본 발명은 철근콘크리트구조물 열화부의 단면보수 및 방수용 무기계 폴리머 모르타르 및 이의 제조방법에 관한 것이다.The present invention relates to an inorganic polymer mortar for cross-sectional repair and waterproofing of a reinforced concrete structure deterioration portion and a method for manufacturing the same.
일반적으로 철근콘크리트 구조물은 시공된 지 일정기간이 경과하면 구조물이 노화되어 콘크리트가 구조물에서 점차 박리 및 탈락이 이루어지는데 이를 보수 및 보강하여 구조물의 수명을 연장하기 위해서는 통상적으로 유기계 모르타르를 이용한 보수 및 보강공법을 적용한다.In general, reinforced concrete structures are aging after a certain period of construction, and the concrete gradually peels off and falls off from the structure. To repair and reinforce the structure, and to extend the life of the structure, repair and reinforcement using organic mortar is usually performed. Apply the method.
상기 유기계 모르타르는 3성분형(수지, 경화제, 골재)으로서 경화시간이 빠르고, 접착력이 우수하며, 압축강도와 굴곡 강도, 인장 강도가 우수한 장점이 있다.The organic mortar is a three-component type (resin, hardener, aggregate) has the advantage of fast curing time, excellent adhesion, excellent compressive strength, flexural strength, tensile strength.
반면에 이에 대한 단점도 있다.On the other hand, there are disadvantages to this.
즉, 상기 유기계 모르타르는 철근콘크리트구조물의 습윤 면에서는 사용이 불가능하며, 콘크리트 모체와의 탄성계수, 열팽창계수가 달라 발수성을 방해하여 단기간 내에 구조물로부터 박리 및 탈락이 발생할 수 있다.That is, the organic mortar is impossible to use in the wet side of the reinforced concrete structure, and the elastic modulus and thermal expansion coefficient with the concrete matrix may be different, thereby preventing water repellency and peeling and dropping from the structure in a short time.
또한, 상기 유기계 모르타르를 대량으로 타설시 콘크리트 모체에 영향을 미쳐 콘크리트 모체의 파괴로 인한 대량 타설이 불가능하며, 가사시간의 짧으므로 인한 작업성의 저하, 인체에 해로운 유해가스의 발생, 자외선에 의한 변색 등을 예로 들 수 있다.In addition, when placing the organic mortar in large quantities, it is impossible to mass-pour due to the destruction of the concrete matrix due to the impact on the concrete matrix. Due to the short pot life, deterioration of workability, generation of harmful gases harmful to the human body, and discoloration by ultraviolet rays Etc. can be mentioned.
이와 같은 문제점으로 인해 최근에는 상기 유기계 모르타르의 단점을 비교적 보완한 유, 무기계 혼합형 모르타르가 사용되고 있다.Due to such a problem, in recent years, organic and inorganic mixed mortars, which are relatively complementary to the disadvantages of the organic mortars, have been used.
상기한 유, 무기계 혼합형 모르타르는 2성분형으로서, 무기계 분말과 유기계 수지를 혼합한 형태로 제조된다.The oil-inorganic mixed mortar described above is a two-component type, and is prepared in the form of mixing an inorganic powder and an organic resin.
상기 유, 무기계 혼합형 모르타르는 콘크리트구조물의 습윤면에 시공이 가능하고, 높은 압축강도, 휨강도가 가능하며, 경화시간이 빨라 긴급 타설이 용이한 장점이 있다.The oil-inorganic mixed mortar can be installed on the wet surface of the concrete structure, high compressive strength, flexural strength is possible, fast curing time has the advantage of easy emergency pouring.
반면에 유, 무기계 혼용으로 콘크리트 모체와의 탄성계수, 열팽창계수가 달라 내구성이 떨어지며, 가사시간이 짧아 작업성이 떨어지고, 대 단면 복구에 따른 어려움이 있다.On the other hand, due to the mixed oil and inorganic system, the elasticity and thermal expansion coefficient of the concrete matrix are different, so durability is low, workability is low due to short pot life, and there is a difficulty in recovering large sections.
