The present invention relates to a method for producing polymer concrete using waste materials and industrial waste materials, and to polymer concrete produced by the method.
일반적으로, 건설폐자재, 산업폐자재(이하 '건설폐자재'로 칭함)는 아파트, 빌딩, 주택 등의 다양한 건축물의 재개발사업 또는 리모델링사업 등으로 인해 발생하고 있으며 이러한 건설폐자재의 70% 이상이 콘크리트 폐자재에 해당하고 있는 실정이다. In general, construction waste materials and industrial waste materials (hereinafter referred to as 'construction waste materials') are caused by redevelopment projects or remodeling projects of various buildings such as apartments, buildings, and houses, and more than 70% of such construction waste materials. This situation corresponds to the concrete waste materials.
이처럼 막대한 양의 콘크리트 폐자재를 재활용하지 못하고 매립 등의 방법에 의해 처리하는 경우에는 이는 국가적으로도 자연자원의 낭비 및 고갈로 이어질 수 있으며, 또한 경제적으로도 값비싼 폐기물 처리비용이 발생하고 매립지 부족에 따른 신설 매립지 확보에 거액의 세금이 투여되는 비생산적 공공투자가 불가피해지며, 사회적으로도 매립 폐자재로 인한 자연환경 오염이 야기되는 등의 커다란 문제점을 수반하게 되었다.If such a large amount of concrete waste material is not recycled and disposed of by landfilling, this may lead to waste and exhaustion of natural resources in the country, and economically expensive waste disposal costs and landfill shortages. As a result, it is inevitable that unproductive public investment in which a large amount of tax is applied will be inevitable to secure new landfill sites, and that social problems will also be caused by environmental pollution due to landfill waste.
이러한 문제점을 해결하기 위해, 매립되던 건설폐자재를 다시 안전한 건설 자재로 재활용할 수 있도록 '건설폐기물의 재활용촉진에 관한 법률'이 제정되어 동법 제2조제7호에 '순환골재'를 규정하고, 건설폐기물을 물리적 또는 화학적 처리과정 등을 거쳐 동법 제35조의 규정에 의한 품질기준에 적합하게 하여 KS 규격에 적합한 품질기준을 만족하는 콘크리트 폐자재를 순환골재로 규정하여, 품질기준에 만족하는 콘크리트 폐자재 순환골재는 적법하게 건설자재로 재활용 가능하도록 규정하고 있다.In order to solve these problems, the Law on the Promotion of Recycling of Construction Wastes was enacted to recycle used construction wastes back into safe construction materials. Concrete waste material that meets the quality standards in accordance with KS standards as concrete aggregates by making construction wastes conform to the quality standards according to Article 35 of the Act through physical or chemical treatment, etc. Material recycled aggregates are legally recyclable as construction materials.

상기 시멘트는 상기 건설폐자재와 동일한 중량부인 50:50의 비율로 혼합되며, 상기 시멘트의 중량부를 건설폐자재의 중량부와 동일하게 혼합하는 이유는 본 발명에 따른 건설폐자재를 활용한 폴리머 콘크리트 지지 구조체의 강도를 일반 콘크리트 지지 구조체의 강도와 동일하거나 더 향상된 강도를 갖도록 하기 위함으로써 50 중량부 미만으로 상기 시멘트를 건설폐자재의 중량부보다 적게 혼합하게 되면 콘크리트 지지 구조체의 강도가 저하될 수 있는 문제가 발생할 수 있고, 또한 50 중량부를 넘게 시멘트를 초과 혼합하여도 제조되는 콘크리트 지지 구조체의 강도 향상에는 큰 도움이 되지 않는 대신 오히려 제조 단가만이 높아지게 되므로, 제조 비용의 경제성을 고려하여 콘크리트 지지 구조체의 강도 유지를 위한 최적의 혼합비는 상술한 바와 같이 건설폐자재 순환골재와 시멘트를 동일한 중량비인 50:50으로 혼합하는 것이다.The cement is mixed at a ratio of 50:50, which is the same weight part as the construction waste material, and the reason for mixing the weight part of the cement with the weight part of the construction waste material is the polymer concrete using the construction waste material according to the present invention. When the cement is mixed with less than 50 parts by weight of the construction waste material to reduce the strength of the support structure to the same or better than that of the general concrete support structure, the strength of the concrete support structure may be reduced. Problems may occur, and the concrete support structure produced by mixing more than 50 parts by weight of cement is not a great help to improve the strength of the concrete support structure, but rather, only the manufacturing cost is increased, considering the economic cost of manufacturing support The optimum mixing ratio for maintaining the strength of the structure is as described above. Construction waste materials circulating aggregate and cement are mixed at the same weight ratio of 50:50.
상기 S2 단계인 건설폐자재 순환골재와 시멘트가 동일한 중량부로 혼합되는 혼합 공정이 수행되면, 다음으로 혼합된 건설폐자재 순환골재 및 시멘트의 혼합물에 사용수를 투입하여 혼합하게 되는 사용수 투입단계(S3)를 수행하게 된다.When the mixing process of mixing the construction waste material recycled aggregate and cement in the same weight part is performed in step S2, the use water input step of mixing and mixing the used waste water into the mixture of the mixed construction waste recycled aggregate and cement next ( S3) is performed.
