Description
본 발명은 다기능성 인조골재를 이용한 수중콘크리트 구조물 보수보강재에 관한 것으로, 더욱 상세하게는 다기능성 인조골재를 일정비율 혼합 보수보강재를 제조하여, 에폭시 수지의 점도를 낮추어 유동성을 우수하게 하고, 가격을 대폭 인하시키는 다기능성 인조골재를 이용한 수중콘크리트 구조물 보수보강재에 관한 것이다.The present invention relates to a water-reinforced concrete structure reinforcement using multi-functional artificial aggregate, and more specifically, to produce a multi-rate artificial aggregate fixed ratio reinforcement, to improve the fluidity by lowering the viscosity of the epoxy resin, the price The present invention relates to a water reinforcement for underwater concrete structures using multi-functional artificial aggregates that drastically reduce.
일반적으로, 철근콘크리트의 토목, 건축 구조물에 콘크리트가 박리, 박락, 비정상적인 크랙 등 여러가지의 열화현상으로 콘크리트의 압축강도와 철근의 인장강도가 저하되어 철근콘크리트의 손상 및 붕괴현상과 구조물의 부식과 파손등으로 인한 안전사고에 대한 관심이 높아지면서, 구조물 보수/보강에 관련된 산업제품 수요가 창출되고, 이로 인한 시장수요도 점차 확대되고 있으며, 구조물 보수/보강에 관련된 업종 종사자와 이와 관련있는 산업분야가 급증하고 있는 추세이다.In general, due to various deterioration phenomena such as peeling, peeling, abnormal cracks, etc. of reinforced concrete civil engineering and building structures, the compressive strength of concrete and tensile strength of reinforcing steel are reduced, resulting in damage and collapse of reinforced concrete and corrosion and breakage of structures. As interest in safety accidents is increasing, the demand for industrial products related to the repair and reinforcement of structures is created, and the market demand is gradually increasing due to this. The trend is soaring.
종전의 각종 토목 및 건축을 포함하여 모르타르 콘크리트의 시설구조물, 철 물구조물, 금속구조물을 보수, 보강하는 조성물들은 구조물의 표면에 도장하는 피막성을 갖는 도장제이거나, 모르타르에 첨가하는 첨가제 및 구조물을 마감처리하는 마감제로써, 시멘트콘크리트의 시설구조물에서는 표면에 형성되는 피막으로 하여금 대기중의 탄산가스의 침투를 지연시키어 고알카리성인 시멘트의 중화속도를 느리게 함으로써, 시멘트콘크리트의 시설구조물의 강도유지와 철근의 부식도 방지하여 시멘트콘크리트의 시설구조물의 수명을 연장하며 또한, 철근구조물 및 금속구조물에서도 표면에 형성되는 피막에 의해 내부식성을 부여하여 손상을 예방하는 것으로 알려져 있다.Compositions for repairing and reinforcing the structures, iron structures, and metal structures of mortar concrete, including various types of civil engineering and construction, are coating agents having a coating property on the surface of the structure, or additives and structures added to the mortar. As a finishing agent for the finishing of cement concrete, the surface structure of cement concrete delays the penetration of carbon dioxide gas into the air, thereby slowing down the neutralization rate of highly alkaline cements, thereby maintaining the strength and reinforcing of the structural structure of cement concrete. It is also known to prevent corrosion by extending the service life of facility structures of cement concrete, and to prevent damage by providing corrosion resistance by coatings formed on the surface of reinforced structures and metal structures.
그러나, 일반적인 보수보강재의 경우 화산암의 자갈 및 모래가 사용되어 콘크리트에 열화현상이 가속되는 경우에 중화를 지연시키는 효과가 우수하다고 알려져 있으나, 이들의 조성물은 가격이 고가이고 보수보강 대상구조물의 열화상태에 따라 적정제품을 선정하고 이들 제품을 순서적으로 시공하여야 하는 시공상의 번거로운 문제가 있어, 시공비가 많이 소요되는 것은 물론, 공사기간이 늘어나는 문제점이 내재되어 있다.However, the general reinforcement reinforcement is known to have excellent effect of delaying neutralization when deterioration of concrete is accelerated due to the use of gravel and sand of volcanic rock, but their composition is expensive and the deterioration state of the structure to be repaired and reinforced According to the selection of the appropriate products and the construction of these products in order to have a cumbersome problem in construction, a lot of construction costs, as well as the problem of increasing the construction period is inherent.
