Concrete composition and construction method for repair of transportation facilities
The present invention comprises: an adhesive applied after removing foreign substances from a concrete structure that is an object to be repaired; an elastic separator applied to the repair object to which the adhesive is applied and applied by mixing a curing agent and an acrylic emulsion; an ultra-fast-hardening polymer concrete applied to the repair object to which the elastic separator is applied and including an ultra-fast-hardening mortar made of a fast-hardening cement-based mixture, micro-hydrophilic fibers with a length of 8 mm, an inorganic expandable material, a siloxane-based waterproofing agent, a thixotropic agent, a water reducing agent, a reaction accelerator, a retarder, and silica sand, coarse aggregate, a liquid composition consisting of an SB Latex emulsion resin, an amine admixture, a defoaming agent, a wetting agent, and water, and water. Accordingly, the present invention can prevent structural damage.
본 발명은, 보수대상물인 콘크리트 구조물로부터 이물질을 제거한 후에 도포되는 접착제; 상기 접착제가 도포된 보수대상물에 도포되고, 경화제와 아크릴 에멀젼을 혼합하여 도포되는 탄성분리막; 상기 탄성분리막이 도포된 보수대상물에 도포되고, 속경성 시멘트계 혼합물, 길이 8mm 마이크로 친수성 섬유, 무기팽창재, 실록산계 방수제, 칙소제, 감수제, 반응촉진제, 지연제, 규사로 이루어진 초속경 모르타르와, 굵은골재와, SB Latex 에멀젼수지와, 아민계 혼화제, 소포제, 습윤제, 물로 이루어지는 액상조성물과, 물을 포함하는 초속경 폴리머 콘크리트를 포함하는 것을 특징으로 한다.
