Ultra Rapid Hardening Concrete Composition and Road Concrete Repairing Method Using The Same
The present invention provides an ultra-fast hardening concrete composition and a concrete road repairing method using the same. The ultra-fast hardening concrete composition includes 10 to 20 wt% of ultra-fast hardening cement, 0.5 to 1.0 wt% of activated silica, 1.0 to 5.0 wt% of liquid latex (40 to 50 % of solid content), 40 to 50 wt% of sand, and 30 to 40 wt% of aggregate, and 5 to 10 wt% of water. The composition ratio of active silica to liquid latex is 1 : 2.4 to 1 : 3.0 in a weight ratio.
본 발명은 초속경 시멘트 10~20 중량%, 활성실리카 0.5~1.0 중량%, 액상 라텍스 1.0~5.0 중량%(고형분 기준 40~50%), 모래 40~50 중량%, 골재 30~40 중량%, 및 물 5~10 중량%를 포함하되, 활성실리카와 액상 라텍스의 조성비가 중량비로 1:2.4~1:3.0인 것을 특징으로 하는 초속경 콘크리트 조성물 및 이를 이용한 이를 이용한 콘크리트 도로 보수방법을 제공한다.
