The purpose of this study is to investigate a hydration heat property of mortar using endothermic reaction of xylitol and phase change materials(PCM). For this reason, this study is to control the hydration heat by replacing mineral admixture or adding xylitol and Sodium sulfate dodecahydrate, calcium nitrate tetrahydrate, sodium phosphate dibasic dodecahydrate as PCM. Mortar to produce 0.2% or 0.3% of the amount of xylitol, sodium sulfate dodecahydrate, calcium nitrate tetrahydrate, sodium phosphate dibasic dodecahydrate, respectively, 2% of the full amount of cement were made. Also, plain mortar and mortar containing blast-furnace slag (30%) were made, in order to compare with mortar using PCM and xylitol. A gillmore needle, measurement of hydration heat, compressive strength and tensile strength were tested. From the test results, a initial setting of mortar containing 0.2% xylitol and 2% sodium phosphate dibasic dodecahydrate was found to become fast. And a initial setting of mortar containing 0.3% xylitol was found to become slow. Also, mortar containing xylitol and PCM can reduce of maximum temperature and increase compressive and tensile strength compared to the plain mortar and mortar containing blast-furnace slag. |
