As described above, the concrete composition improved in waterproofing and rustproofing performance using the concrete waterproofing agent of the present invention doubles the waterproof performance, durability and rustproofing performance of various concrete structures, thereby enhancing the convenience of construction, There is an advantage of easy maintenance.
아래에서는 본 발명에 따른 양호한 실시 예 및 실험 예를 상세히 설명한다.Hereinafter, preferred embodiments and experimental examples according to the present invention will be described in detail.
본 발명의 구체방수제를 이용하여 방수 및 방청성능을 향상시킨 콘크리트 조성물은 시멘트, 물, 골재, 구체방수제가 포함되되, 상기 구체방수제는 칼슘 디 아질산염(calcium nitrite), 에틸렌 비닐 아세테이트(ethylene vinyl acetate), 파라핀 왁스, 물, 스테아린산 아연(zinc stearate), 디카르 복시산 (oxalic acid), 푸탈산 수지 니스(phthalic resin varnish), 멜라민 설폰산염(melamine resin)을 포함하는 것을 특징으로 한다. The concrete waterproofing agent of the present invention includes calcium nitrite, ethylene vinyl acetate, and the like. The concrete waterproofing agent includes cement, water, , Paraffin wax, water, zinc stearate, oxalic acid, phthalic resin varnish, and melamine resin.
본 발명의 방수 및 방청성능을 향상시킨 콘크리트 조성물은 시멘트 100중량부에 대해 물 50 내지 100중량부, 골재 500 내지 1,000중량부, 상기 구체방수제 0.5 내지 2중량부, 수산화알루미늄 및 디노닐 나프틸 술폰산 암모늄염 혼합물 1 내지 5중량부, 바이오차 1 내지 5중량부를 포함하는 것을 특징으로 한다. The concrete composition of the present invention having improved waterproofing and rust-inhibiting properties is characterized by containing 50 to 100 parts by weight of water, 500 to 1,000 parts by weight of aggregate, 0.5 to 2 parts by weight of the concrete waterproofing agent, aluminum hydroxide and dinonylnaphthylsulfonic acid 1 to 5 parts by weight of an ammonium salt mixture, and 1 to 5 parts by weight of a biochip.
본 발명의 콘크리트 조성물에 있이 상기 구체방수제의 작용기작은 이하에서 설명한다. The functional groups of the concrete waterproofing agent in the concrete composition of the present invention are described below.
특히 본 발명의 콘크리트 조성물에는 수산화알루미늄 및 디노닐 나프틸 술폰산 암모늄염 혼합물이 첨가되는 바, 수산화알루미늄 및 디노닐 나프틸 술폰산 암모늄염은 중량비로 70:30 내지 80:20으로 혼합되는 것이 타당하다. In particular, aluminum hydroxide and dinonylnaphthylsulfonic acid ammonium salt mixture are added to the concrete composition of the present invention, and it is appropriate that the aluminum hydroxide and dinonylnaphtylsulfonic acid ammonium salt are mixed in a weight ratio of 70:30 to 80:20.
상기 수산화알루미늄은 시멘트 수화반응 과정에서 발생되는 열을 흡수하여 삼산화알루미늄과 물로 분해가 되는 것이다. 즉 수화열을 저감시켜 온도균열을 제어하도록 하는 것이다. 수산화알루미늄의 첨가에 의해 온도균열을 제어함으로써 페이스트의 방수성 및 방청성을 향상시키도록 하는 것이다. The aluminum hydroxide absorbs heat generated in the cement hydration reaction and decomposes into aluminum trioxide and water. That is, the hydration heat is reduced to control the temperature crack. By controlling the temperature crack by the addition of aluminum hydroxide, the waterproof property and the rust prevention property of the paste can be improved.
그런데 수산화알루미늄은 열을 흡수함과 동시에 삼산화알루미늄과 물로 분해되어 이렇게 생성된 물이 페이스트의 강도를 저하시킬 수 있는 문제가 있을 수 있다. 이에 본 발명에서는 수산화알루미늄에 더하여 디노닐 나프틸 술폰산 암모늄의 혼합물이 첨가되도록 하는 것이다.However, aluminum hydroxide absorbs heat and is decomposed into aluminum trioxide and water, so that the water thus produced may have a problem that the strength of the paste may be lowered. Thus, in the present invention, a mixture of ammonium dinonylnaphthylsulfonate in addition to aluminum hydroxide is added.
