Description

해조류를 이용한 친환경 방수용 콘크리트 조성물 및 이를 이용한 시공방법{Eco-Friendly Concrete Composition for Waterproof and Constructing Methods Using Thereof}Eco-Friendly Concrete Composition for Waterproof and Constructing Methods Using Thereof}

본 발명은 방수용 콘크리트 조성물에 관한 것으로서, 보다 상세하게는 건축물의 옥상, 수처리 시설 구조물, 지하구조물, 터널, 교량 슬래브, 옥상녹화용 바닥면 등의 방수시공에 사용되는 방수용 콘크리트 조성물, 특정적으로 해조류를 이용한 친환경 방수용 콘크리트 조성물 및 이를 이용한 시공방법에 관한 것이다.
The present invention relates to a waterproof concrete composition, and more specifically, a waterproof concrete composition used for waterproof construction, such as a roof of a building, a water treatment facility structure, an underground structure, a tunnel, a bridge slab, a rooftop greening floor, and specifically a seaweed It relates to an eco-friendly waterproof concrete composition and a construction method using the same.

건축물과 토목구조물에 주로 사용하는 콘크리트의 내구성을 향상시키기 위한 목적으로, 콘크리트 구조물이 함유하고 있는 수분을 배출하고 통기가 가능한 절연(또는 부분 절연)된 방수층을 시공하기 위해서 일반적으로 현장에서 대상 콘크리트 구조물에 직접 방수층을 시공하는 방법이 사용되고 있다.In order to improve the durability of concrete mainly used in buildings and civil structures, concrete structures are generally used on-site in order to construct an insulated (or partially insulated) waterproof layer that can drain moisture contained in concrete structures and allow ventilation. The method of constructing a waterproof layer directly to the is used.

즉, 종래에는 현장에서 방수층을 콘크리트 구조물에 직접 설치하고, 방수층 위에 수지를 도포한 후 경화시켜 연질, 또는 경질의 방수층을 시공하는 방법이 사용되어 왔다. That is, in the related art, a method of installing a soft or hard waterproof layer has been used in the field by directly installing a waterproof layer on a concrete structure, applying a resin on the waterproof layer, and curing the resin.

그러나 종래의 방법에 의하면 현장에서 방수층 시공의 모든 단계가 처리되어야 하므로, 방수층을 설치하는 현장조건에 따라 작업시간이 지연됨과 동시에 작업능률이 저하되는 문제점이 있었다.However, according to the conventional method, all the steps of the waterproofing layer construction must be processed in the field, and there is a problem that the work time is delayed and the work efficiency is lowered according to the site conditions for installing the waterproofing layer.

특히, 건물이나 구조물의 누수 되는 부분으로 슬라브, 벽체, 지하실 등을 대표적으로 들 수 있으며, 옥상 슬라브의 방수층이 노후되어 새로운 방수층 등을 시공하여 개수공사를 하는 경우, 누름 건축물 방수층에 도달하는 약액 주입관을 세우고 전기 약액주입관을 통해서 이소시아네이트 또는 이소시아네이트를 주성분으로 하는 가수반응약액을 주입하여 적어도 건축물 옥상을 형성하는 천정, 콘크리트 및 방수층 균열층 중에 있어서, 상기 주입의 남은 물과 상기 가수분해 약액과의 반응에 따라 겔 물질과 탄산가스를 상기 균열중에 생성시켜 탄산가스 기포를 내장하는 다포(多包)구조 겔 물질을 상기 균열속에 접착보강 충전하여 방수층을 형성하며 방수하는 방법, 콘크리트 구조물의 누수부분을 지수처리하기 위한 누수보수장치에 있어서 누수부분 및 누수간극의 개구부 테두리에 접하는 부분에 형성된 들어간 홈에 수팽창성 지수제가 삽입되어 충진되는 동시에, 이 지수제는 들어간 홈의 개구부에 고설된 백업재에 의해 백업되는 방법 등이 일본국 특허 소 57-104767호, 동소 57-10476호, 일본국 실용신안공개 소 59-47750호 등에 개시되어 있다.Particularly, the leaked part of a building or structure may be a slab, a wall, a basement, and the like.In the case of renovation by constructing a new waterproof layer due to the deterioration of the waterproof layer of the rooftop slab, the injection of chemicals reaching the waterproof layer of the pressed building In a ceiling, concrete, and waterproof layer crack layer which forms at least a building roof by injecting a isocyanate or isocyanate-based hydrolysis chemical solution through an electric chemical injection tube, the remaining water of the injection and the hydrolysis chemical liquid According to the reaction, a gel material and carbonic acid gas are formed in the cracks, and a multi-porous gel material containing carbon dioxide gas bubbles is reinforced by filling and strengthening in the cracks to form a waterproof layer. Leakage part and part in water leak repair device for water treatment The water-expandable index agent is inserted and filled into the recessed groove formed in the portion which is in contact with the opening edge of the leak gap, and the method is backed up by the backup material laid in the opening of the recessed groove. No. 57-10476, Japanese Utility Model Publication No. 59-47750, and the like.

그러나 이러한 방법은 균열층에는 효과가 있으나, 콘크리트의 기공율이 45%이상 함유하는 옥상이나 벽체에는 전혀 사용할 수 없고, 또한 콘크리트 철근구조물에서 콘크리트 내부의 철근이 콘크리트와 분리되거나 간극이 형성된 경우에는 전혀 사용할 수 없는 문제점이 있다.However, this method is effective for cracking layers, but it cannot be used at all on the roof or walls containing 45% or more of porosity of concrete, and also when the reinforcing bars in concrete are separated from concrete or gaps are formed. There is no problem.

본 발명은 상기와 같은 문제점을 해결하기 위해 창출한 것으로서, 콘크리트 조성물 자체에 방수성능을 부가한 방수성 콘크리트 조성물, 특정적으로 해조류를 이용한 방수성 콘크리트 조성물을 제공하고자 한다.The present invention has been made to solve the above problems, and to provide a waterproof concrete composition, specifically a waterproof concrete composition using seaweed in addition to the waterproof performance to the concrete composition itself.

또한, 본 발명은 방수 성능뿐만 아니라 콘크리트 조성물이 요구하는 내구성, 압축강도 등이 향상된 방수성 콘크리트 조성물을 제공하고자 한다.
In addition, the present invention is to provide a waterproof concrete composition with improved waterproof performance, durability, compression strength, etc. required by the concrete composition.