또한, 혼합수지가 pH 7 이하여서 철근부식의 우려가 있을 뿐만 아니라 인체에 해로운 포름알데히드 기체가 발생하여 밀폐된 공간에서는 질식의 우려가 있으며, 유기물의 자외선 노출로 인해 변형되어 콘크리트 모체로부터 박리 및 탈락이 발생되는 문제점이 있다.In addition, there is a risk of reinforcing corrosion as the mixed resin is less than pH 7, and formaldehyde gas, which is harmful to the human body, is generated, and there is a risk of asphyxiation in an enclosed space. There is a problem that occurs.
즉, 상기 유, 무기계 혼용 모르타르가 콘크리트 모체로부터 박리 및 탈락하는 이유는 콘크리트 모체와 수축 및 팽창, 탄성률이 상이함으로써 발생되며, 이는 현재 콘크리트구조물의 보수 및 보강에 필요한 적절한 조성물이 구비되지 않은 상태에서 이루어짐에 따라 철저한 보수 및 보강이 이루어지지 않고 있다.That is, the reason why the oil-inorganic mixed mortar is peeled and dropped from the concrete matrix is caused by a difference in shrinkage, expansion, and elastic modulus with the concrete matrix, which is not provided with a suitable composition for repairing and reinforcing the concrete structure. As a result, thorough repairs and reinforcements are not made.
다시 말해, 상기 유, 무기계 모르타르는 소량의 무기물을 첨가하여 무기계인 콘크리트구조물과 일부가 동일한 상태로 조성됨으로써 콘크리트 모체와의 견고한 부착력을 유지하도록 사용되나, 유기물적 특성이 강해 콘크리트와의 견고한 결합상태를 유지할 수가 없다.In other words, the oil and inorganic mortar is used to maintain a firm adhesion with the concrete matrix by adding a small amount of inorganic material in the same state as a part of the inorganic concrete structure, but with a strong organic properties, it is a strong bonding state with concrete Can't keep up.
뿐만 아니라 작업성 면에서도 2가지 (무기계 분말, 유기계 수지)를 혼용함에 따라 작업성이 떨어져 콘크리트구조물의 보수 및 보강이 제대로 이루어지지 않고 있는 실정이다. In addition, in terms of workability, due to the use of two kinds (non-mechanical powder, organic resin), the workability is poor, the situation of repair and reinforcement of the concrete structure is not properly made.
이에, 본 발명은 상기한 바와 같은 제문제점을 해결하기 위해 안출된 것으로서, 콘크리트와 동일한 성분인 무기계 모르타르를 이용하여 손상된 철근콘크리트구조물 부위에 보수 및 보강함에 따라 모르타르가 보다 견고하게 부착되어 높은 강도를 유지함과 동시에 내구성이 탁월한 철근콘크리트구조물 열화부의 단면보수 및 방수용 급결성을 갖는 무기계 폴리머 모르타르 및 이의 제조방법을 제공하는데 그 목적이 있다.Thus, the present invention was devised to solve the problems as described above, as the mortar is more firmly attached to the repair and reinforcement of the damaged reinforced concrete structure using inorganic mortar, which is the same component as concrete, to provide high strength. It is an object of the present invention to provide an inorganic polymer mortar having a cross section repair and waterproof fastness for maintaining a reinforced concrete structure having excellent durability while maintaining the same.

이하, 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail.
본 발명에 따른 철근콘크리트구조물 열화부의 단면보수 및 방수용 급결성을 갖는 무기계 폴리머 모르타르는 시멘트와, 물과, 세골재 및 혼화제로 구성되는 모르타르에 있어서, 상기 시멘트는 조강 포틀랜드 시멘트가 사용되며 100중량부에 대하여 물은 35∼60중량부, 세골재는 천연사, 규사, 인조골재 또는 이들이 혼합 사용되며 40∼150중량부, 혼화제는 10∼40중량부로 구성된다.Inorganic polymer mortar having cross-sectional repair and waterproofing fastness for the reinforced concrete structure deterioration portion according to the present invention, in the mortar composed of cement, water, fine aggregates and admixtures, the cement is used in the crude steel portland cement and 100 parts by weight Water is 35 to 60 parts by weight, fine aggregate is natural sand, silica sand, artificial aggregate or a mixture thereof is used 40 to 150 parts by weight, admixture is composed of 10 to 40 parts by weight.