특히 이렇게 생성된 물에는 다량의 반응이온이 존재하여 페이스트를 중성화시킬 수 있는 문제가 있어 강도는 물론 내구성 저하의 요인으로 작용할 수 있는 바, 상기 디노닐 나프틸 술폰산 암모늄염이 더 포함되도록 하여 용출된 이온이 반응하는 것을 방지하며 동시에 디노닐 나프틸 술폰산 암모늄염에 의한 수분흡수를 통해 용출된 물 자체를 제거하도록 하는 것이다. 즉 수산화알루미늄 및 디노닐 나프틸 술폰산 암모늄염 혼합물의 첨가로 강도 및 내구성 저하없이 균열저항성을 향상시키도록 하는 것이다. Particularly, there is a problem that a large amount of reactive ion exists in the thus-produced water to neutralize the paste. As a result, it can act as a factor of strength and durability deterioration. As a result, the dinonylnaphthylsulfonic acid ammonium salt is further contained, And at the same time, the water itself is removed by absorption of water by the ammonium salt of dinonylnaphtylsulfonic acid. That is, the addition of the aluminum hydroxide and the dinonylnaphthylsulfonic acid ammonium salt mixture improves the crack resistance without deteriorating the strength and durability.
상기 조성 외에도 바이오차(Biochar)가 더 배합되는 바, 상기 바이오차는 바이오매스, 폐자원들을 무산소 또는 저산소 조건에서 열분해함으로서 얻어지는 다공성 고탄소물질이다. 우선 상기 바이오차가 첨가되면 페이스트에 존재하는 탄소를 고정시키게 되어 중성화의 원인이 되는 탄산의 발생을 제어하게 되는 것이다.In addition to the above composition, a biochar is further blended, which is a porous, high-carbon material obtained by pyrolyzing biomass and waste resources under anaerobic or hypoxic conditions. First, when the bio-car is added, carbon existing in the paste is fixed, thereby controlling the generation of carbonic acid which is a cause of neutralization.
즉 페이스트에서 발생하기 쉬운 중성화의 원인을 제거하여 내구성을 기할 수 있게 되는 것이다. 이에 더하여 바이오차의 높은 pH에 의해 페이스트에서의 pH를 상승시켜 중성화 환경자체를 제어하도록 한다. 결과적으로 바이오차의 첨가에 의해 중성화 원인물질의 발생을 제어하고 중성화 환경을 제어하여 페이스트에서의 내구성을 향상시킬 수 있게 되는 것이다. That is, it is possible to eliminate the cause of the neutralization which is likely to occur in the paste, thereby making it possible to provide durability. In addition, the pH of the paste is raised by the high pH of the biocha to control the neutralization environment itself. As a result, it is possible to control the neutralization environment by controlling the generation of the substance causing neutralization by the addition of the bio-tea, and to improve the durability in the paste.
상기 구체방수제는 칼슘 디 아질산염(calcium nitrite) 100중량부에 대해, 에틸렌 비닐 아세테이트(ethylene vinyl acetate) 50 내지 150중량부, 파라핀 왁스(paraffin wax) 50 내지 120중량부, 물 50 내지 120중량부, 스테아린산 아연(zinc stearate) 10 내지 50중량부, 디카르 복시산 (oxalic acid) 5 내지 30중량부, 푸탈산 수지 니스(phthalic resin varnish) 5 내지 20중량부, 멜라민 설폰산염(melamine resin) 5 내지 20중량부를 포함하는 것을 특징으로 한다. The concrete waterproofing agent may be prepared by mixing 50 to 150 parts by weight of ethylene vinyl acetate, 50 to 120 parts by weight of paraffin wax, 50 to 120 parts by weight of water with respect to 100 parts by weight of calcium diatomite, 10 to 50 parts by weight of zinc stearate, 5 to 30 parts by weight of dicarboxylic acid, 5 to 20 parts by weight of phthalic resin varnish, 5 to 20 parts by weight of melamine resin, 20 parts by weight.
