CONCRETE FORMULATING COMPOSITION HAVING IMPROVED FREEZE-THAW RESISTANCE
The present invention relates to a concrete mixing composition having improved strength and freeze-thaw resistance. The concrete mixing composition includes sodium chloride, ammonium chloride, calcium chloride, magnesium chloride, soda ash, a surfactant, propylene glycol, nitrous acid, calcium nitrate, and a fluidizing agent, so that the strength of concrete is increased, and cracks and sectional defects of concrete caused by a frost damage at a sub-zero temperature are prevented.
본 발명은 강도 및 내동해성이 향상된 콘크리트 배합 조성물에 관한 것으로, 상기 콘크리트 배합 조성물은 염화나트륨, 염화암모늄, 염화칼슘, 염화마그네슘, 소다회, 계면활성제, 프로필렌 글리콜, 아질산, 질산칼슘, 및 유동화제를 포함하여, 콘크리트의 강도를 증진시키고, 영하의 온도에서 동해에 의한 콘크리트의 균열 및 단면 결함을 방지할 수 있다.
