The 27 aggregate samples were collected from the stockpile of selected 8 ready-mixed concrete plants over the main river area in this district. The mineralogical features of the river sand and gravel, and their alkali-silica reactivity were tested by both the chemical method and the mortar bar method according to the specification by JIS A 1145-2001 and JIS A 1146-2001. Furthermore, a lot of cores were drilled from the concrete specimens, which were subjected to the accelerated curing condition of the immersion into 1N NaOH solution at 80℃ or the saturated NaCl solution at 50℃ in order to evaluate the alkali-silica reactivity of the concrete itself. By measuring the expansion behaviors of the cores in the accelerated curing condition, the rapid test method for the evaluation of the alkali-silica reactivity of the concrete itself was developed., 金沢大学理工研究域環境デザイン学系}, pages = {1075--1080}, title = {北陸地方の河川産骨材を使用したコンクリートのアルカリシリカ反応性の評価法の開発(<特集>コンクリート用骨材および混和材料)}, volume = {536}, year = {2004} }
