Preliminary study of effect of LiNO2 on expansion of mortas subjected to alkali-silica reaction
The effect of LiNO2 on the expansion of mortars made completely of reactive aggregate with five particle size fractions was investigated by means of an autoclave test. The results show that the effect of LiNO2 varies with its content and Na2O level, or more specifically, with the molar ratio of Li/Na in mortars. When the ratio reaches 0.8 at higher Na2O level (greater than 2 % in this study), ASR expansion is substantially suppressed and the ratio below or beyond this value will give different results. For the other cases of lower Na2O levels the results are distinguished from this and the best Li/Na molar ratios of 0.1, 0.3 and 0.5 corresponding to the Na2O levels of 0.5, 1.0 and 1.5 %, respectively, are recommended.