칼슘 디 아질산염(calcium nitrite)은 본 발명의 방수제에 포함되어 방수성능을 그대로 유지하면서 방청성능을 증진시켜 콘크리트에 매립된 철근의 산화를 방지하여 철근 콘크리트의 부식을 억제할 수 있도록 한다. 즉 콘크리트 중의 철근을 부식으로부터 보호하는 작용을 하는 것으로서 콘크리트에 영향을 주지 않으면서 비교적 소량을 사용하여도 철근이나 강재의 부식을 방지하는 방청 작용을 하는 것이다.Calcium di-nitrite is included in the waterproofing agent of the present invention to improve the rust-preventive performance while maintaining the water-proofing performance, thereby preventing oxidation of the reinforcing bars embedded in the concrete, thereby suppressing the corrosion of the reinforced concrete. That is, it acts to protect the reinforcing bars in concrete from corrosion, and it has an anti-rust effect that prevents the corrosion of reinforcing bars or steel even if a relatively small amount of the reinforcing bars is used without affecting the concrete.
이러한 칼슘 디 아질산염(calcium nitrite)의 작용기작은 아질산이온(NO2-)이 철(Fe)로부터 용출된 철 이온(Fe++)과 반응하여 녹 성분인 수산화제이철[Fe(OH)3]의 생성을 차단하면서 안정한 화합물인 Fe2O3를 생성되게 된다. 이렇게 생성된 Fe2O3는 철 표면에 생긴 부식 지점에 피막을 형성하여 폐쇄시키므로 철의 부식 진행을 방지하게 되는 것이다. These functional groups little nitrite ion of calcium D nitrite (calcium nitrite) (NO 2-) to block the production of the iron ions (Fe ++) and reaction with the ferric hydroxide and melted component [Fe (OH) 3] dissolved from the iron (Fe) While Fe 2 O 3 , which is a stable compound, is produced. The resulting Fe 2 O 3 forms a film at the corrosion point formed on the iron surface and closes it, thereby preventing corrosion of iron.
상기 에틸렌 비닐 아세테이트(ethylene vinyl acetate)는 재분산성 분말수지(Redispersible Powders Polymer)로서 첨가되는 것으로, 상기 에틸렌 비닐 아세테이트(ethylene vinyl acetate)가 물에 첨가시 안정하게 분산되는 것으로서, 건조나 경화 후 물에 녹지 않는 비가역적인 폴리머 필름을 형성하게 된다. 즉, 시멘트 몰탈 또는 콘크리트 제조 시 페이스트 속에 균일하게 분산되어 시멘트 수화에 의한 시멘트 겔(Gel)을 형성함과 동시에 시멘트 겔 표면에 폴리머 입자가 침착(沈着)되어 불용성의 피막을 형성하거나 모세관, 겔 공극을 충진 하게 된다. 따라서 부재의 휨강도를 증가시키고, 페이스트 수축 등에 의해 생기는 크랙을 방지함과 동시에 페이스트의 건조 또는 경화과정에서 바인더로 작용함으로써 부착력, 콘크리트의 내마모성 및 유연성을 증가시킨다.The ethylene vinyl acetate is added as a redispersible powder polymer, and when the ethylene vinyl acetate is added to water, it is stably dispersed. When the ethylene vinyl acetate is added to water after drying or curing, Thereby forming an irreversible irreversible polymer film. That is, when the cement mortar or concrete is produced, it is uniformly dispersed in the paste to form a cement gel by cement hydration and polymer particles are deposited on the surface of the cement gel to form an insoluble film or a capillary, . Therefore, the bending strength of the member is increased, cracks caused by the shrinkage of the paste are prevented, and the binder acts as a binder in the drying or curing process of the paste, thereby increasing the adhesion, abrasion resistance and flexibility of the concrete.
상기 파라핀 왁스(paraffin wax)는 페이스트 내에서 충진성이 확보되도록 하여 밀실한 구조에 기해 방수성을 향상시키기 위한 구성에 해당한다. The paraffin wax corresponds to a composition for improving the waterproof property due to a tight structure by ensuring filling property in the paste.
상기 스테아린산 아연(zinc stearate)은 시멘트의 수화 반응에 따라 생기는 가용성의 수산화칼슘(Ca(OH)2)과 반응을 하여 수산기에 지방산기가 결합하여 발수성이 큰 고급지방산 칼슘을 생성하며, 발수성이 뛰어나므로 콘크리트 속의 모세관에 의한 수분의 흡수를 감소시키는 작용을 한다.The zinc stearate reacts with soluble calcium hydroxide (Ca (OH) 2 ) generated by the hydration reaction of the cement to form a higher fatty acid calcium having a high water repellency by bonding with a fatty acid group in the hydroxyl group and is excellent in water repellency, It acts to reduce the absorption of water by the capillary.
