水泥及混凝土中的有害碱与无害碱

Deleterious Alkali and Non-deleterious Alkali in Cement and Concrete

论述了混凝土和水泥及其它组成成分中碱的存在形式 ,及不同形式的碱与碱 -集料反应之间的关系。提出了“有害碱”的概念。并建议用“有害碱”来评价水泥及混凝土中的碱对碱 -集料反应的影响。

? The forms of alkalis in concrete,cement and other ingredients have been analyzed,and the effect of the forms of alkalis on the alkali aggregate reaction(AAR)is also discussed.The concept of deleterious alkali is proposed,and it is suggested that the effect of the alkalis in cement and concrete on AAR should be evaluated by deleterious alkali. 〔