또한, 상기 혼화제는 칼슘설파알루미나이트계 팽창재 1.5∼5.0중량부, 수축저감제 0.5∼4중량부, 유동화제 1.0∼4.0중량부, 증점제 4.0∼10.0중량부, 소포제 0.6∼1.0중량부, 재유화형 분말수지 2.0∼8.0중량부, 보강화이바 1.0∼1.7중량부, 구상 유동성 개선제 4.0∼10.0중량부로 구성된다.In addition, the admixture is 1.5 to 5.0 parts by weight of calcium sulfa aluminite-based expander, 0.5 to 4 parts by weight of shrinkage reducing agent, 1.0 to 4.0 parts by weight of fluidizing agent, 4.0 to 10.0 parts by weight of thickener, 0.6 to 1.0 parts by weight of antifoaming agent, reemulsifying type It consists of 2.0-8.0 weight part of powder resins, 1.0-1.7 weight part of reinforcement bars, and 4.0-10.0 weight part of spherical fluidity improving agents.
즉, 본 발명에 따른 철근콘크리트구조물 열화부의 단면보수 및 방수용 급결성을 갖는 무기계 폴리머 모르타르는 시멘트와, 물과, 세골재 및 혼화제로 구성됨을 특징으로 한다.That is, the inorganic polymer mortar having cross-sectional repair and waterproofing fastness of the reinforced concrete structure deterioration part according to the present invention is characterized by being composed of cement, water, fine aggregates and admixtures.
여기서, 상기 시멘트는 조강포틀랜드 시멘트로 분말도가 약간 곱고, 화학 성분상 석회분이 약간 많으며, 규산 3석회 함유량이 크다.Here, the cement is a crude steel portland cement slightly finer powder, slightly more lime in the chemical composition, the greater the content of tricalcium silicate.
일반적으로 조강 포틀랜드 시멘트는 습식법에 의해 만들어지며 보통 시멘트에 비해 장기강도는 크고, 응결은 약간 빠르나 대차는 없으며, 수화시의 발열은 약간 크다. 따라서, 분말도의 브레인 값은 5,000을 넘으므로 작업성을 얻기 위한 단위수량이 많이 요구되는데 모르타르의 압축강도 목표치를 58N/mmm2 이상으로 할 경우 물과 시멘트 중량비는 41% 이하로 한다.In general, crude steel Portland cement is produced by the wet method, and has a long-term strength, condensation is slightly faster but no balance, and heat generation is slightly larger than the normal cement. Therefore, since the brain value of the powder degree is more than 5,000, a large amount of units are required to obtain workability. When the target compressive strength of mortar is 58N / mmm 2 or more, the weight ratio of water and cement is 41% or less.

이것을 시멘트에 적당량을 혼합하여 수화하면 시멘트 바실러스를 다량 생성하며 팽창하여 그 후 건조수축을 보상한다. 그러나 혼합량이 지나치게 많으면 팽창균열을 일으키게 되므로 주의를 요한다.When hydrated by mixing an appropriate amount in cement, a large amount of cement bacillus is produced and expanded to compensate for dry shrinkage. However, if the mixing amount is too large, it will cause expansion cracks, so be careful.
또한, 상기 수축저감제는 플라이애쉬 45∼55 중량%, 무수석고 2∼5 중량%, 석회석 분말 15∼25 중량%, 고로슬래그 분말 10∼25 중량%로 구성된다.In addition, the shrinkage reducing agent is composed of 45 to 55% by weight of fly ash, 2 to 5% by weight of anhydrous gypsum, 15 to 25% by weight of limestone powder, and 10 to 25% by weight of blast furnace slag powder.

그리고, 상기 고로슬래그 분말은 철광석, 석회석, 코크스를 원료로 하여 적당한 비율로 조합, 고온에서 용해하여 환원하면 철은 비중이 크기 때문에 고로의 하층부에 가라앉고, 상층부에는 SiO2, Al2O3 등이 주성분인 암질이 CaO와 화합하여 용융상태로 부유한 것이다.In addition, the blast furnace slag powder is iron ore, limestone, coke as a raw material in combination at an appropriate ratio, and when melted and reduced at high temperature, iron is concentrated in the lower layer of the blast furnace due to the large specific gravity, the upper layer is a rocky material mainly SiO2, Al2O3, etc. It is combined with this CaO and is suspended in a molten state.
고로슬래그 분말의 비중은 2.85∼2.94 정도이며 평균은 2.90 정도이다.Blast furnace slag powder has a specific gravity of about 2.85 to 2.94 and an average of about 2.90.