상기 디카르 복시산 (oxalic acid)은 분산제로서 기능을 하는 것으로 타 조성이 균일하게 분산되어 균일한 물성이 발현되도록 하는 것이다. The above-mentioned dicarboxylic acid functions as a dispersing agent so that the other composition is uniformly dispersed so as to exhibit uniform physical properties.
상기 푸탈산 수지 니스(phthalic resin varnish)는 칼슘 디 아질산염(calcium nitrite) 등 타 조성을 페이스트 내부로 침투시켜 밀착시키는 전색제로서 기능을 수행토록 하는 것이다. The phthalic resin varnish functions to function as a vehicle that penetrates into the paste and adheres the other composition such as calcium nitrite to the paste.
상기 멜라민 설폰산염(melamine resin)은 감수제로서 기능을 수행토록 하는 것이다. The melamine resin is to function as a water reducing agent.
이에 더하여 상기 구체방수제에서는 상기 조성 외에도 칼슘 디 아질산염(calcium nitrite) 100중량부에 대해, 폴리부타디엔 5 내지 15중량부, 팔라듐 1 내지 5중량부가 더 포함되도록 할 수 있다.In addition, in addition to the above composition, 5 to 15 parts by weight of polybutadiene and 1 to 5 parts by weight of palladium may be further added to 100 parts by weight of calcium nitrite in the concrete waterproofing agent.
이는 콘크리트 특히 표면의 조도불량 즉 표면에 공극이 발생되어 상기 공극으로 탄산, 수분 등의 유입을 방지토록 하기 위한 것이다. 이러한 표면공극은 페이스트의 알카리 성분과 금속성분 등이 반응하여 수소가스를 발생시켜 수소고용 능력이 과포화 되면 양생과정 등에서 수소가 페이스트 조직 외부로 방출되면서 콘크리트 표면에 공극, 균열 등이 형성됨에 기인한 것이다. 이렇게 발생된 표면공극은 표면조도를 불량하게 할 뿐 아니라 향후 방수 및 방청기능의 저하 포인트로서 작용을 하게 되는 것이다. This is intended to prevent the inflow of carbonic acid, water, etc. into the voids due to defects in the surface of the concrete, in particular, the occurrence of voids on the surface. This surface pore is caused by the formation of pores and cracks on the surface of the concrete as the hydrogen is released to the outside of the paste structure during the curing process as the hydrogen solubility is overproduced due to the reaction of the alkali component of the paste and the metal component, . The surface pores thus generated not only deteriorate the surface roughness but also act as a point of deterioration of the waterproofing and antirusting function in the future.
이에 본 발명에서는 폴리부타디엔이 첨가되도록 하는 바, 이러한 폴리부타디엔은 상기 팔라듐의 존재 하에 개방되는 이중결합을 가지며 이것은 개방형 이중결합에 수소의 고정을 용이하게 한다.In the present invention, polybutadiene is added so that the polybutadiene has a double bond that is opened in the presence of the palladium, which facilitates the fixation of hydrogen to the open double bond.
따라서 본 발명의 방수제에 폴리부타디엔과 팔라듐이 배합됨으로써 페이스트에서 발생되는 수소를 흡수토록 하여 표면공극의 형성을 제어토록 하는 것이다. Accordingly, by mixing polybutadiene and palladium in the waterproofing agent of the present invention, hydrogen generated in the paste is absorbed to control the formation of surface voids.
또한 본 발명에 있어 조성 중의 하나인 상기 푸탈산 수지 니스(phthalic resin varnish)는 내후성에서는 우수하나 콘크리트 페이스트의 알카리 환경에서 전색제로서 기능이 퇴색되는 문제가 있다. 이에 본 발명에서는 상기 푸탈산 수지 니스(phthalic resin varnish)를 첨가하되 푸탈산 수지 니스에는 전체중량 대비 실란이 5 내지 10중량부로 배합된 액체를 사용토록 하는 것이다.The phthalic resin varnish, which is one of the compositions in the present invention, is excellent in weatherability but has a problem that the function as a vehicle is discolored in the alkali environment of the concrete paste. In the present invention, the phthalic resin varnish is added, and the liquid containing the silane in the amount of 5 to 10 parts by weight based on the total weight is used as the finely divided resin varnish.
이와 같이 실란이 첨가됨으로써 알카리 환경에서도 전색제로서 기능이 퇴화되는 것을 방지토록 하는 것이다. 단, 실란이 배합범위를 상기와 같이 한정하는 이유는 10중량부를 초과하는 경우 푸탈산 수지 니스의 전색제로서 기능성이 알카리 환경에서도 발현될 수 있도록 하나, 콘크리트의 중성화 초래할 수 있으므로 상기와 같이 한정하는 것이다.
