REPAIR COMPOSITION FOR CONCRETE STRUCTURE AND REPAIRING METHOD FOR CONCRETE STRUCTURE USING THE SAME
The present invention relates to a repair material composition for concrete structures including cement and aggregates. Based on 100 parts by weight of solid content, the repair material composition comprises 0.01 to 0.3 parts by weight of basalt powder obtained by melting and cooling basalt ore and pulverizing the same, 0.1 to 0.5 parts by weight of tartaric acid, and 0.1 to 0.2 parts by weight of each of a compound represented by chemical formula 1, a compound represented by chemical formula 2, and a compound represented by chemical formula 3. When repair is performed after a repair material composition containing these compounds is poured into a concrete structure to be repaired, the neutralization of the concrete is prevented and the bending strength is improved by the basalt powder. According to the present invention, compounds with a rigid chemical structure are hardened by ultraviolet rays especially on the surface of a water retention layer, and thus it is possible to form a water retention 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 중량부, 타르타닉산 0.1 내지 0.5 중량부, 화학식 1로 표시되는 화합물, 화학식 2로 표시되는 화합물 및 화학식 3으로 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.
