HIGH DURABILITY CONCRETE COMPOSITION WITH EXCELLENT FLUIDITY AND LONG-TERM DURABILITY
Disclosed is a high-durability concrete composition enhanced in fluidity and long-term durability applicable to reinforced concrete structures, including bridge decks, which are required to have durability performance by being exposed to corrosion conditions of reinforcing steel or deterioration of concrete, and structural repairing and reinforcing materials. The high-durability concrete composition enhanced in fluidity and long-term durability according to the present invention comprises: 15-25 wt% of cement; 30-40 wt% of fine aggregate; 35-45 wt% of coarse aggregate; 4-10 wt% of water; 1-6 wt% of a polymer admixture. The polymer admixture includes an SB polymer emulsion, a polycarboxylic acid compound; a preserver, and an anionic surfactant.
철근 부식 또는 콘크리트 열화 환경에 노출되어 내구성능 확보가 요구되는 교량 바닥판을 비롯한 철근 콘크리트 구조물, 구조물 보수 및 보강재로 활용 가능한 유동성 및 장기 내구성을 향상시킨 고내구성 콘크리트 조성물에 대하여 개시한다. 본 발명에 따른 유동성 및 장기 내구성을 향상시킨 고내구성 콘크리트 조성물은 시멘트 15 ~ 25 중량%, 잔 골재 30 ~ 40 중량%, 굵은 골재 35 ~ 45 중량%, 물 4 ~ 10 중량% 및 폴리머 혼화제 1 ~ 6 중량%를 포함하며, 상기 폴리머 혼화제는 SB 폴리머 에멀젼, 폴리카르본산계 화합물, 유지제 및 음이온성 계면활성제를 포함하는 것을 특징으로 한다.