상기와 같은 문제점을 해결하고자 본원출원인은 1997년 4월 3일자(10-1997-0012276호)로 수중콘크리트 구조물 보수보강재를 출원하여 1999년 6월 22일자로 등록받은 바 있다.In order to solve the above problems, the applicant of the present application was filed on June 22, 1999 by applying for repair of underwater concrete structures as of April 3, 1997 (10-1997-0012276).

The main purpose is to provide reinforcement for underwater concrete structures using artificial aggregate.
또한, 다기능성 인조 골재를 사용함으로써, 비중, 흡수율, 실적율, 잔입자량, 마모율 및 안정성이 매우 우수한 특성을 보유하고 있으며, 콘크리트의 팽창붕괴를 발생시키는 Free-CaO의 함유량이 매우 적어 안정적이고, 유동성능 및 충진성능이 향상되고, 압축강도와 인장강도 역시 향상시킬 수 있는 다기능성 인조골재를 이용한 수중콘크리트 구조물 보수보강재를 제공하는데 다른 목적이 있다.In addition, by using a multi-functional artificial aggregate, it has characteristics of excellent specific gravity, absorption rate, performance rate, residual amount, wear rate and stability, and it is stable because the content of Free-CaO which causes expansion collapse of concrete is very small.

표 1에 도시된 바와 같이, 기존의 제강 슬래그와 같이 CaO, Fe2O3, SiO2가 주성분으로 이루고 있으나, F-CaO의 함량은 붕괴 위험성에 대한 한계치인 1%보다 낮은 0.09%와 0.15%로 나타난 것을 확인할 수 있다.As shown in Table 1, CaO, Fe 2 O 3 and SiO 2 are the main components as in conventional steelmaking slag, but the content of F-CaO is 0.09% and 0.15%, which is lower than the limit of the risk of collapse of 1%. You can see that appeared.
또한, 상기 풍쇄슬래그는 화학성분 및 함량은 기존 전로 슬래그와 유사하지만 융용 상태의 전로 슬래그를 다시 고압의 공기에 의해 반응시킴과 동시에 급냉 처리했기 때문에 그 광물의 존재상태는 다르게 나타난다. 즉, 풍쇄슬래그 중 CaO 성분은 거의 대부분 Fe2O3와 SiO2 성분과 반응하여 안정한 화합물 상태로 존재하여 전로슬래그에 비해 AB₂O₄즉, 스피널구조 광물생성량이 많아지는데, 이 스피널구조의 화학식은 CaO + Fe₂O₃= CaFe₂O₄로써, 서냉에 의한 광물의 분해현상도 없으므로 Free-CaO의 생성을 발생하지 않는다는 것을 알 수 있다.In addition, although the chemical composition and content of the wind slag slag is similar to the existing converter slag, the presence state of the mineral is different because the molten state of the converter slag is reacted with high-pressure air and quenched at the same time. That is, the CaO component of the wind slag reacts with the Fe 2 O 3 and SiO 2 components to exist in a stable compound state, and the amount of spinner mineral formation is higher than that of the converter slag. As CaO + Fe₂O₃ = CaFe₂O 없으므로, it can be seen that there is no decomposition of minerals due to slow cooling, and thus no generation of Free-CaO occurs.
또한, 표 2에 도시된 바와 같이, 풍쇄 슬래그 잔골재의 표건비중은 3.57, 굵은 골재는 3.48로 기존의 강모래, 해사 및 깬자갈 보다 비중이 높아 수중에 보수재를 타설할 경우 보수재의 충진성등 시공성을 높일 수 있는 것을 알 수 있었다.In addition, as shown in Table 2, the dry weight of the slag fine aggregate is 3.57, the coarse aggregate is 3.48, which has a higher specific gravity than the existing steel sand, sea sand and ground gravel. It can be seen that to increase.