고로슬래그의 형상은 매끈한 구곡상의 파면을 갖는 입방상으로 이를 입도 분석하면 최대입경은 48-150㎛, 평균입경은 10-16㎛, 10㎛ 이하의 양은 33-50%의 범위에 있으며, 44㎛ 잔분은 0.8-15.3% 정도이다.The shape of the blast furnace slag is a cubic shape with a smooth curved wave shape. When the particle size is analyzed, the maximum particle size is 48-150 μm, the average particle diameter is 10-16 μm, and the amount less than 10 μm is in the range of 33-50%, and 44 μm. The balance is about 0.8-15.3%.
본 발명에서 사용한 고로슬래그 분말은 CaO 성분을 함유하고 있으나, 수화열이 없고, 응결시간을 지연시켜 여름철에도 충분한 미장시간을 확보시켜주므로 초기 균열방지의 효과가 있다.The blast furnace slag powder used in the present invention contains a CaO component, but does not have a heat of hydration, thereby delaying the condensation time and ensuring sufficient plastering time in the summer, thereby preventing early cracking.
본 발명의 수축저감제에 있어서 10∼60% 사용되었으며 이 정도 범위내에서 가장 바람직한 수축저감 효과를 나타낸다.In the shrinkage reducing agent of the present invention, 10 to 60% is used, and within this range, the most preferred shrinkage reducing effect is obtained.
그리고, 상기 석회석 분말은 8∼20 중량%을 사용하는 것으로, 이는 고로 슬래그 분말의 작용을 조절하는 역할을 한다.And, the limestone powder is to use 8 to 20% by weight, which serves to control the action of the blast furnace slag powder.
순수한 석회석의 조성은 CaO 56%, CO2 44% 이지만 보통 고용체로서 MgCO, FeCO3, MnCO3 등을 함유하므로 MgO, FeO, MnO 등의 불순성분을 포함하고 있다.Pure limestone is composed of 56% CaO and 44% CO2, but usually contains solid impurities such as MgCO, FeCO 3 , MnCO 3 , and so on.
또한 점토나 갈철광과 같은 광분을 수반할 때가 많은데, 이때에는 SiO2, Al2O3, Fe2O3 등의 불순성분을 함유한다.In addition, it often involves light such as clay or iron ore, which contains impurities such as SiO 2 , Al 2 O 3 , and Fe 2 O 3 .
본 발명에서 석회석의 주성분은 CaCO3 함량이 약 80%(CaO 45%) 이상이면 사용이 가능하며, 8∼20 중량% 범위 내에서 사용시 가장 바람직하다.In the present invention, the main component of limestone can be used if the CaCO 3 content is about 80% (CaO 45%) or more, and is most preferable when used within the range of 8 to 20% by weight.

이는 점도의 향상으로 인한 유동성 증대 역할 뿐만 아니라 내구성 증진효과를 나타낸다.This not only increases the flowability due to the improvement of viscosity but also shows the effect of enhancing durability.
본 발명에서는 수용성 셀룰로오스 증점제인 하이드록시에틸셀룰로오스를 사용하였다.In this invention, hydroxyethyl cellulose which is a water-soluble cellulose thickener was used.
또한, 상기 소포제는 탄화수소 폴리글리콜계 등이 사용가능하며, 소포제의 사용량은 0.6∼1.0중량부로 하며, 0.6중량부 미만으로 사용하면 충분한 기포억제효과를 얻을 수 없고, 1.0중량부를 초과하여 사용하는 경우에는 경제적이지 못하다.In addition, the antifoaming agent can be used hydrocarbon polyglycol, etc., the amount of the antifoaming agent is 0.6 to 1.0 parts by weight, when used less than 0.6 parts by weight can not obtain a sufficient foam inhibitory effect, when used in excess of 1.0 parts by weight Not economical.
그리고, 상기 재유화형 분말수지는 제조된 건조 모르타르에 물을 부으면 재유화하여 수성 폴리머 디스퍼젼으로 행동한다.The re-emulsified powder resin is re-emulsified when water is poured into the prepared dry mortar to act as an aqueous polymer dispersion.
이렇게 재유화된 수지는 경화과정에서 형성하여 내수성을 증진시키고, 골재간의 접착성을 증진시키는 역할을 한다.This re-emulsified resin is formed during the curing process to improve the water resistance, serves to improve the adhesion between the aggregates.
