摘要
80年代中,随着混凝土技术的发展,单方水泥用量增多,且华北、西北地区生产的水泥含碱量偏高,又使用含碱外加剂。在这种情况下,混凝土工程中碱-骨料反应病害增多。要预防碱-骨料反应对混凝土工程的损害,最好的方法就是使配制的混凝土中不含碱-骨料反应因素。
Over the years of 1980's,the concrete's production technology has been developed widely in China,and the consumption of cement has been increased accordingly.In the north China and north-west China regions,the consumption of high alkali cement and alkali admixture has been on the rise in larger amount.Under these conditions,therefore,concrete's trouble and damage due to reactions of alkali-aggregate has been on the rise considerably.In order to prevent these concrete's trouble and damage due to reactions of alkali-aggregate,the best method is to produce a kind of non-reaction of preferably a reaction-proof alkali-aggregate.
