The Control of Hydration Heat by Using Liquefied Nitrogen in Mass Concrete Structures
초록
Temperature rise and restraint condition in mass concrete structures may induce the cracks at early ages. The method to prevent the cracks induced by heat of hydration has become the major concern in mass concrete structure. Therefore, the purpose of this study is to propose a method to control heat of hydration in mass concrete structures by using cryogenic liquefied nitrogen. The method in this study was applied to actual mass concrete structure to prevent the occurrence of thermal cracks at early ages. The surface observation of structure during more than one month shows that there are seldom cracks. This represent that the method in the study is effective in the control of heat of hydration.
