摘要
全面比较了水工混凝土与普通混凝土的差异,系统地分析了这些差异在碱骨料反应方面所导致的不同行为。在此基础上发现当碱骨料反应发生时,水工混凝土比普通混凝土有更大的危险性。同时也对在普通混凝土基础上得出的一些评判方法及判据、混凝土安全碱含量等控制指标能否用于水工混凝土提出疑问。
In this paper,the authors compared the concrete for hydraulic projects with the ordinary concrete in terms of alkaliaggregate reaction.The different behavior in alkaliaggregate reaction induced by the difference between the two kinds of concrete was analyzed.It was found that the concrete for the hydraulic projects was more dangerous than the ordinary concrete when alkaliaggregate reaction occurred.Some questions were raised on the evaluating methods and criteria,which had been derived on the basis of ordinary concrete and to be used to the used to the concrete for hydraulic projects.