By adding silane in this way, it is possible to prevent degradation of function as a vehicle as a vehicle in an alkaline environment. However, the reason why the mixing range of silane is limited as described above is that when the amount is more than 10 parts by weight, the function as the vehicle of the varnish of the phthalic acid resin can be exhibited even in an alkaline environment, but the neutralization of the concrete may be caused, .
하기 표 1은 본 발명의 실험에 사용된 시료의 배합비를 나타내고 있다. Table 1 below shows the compounding ratio of the samples used in the experiments of the present invention.
상기 방수제는 칼슘 디 아질산염(calcium nitrite) 100중량부에 대해, 에틸렌 비닐 아세테이트(ethylene vinyl acetate) 100중량부, 파라핀 왁스(paraffin wax) 80중량부, 스테아린산 아연(zinc stearate) 30중량부, 디카르 복시산 (oxalic acid) 10중량부, 푸탈산 수지 니스(phthalic resin varnish) 10중량부, 멜라민 설폰산염(melamine resin) 10중량부가 포함된 실시 예 1과, 상기 실시 예 1에 더하여 폴리부타디엔 10중량부, 팔라듐 2중량부가 더 포함된 실시 예 2와, 실시 예 2와 조성이 동일하되 푸탈산 수지 니스에 실란이 전체중량 대비 5중량부가 배합된 실시 예 3을 가지고 실험을 하였다.100 parts by weight of ethylene vinyl acetate, 80 parts by weight of paraffin wax, 30 parts by weight of zinc stearate, 10 parts by weight of dicarboxylic acid, Example 1 containing 10 parts by weight of oxalic acid, 10 parts by weight of phthalic resin varnish and 10 parts by weight of melamine resin, and 10 parts by weight of polybutadiene 10 wt% And 2 parts by weight of palladium were further added and Example 3 in which the composition was the same as that in Example 2 but 5 parts by weight of silane was added to the total weight of the phthalic acid resin.
그리고 비교 예는 상기 콘크리트 배합은 동일하되 방수제가 혼합되지 않은 시료에 해당한다. 또한 실시 예 4는 실시 예 3과 동일한 방수제가 혼합되도록 하고 이에 더하여 수산화알루미늄 및 디노닐 나프틸 술폰산 암모늄염 혼합물 9(kg/㎥)이 더 배합된 것이며, 실시 예 5의 경우 실시 예 4와 동일하되 바이오차 9(kg/㎥)이 더 배합된 시료에 해당한다.In the comparative example, the concrete mixture is the same but the waterproofing agent is not mixed. In Example 4, the same waterproofing agent as in Example 3 was mixed, and further, an aluminum hydroxide and dinonylnaphtylsulfonic acid ammonium salt mixture 9 (kg / m 3) were further blended. In Example 5, the same as in Example 4 It corresponds to a sample with further mixing of 9 (kg / m3) of biocide.
이하 표 2는 각 시료에 대한 실험결과를 도시하고 있다. Table 2 below shows the experimental results for each sample.
KS F 4926에 규정된 방법에 따라 압축강도, 투수비와 물 흡수계수비를 측정하였으며, KS F 2561에 규정된 방법에 따라 방청률을 측정하였다. The compressive strength, permeability and water absorption coefficient ratios were measured according to the method specified in KS F 4926 and the rusting rate was measured according to the method specified in KS F 2561.
상기 표 2에서 보는 바와 같이 비교 예와 실시 예를 들에서 슬럼프는 동일하게 측정된 것으로 보아 본 발명에 있어 방수제를 첨가하더라도 시공성에 영향은 없는 것으로 판단된다. As shown in Table 2, the slump of Comparative Examples and Examples were measured in the same manner. Therefore, even if the waterproofing agent is added to the present invention, the slump is not influenced by the workability.
