The alkali-aggregate reaction and blast-furnace slag effect in high-strength concrete were studied in this paper. From the results of this study, it is possible to draw the following conclusions : (1) In high-strength concrete, because of high alkali content, the possibility of alkali-aggregate reaction is much higher than (2) The occurrence of large expansion can be prevented by usi ng non-reactive aggregate, which has been judged according to the mortar bar and chemical method as specified in JIS A 5308, in high-strength concrete. (3) The replacement of cement by 30% of blast-furnace slag and the utilization of low alkali cement can prevent (4) the alkali-aggregate reaction from causing large expansion in high-strength concrete.
