REPAIR COMPOSITION CONTAINING BASALT POWDERS FOR CONCRETE STRUCTURE AND REPAIRING METHOD FOR CONCRETE STRUCTURE USING THE SAME
The present invention relates to a repair material composition of a concrete structure, containing cement and aggregate. After basalt ore is melted and cooled based on 100 parts by weight of solid content, the composition further comprises: 0.01 to 0.3 part by weight of powdered basalt powder and 0.1 to 0.2 part by weight of a compound represented by chemical formula 1 and a compound represented by chemical formula 2, respectively. When the repair material composition including the compounds are applied for repair on a concrete structure to be repaired, the basalt powder prevents neutralization of concrete and improves flexural strength thereof. Accordingly, the compounds with strong chemical structure are hardened by ultraviolet rays especially on a surface of a layer to be repaired to form a repaired layer with increased compressive strength.
본 발명은 시멘트 및 골재를 포함하는 콘크리트 구조물의 보수재 조성물로서, 고형분 100 중량부를 기준으로 현무암 원석을 용융 및 냉각시킨 후 분말화한 현무암 분말 0.01 내지 0.3 중량부와 화학식 1로 표시되는 화합물 및 화학식 2로 표시되는 화합물을 각각 0.1 내지 0.2 중량부를 더 포함하는 것을 특징으로 한다. 이들 화합물들을 포함하는 보수재 조성물을 보수 대상인 콘크리트 구조물에 타설하여 보수시, 현무암 분말에 의해 콘크리트의 중성화 방지 및 휨 강도가 향상되며 강직한 화학구조를 가진 화합물들이 특히 보수층 표면에서 자외선에 의해 경화되어 압축 강도가 증대된 보수층을 형성한다.