본 단계(S3)에서, 상기 사용수는 상기 건설폐자재 순환골재 및 시멘트가 혼합된 혼합물 100 중량부에 7~10 중량부의 비율로 투입되게 되는데, 사용수가 7 중량부 미만으로 투입되면 결합재인 시멘트가 건설폐자재 순환골재의 표면에 부착되는 부착력이 저하되는 문제점이 있게 되고, 반면 10 중량부를 넘게 초과 투입되면 결합재인 시멘트의 일부가 순환골재의 표면으로부터 유동되어 제조되는 폴리머 콘크리트의 강도가 저하되는 문제점이 있게 된다. In this step (S3), the use water is put in a ratio of 7 to 10 parts by weight to 100 parts by weight of the mixture of the construction waste material recycled aggregate and cement, cement used as a binder when the water used is less than 7 parts by weight There is a problem that the adhesive force attached to the surface of the construction waste recycled aggregates is reduced, whereas when more than 10 parts by weight is added, a portion of cement as a binder flows from the surface of the recycled aggregates, thereby decreasing the strength of the polymer concrete produced. There is a problem.
또한, 본 S3 단계에서 투입되는 사용수의 상기의 중량비 범위는 후술하는 폴리머의 투입 중량비와도 밀접한 연관성을 갖게 되는데, 이에 대한 자세한 설명은 폴리머의 설명 단락에서 자세하게 후술하기로 한다.In addition, the weight ratio range of the water used in the step S3 has a close relationship with the input weight ratio of the polymer to be described later, a detailed description thereof will be described later in detail in the description section of the polymer.
상기 S3 단계를 통해 건설폐자재 순환골재 및 시멘트에 상기 사용수를 투입하여 반죽 형태로 혼합하는 공정을 수행함과 함께, 여기에 탄성을 갖는 폴리머를 첨가하여 혼합하는 폴리머 혼합단계(S4)를 수행하게 된다.Through the step S3 is carried out the process of mixing the dough into the construction waste material recycled aggregate and cement into the form of dough, and adding a polymer having elasticity to the mixing step (S4) to perform do.
본 단계(S4)에서, 상기 폴리머는 상기 S3 단계에서 투입되는 상기 사용수 100 중량부에 30~50 중량부의 비율로 첨가되어 투입된다. 상기 폴리머는 결합재인 상기 시멘트와 함께 상기 건설폐자재 순환골재에 결합되는 결합재로서, 건축물 지지 구조체에 폴리머의 유연성 및 탄성을 부여하여 건축물 지지 구조체의 물성을 더욱 개선하는 조성물로서, 상기 건설폐자재 순환골재, 시멘트, 폴리머가 상호 결합함으로써 폴리머 콘크리트가 제조되는 것이다.In this step (S4), the polymer is added in a proportion of 30 to 50 parts by weight to 100 parts by weight of the water used in the step S3. The polymer is a binder that is bonded to the construction waste recycling aggregate with the cement as a binder, the composition to impart flexibility and elasticity of the polymer to the building support structure to further improve the physical properties of the building support structure, the construction waste material circulation Aggregate, cement, and polymer are combined to make polymer concrete.
본 단계(S4)에서의 상기 폴리머로는 불포화 폴리에스테르 수지, 폴리우레탄 수지, 폴리에틸렌 수지, 아크릴레이트 수지, 에폭시 수지, 우레아 수지, 페놀 수지 중에서 선택되는 적어도 어느 하나 이상이 적용될 수 있으며, 가장 바람직하게는 점도가 200~500cP(=0.2~0.5Paㆍs, 25℃ 기준)인 액상의 아크릴레이트가 혼성중합체로 적용된 폴리머이며, 본 발명에 적용되는 상기 폴리머 역시 액상의 아크릴레이트이다.At least one selected from unsaturated polyester resins, polyurethane resins, polyethylene resins, acrylate resins, epoxy resins, urea resins, and phenol resins may be applied as the polymer in this step (S4), most preferably. Is a polymer in which a liquid acrylate having a viscosity of 200 to 500 cP (= 0.2 to 0.5 Pa · s at 25 ° C.) is applied as a copolymer, and the polymer to be applied to the present invention is also a liquid acrylate.