압축 강도 면에서 보면 비교 예 보다 본 발명의 방수제가 첨가되는 경우가 우수한 결과가 도출되는 것을 알 수 있는데 이는 본 발명의 방수제의 첨가에 의해 더욱 밀실한 구조가 도출됨에 기인한 것으로 판단된다. 또한 실시 예 1보다 실시 예 2의 경우가 압축강도 면에서 더욱 우수한 결과가 도출되는 것을 알 수 있는데 이는 방수제에 폴리부타디엔 및 팔라듐이 더 첨가됨으로써 페이스트에 발생하는 수소를 흡수하여 공극을 제어하는 것에 기인한 것으로 보인다. From the point of view of the compressive strength, it can be seen that the addition of the waterproofing agent of the present invention leads to an excellent result as compared with the comparative example. This is because the addition of the waterproofing agent of the present invention leads to a more closed structure. In addition, it can be seen that the results of Example 2 are better than those of Example 1 in terms of compressive strength. This is because polybutadiene and palladium are added to the waterproofing agent to thereby absorb hydrogen generated in the paste, Seems to have done.
방수성능 및 방청율에서 보면 비교예에 비해 본 발명의 방수제가 첨가된 실시 예들이 우수한 결과가 도출되는 것을 알 수 있다. 또한 실시 예 1보다 실시 예 2의 경우가 방수성능 및 방청율에서 우수한 결과가 도출되는 것을 알 수 있는데 이는 방수제에 폴리부타디엔 및 팔라듐이 더 첨가됨으로써 페이스트에 발생하는 수소를 흡수하여 특히 표면공극을 제어함에 의해 방수성은 물론 방청성도 우수하게 나타나는 것으로 판단된다.It can be seen that the examples in which the waterproofing agent of the present invention is added are superior to the comparative examples in terms of the waterproof performance and the rust prevention rate. In addition, it can be seen that the result of Example 2 is superior to that of Example 1 in waterproof performance and rust prevention rate. This is because addition of polybutadiene and palladium to the waterproofing agent absorbs hydrogen generated in the paste, It is judged that the waterproof property as well as the rustproofing property are exhibited.
또한 실시 예 2보다 실시 예 3의 경우가 방수성능 및 방청성에서 우수한 결과가 도출되는 것을 알 수 있는데 이는 실시 예 2의 경우 페이스트의 알카리 환경에서 푸탈산 수지 니스만을 조성으로 사용하는 것과 실시 예 3의 경우와 같이 푸탈산 수지 니스에 실란이 첨가되도록 하여 내알카리 환경이 조성된 경우의 차이로 보여진다. It can also be seen that the case of Example 3 is more excellent in the waterproof performance and the rustproofing property than that of Example 2, which is the case of using only the phthalic acid varnish composition in the alkaline environment of the paste in Example 2, As in the case where silane is added to the phos- phacic resin varnish to form an alkali-resistant environment.
또한 실시예 4 및 실시예 5의 경우가 타 실시예들보다 압축강도(28일)는 물론 방수성능 및 방청율에서 우수한 결과가 도출된 것을 알 수 있다.In addition, in the case of Examples 4 and 5, it was found that excellent results were obtained in terms of the waterproof performance and the rust prevention ratio as well as the compressive strength (28 days) of the other Examples.
실시예 4의 경우는 실시 예 3과 동일한 방수제가 혼합되도록 하고 이에 더하여 수산화알루미늄 및 디노닐 나프틸 술폰산 암모늄염 혼합물이 첨가된 시료로서 수산화알루미늄 및 디노닐 나프틸 술폰산 암모늄염 혼합물에 의해 균열을 제어함에 따라 압축강도가 우수한 결과로 도출된 것으로 판단되며 또한 방수성능 및 방청율에서 우수한 결과가 도출된 것을 알 수 있다. 또한 실시예 5의 경우 실시예 4와 동일하되 바이오차가 더 혼합되어 실시예 4의 경우보다 방수성능 및 방청율에서는 우수한 결과가 도출된 것을 알 수 있는데 이는 상기에서 언급한 바와 같이 바이오차에 의한 중성화의 방지에 의해 내구성이 강화된 결과로 보이며 이러한 결과는 시간이 경과에 따라 더욱 우수하게 발현될 것으로 판단된다.
In the case of Example 4, the same waterproofing agent as that in Example 3 was mixed, and furthermore, cracks were controlled by a mixture of aluminum hydroxide and dinonylnaphthylsulfonic acid ammonium salt as a sample to which a mixture of aluminum hydroxide and dinonylnaphtylsulfonic acid ammonium salt was added It is considered that the compressive strength is derived as an excellent result, and the excellent results are also obtained in the waterproof performance and the rust prevention ratio. In addition, in Example 5, the same results as those in Example 4 were obtained. However, it was found that more excellent results were obtained in the waterproof performance and rustproofing ratio than in Example 4, The results of this study are as follows. 1.
