The present invention relates to a hydration heat reducer composed of a hydration heat reducing aid and a curing accelerator, the hydration heat reducing aid containing strontium hydroxide octahydrate (Sr(OH)2·8H2O), silicon oxide (SiO2), calcium hydroxide (Ca(OH)2), and aluminum oxide (Al2O3), wherein the hydration heat reducer, compared with a conventional hydration heat reducer, provides higher initial strength and less initial deformation during concrete construction, leading to improved workability. La présente invention concerne un réducteur de chaleur d'hydratation composé d'un auxiliaire de réduction de chaleur d'hydratation et d'un accélérateur de durcissement, l'auxiliaire de réduction de chaleur d'hydratation contenant de l'hydroxyde de strontium octahydraté (Sr(OH)2·8H2O), de l'oxyde de silicium (SiO2), de l'hydroxyde de calcium (Ca(OH)2), et de l'oxyde aluminium (Al2O3), le réducteur de chaleur d'hydratation, comparé à un réducteur de chaleur d'hydratation classique, fournit une résistance initiale plus élevée et une déformation initiale moindre durant la construction du béton, conduisant à une aptitude améliorée au façonnage. 본 발명은 수산화스트론튬 8수화물(Sr(OH)2·8H2O), 산화규소(SiO2), 수산화칼슘(Ca(OH)2), 산화알루미늄(Al2O3)를 포함하는 수화열 저감조제 및 경화촉진제로 이루어진 수화열 저감재에 관한 것으로, 종래의 수화열 저감재에 비하여 콘크리트 시공 시 초기강도가 높으며 초기변형이 적어 작업성이 향상된 수화열 저감재에 관한 것이다.