이때, 상기 풍쇄 슬래그 골재의 흡수율은 약 0.90%로 기존의 깬자갈과 비슷한 수준을 보이고 있지만, 풍쇄 슬래그 잔골재의 흡수율은 약 0.5% 내외로 기존의 강모래나 해사보다 50% 정도 적은 흡수율을 보이고 있고, 이러한 낮은 흡수율은 콘크리트용 골재로 사용할 경우 우수한 품질을 확보하는데 이점이 있는 것을 확인할 수 있다.At this time, the absorption rate of the weathered slag aggregate is about 0.90%, showing a level similar to that of conventional crushed gravel, but the absorption rate of the weathered slag fine aggregate is about 0.5%, which is about 50% less than that of the existing steel sand or sea sand. , This low absorption rate can be seen that there is an advantage in ensuring excellent quality when used as aggregate for concrete.
또한, 상기 풍쇄 슬래그 잔골재의 경우 0.6mm 이하의 미립분이 적어 강모래 에 비해 65%로 강모래보다는 높은 실적율을 보이고 있고, 풍쇄 슬래그 골재의 경우 입형은 기존의 깬자갈과 같은 쇄석상이고, 입도도 표준입도 곡선을 벗어나 깬자갈보다 실적율이 다소 낮게 나타났다.In addition, the fine slag fine aggregates of less than 0.6mm in the case of the fine crushed slag aggregate shows 65% higher than that of the steel sand, and in the case of the crushed slag aggregate, the granular shape is the same as the crushed slag, and the grain size The performance was slightly lower than that of cracked gravel outside the standard particle size curve.
여기서, 골재의 마모율은 잔골재의 경우 KS기준은 없고, 골재의 경우에만 40%이하로 규정하고 있고, 풍쇄 슬래그 골재의 마모율은 약 16.91%로 양호하며, 골재의 안정성 KS기준은 잔골재는 10%이하, 골재의 경우는 12%로 규정하고 있고, 풍쇄 슬래그의 경우 잔골재는 2.6%, 골재는 6.5%로 모두 KS기준에 적정한 것임을 확인할 수 있다.Here, the wear rate of aggregate is no KS standard for fine aggregates, it is defined as 40% or less only for aggregates, and the wear rate of wind-slag slag aggregates is good at about 16.91%, and the stability of aggregates is 10% or less for fine aggregates. In the case of aggregate, 12% is specified, and in case of wind-slag slag, fine aggregate is 2.6% and aggregate is 6.5%.
또한, 상기 잔골재는 인조규사, 다기능성 인조골재를 혼합하여 조성한 것으로, 이는 인조규사 40 ~ 60 중량부, 다기능성 인조골재 40 ~ 60 중량부의 혼합비로 혼합하여 사용하는 것이다.In addition, the fine aggregate is made by mixing artificial silica, multi-functional artificial aggregate, which is used by mixing in a mixing ratio of 40 to 60 parts by weight of artificial silica sand, 40 to 60 parts by weight of multifunctional artificial aggregate.
이때, 상기 골재는 사용용도에 따라 선택적으로 첨가하여 사용하게 되며, 쇄석, 다기능성 인조골재를 혼합 조성하게 되는 것으로, 이는 쇄석 40 ~ 60 중량부, 다기능성 인조골재 40 ~ 60 중량부의 혼합비로 혼합하여 사용하게 되는 것이다.At this time, the aggregate is used to selectively add according to the use, it is to be used to mix the crushed stone, multi-functional artificial aggregate, which is 40 to 60 parts by weight of crushed stone, multi-functional artificial aggregate 40 to 60 parts by weight of the mixing ratio Will be used.
상기와 같은 조성물은 별도로 포장되어 현장에서 혼합하여 사용하게 되는데, 이는 사용용도에 따라 혼합비율을 선택적하여 사용하게 되는 것이다.Such a composition is separately packaged and used in the field to mix, which is to use the mixing ratio selectively depending on the intended use.
