地,不可能提出自己的总结性见解。这里只打算就唐明述、薛万荣同志所著“水泥与骨料中活性二氧化硅的膨胀反应”一文中所涉及的方法和推断,谈一谈个人的
The swelling effect of the chemical reaction between the dissolved alkali and the active aggregate during cement hydration is a very complex and significant practical problem. I have insufficient information, so far I have not reached a comprehensive understanding of this issue and I cannot propose my own summary opinions. Here I’d like to talk about the methods and inferences mentioned by Tang Mingshu and Comrade Xue Wanrong in the article “The swelling reaction of active silica in cement and aggregates”.
