Abstract

Among the numerous tests prescribed for assessing alkali-silica reactivity, ASTM C 1260 has become the preferred test method because of rapidity of the test procedure. However, a general concern about this method is the severity of the test conditions. The authors have evaluated the functionality of the method after modifying some of the important test parameters such as water-cement ratio, normality of test solution, length of test period, and curing. Combinations of high- and low-alkali cement with and without Classes C and F fly ash were included in the test program. The results are presented in this paper.
