摘要
本文着重介绍碱-集料反应发生机理、研究现状及预防AAR途径。鉴于我国年混凝土生产量超过20亿立方米,碱活性集料分布广泛,解决碱-集料反应问题迫在眉睫;预防AAR途径可采取近期可实施措施和长期论证可采取的措施相结合的方法。
This paper indicates mechanism of alkali-aggregate reaction,actuality of its research and the way in preventing AAR. In China annual output of concrete in excess of 2000,000,000 m3 and alkali-reactive aggregate widely distributed, it is imperative for us to solve the problem of AAR. Effective way of inhibiting AAR. will associate short-term practicable plans with long-term demonstrative plans.Keywords： alkali-aggregate reaction; mechanism;preventive ness; effective way.
