Note (General): This paper describes effect of restraint of alkali silica reaction (ASR) by adding a small amount of chemical materials. In general, the measures for restraining the ASR are the total alkali content (under 3.0 kg/m3) and the use of mixed cement (blast-furnace slag cement type B or C, fly ash cement B or C). However, it is necessary to use more than a certain quantity (for example: 100 kg/m3). Therefore the development of the materials which can restrain ASR by adding a small amount is expected. In the experiments, mortars were made using ordinary portland cement, restraint materials and 4 types of reactive aggregates (2 types of chert, andesite, slate). Effects of restraint of 3 types of chemical materials were examined. They are the calcium propionate, the lithium-based compound and the aluminum-based compound. As a result, the expansions of mortars were restrained by the addition of the calcium propionate of 1.8 % in cement weight and also were restrained by the addition of the lithium carbonate of 2.5 % in cement weight.