본 단계(S4)에서, 상기 폴리머는 상기 S3 단계에서 투입되는 상기 사용수 100 중량부에 30~50 중량부의 비율로 첨가되어 투입되는데, 상기 폴리머가 30 중량부 미만으로 첨가되어 투입되면 결합재로서의 결합력이 약하게 되어 목적하는 강도 및 수밀성 등의 물성 향상을 기대하기 어렵고, 50 중량부를 넘게 초과하여 투입되면 강도, 유연성 등의 물성은 우수해지나 제조비용이 높아지고 성형성이 저하되는 중요한 문제점이 있으며, 특히 상기 폴리머는 고가의 조성물질이어서 물성 향상의 기능성 대비 폴리머 투입 경제성을 고려하여 최적의 첨가 및 투입 중량 범위를 도출하여야 한다. In this step (S4), the polymer is added in a proportion of 30 to 50 parts by weight to 100 parts by weight of the water used in the step S3, the polymer is added to less than 30 parts by weight of the binding force as a binder This weakness makes it difficult to expect improved physical properties such as strength and watertightness, and when it is added in excess of 50 parts by weight, the physical properties such as strength and flexibility are excellent, but the manufacturing cost is high and moldability is deteriorated. Since the polymer is an expensive composition, it is necessary to derive an optimum addition and input weight range in consideration of the polymer injection economics compared to the function of improving physical properties.
또한, 상기 S3 단계에서 투입되는 상기 사용수 100 중량부 대비 30~50 중량부의 비율로 첨가되어 투입되는 본 단계(S4)의 상기 폴리머의 투입 중량비 범위가 상기 S3 단계에서 투입되는 사용수의 중량비를 기준으로 하여 첨가 혼합하는 이유는, 건설폐자재 순환골재, 시멘트에 투입되는 사용수가 본 단계(S4) 이후에 수행되는 단계를 수행하면서 증발함에 따라 증발된 사용수가 위치하던 공간으로 상기 폴리머가 자리잡게 되면서 폴리머 콘크리트의 강도 및 수밀성, 탄성 및 유연성을 높이게 되므로, 상기 폴리머의 투입 중량비 범위는 상기 사용수의 투입 중량비 범위와 더불어 본 발명에 따른 건설폐자재를 활용한 폴리머 콘크리트의 물성을 향상하기 위한 매우 중요한 조성 비율이며, 동시에 상기 폴리머의 투입 중량비 범위의 기준이 되는 조성물질은 상기 건설폐자재 순환골재 및 시멘트가 혼합되는 각각의 중량이 기준이 되는 것이 아니라 투입되는 사용수의 중량비를 기준으로 하여 상기 폴리머의 최적의 첨가, 투입 중량비 범위를 도출하게 되는 것이다.In addition, the weight ratio of the water used in the step S3 is added to the weight ratio range of the polymer of the present step (S4) is added in a ratio of 30 to 50 parts by weight with respect to 100 parts by weight of the water used in the step S3. The reason for the addition and mixing as a reference is that the polymer is placed in the space where the evaporated water was located as the evaporation of the waste water used in the construction waste material recycled aggregate and cement is performed after the step S4 is performed. While increasing the strength and watertightness, elasticity and flexibility of the polymer concrete, the weight ratio range of the polymer is very good for improving the physical properties of the polymer concrete using the construction waste material according to the present invention in addition to the input weight ratio range of the water used. The compositional quality, which is an important compositional ratio and at the same time the basis for the range of the input weight ratio of the polymer, is Seolpye will by the material recycled aggregate and based on the weight of the can used in which each weight is introduced not as a reference to be a cement mixture that will elicit the optimum addition, input weight range of the polymer.
상기 S4 단계인 폴리머 혼합단계를 거친 폴리머 콘크리트에 폴리머 콘크리트의 결합, 기능, 물성 등의 향상을 위한 첨가제가 첨가되는 첨가제 첨가단계(S5)를 수행하게 된다. Performing the additive addition step (S5) in which the additive for improving the bonding, function, physical properties, etc. of the polymer concrete to the polymer concrete, the polymer mixing step, the step S4 is performed.
본 단계(S5)에서 첨가되는 첨가제에는 텍사놀(Texanol), 부틸 카비톨(Butyl Carbitol), 부틸 셀로솔브(Butyl Cellosolve) 중 어느 하나 또는 그 혼합물이 적용된 가소제와, 비이온 중합분산제, 폴리 인산나트륨염 중 어느 하나 또는 그 혼합물이 적용된 분산제와, 통상적인 실리콘 소포제가 적용된 소포제가 각각 첨가된다. 상기 가소제 및 분산제와 소포제는 투입된 상기 사용수 100 중량부에 가소제 및 분산제는 45 ~ 55 중량부, 소포제는 95 ~ 105 중량부의 중량 비율로 첨가된다. 본 발명의 실시예의 상기 S5단계에서는 상기 사용수 100 중량부에 가소제 및 분산제는 50 중량부, 소포제는 100 중량부의 중량 비율로 첨가되어 혼합된다. 상기 가소제 및 분산제와 소포제의 상기 중량부 범위는, 상기 폴리머의 중량비 범위와 마찬가지로, 상기 사용수가 S4단계 이후에 수행되는 단계를 수행하면서 증발함에 따라 증발된 사용수가 위치하던 공간으로 상기 폴리머가 자리잡게 되면서 폴리머 콘크리트의 강도 및 수밀성, 탄성 및 유연성을 높이도록 상기 가소제, 분산제 및 소포제가 각각의 기능을 충실하게 수행할 수 있도록 하는 바람직한 중량부 범위이다. 상기 가소제 및 분산제, 소포제가 각각의 중량부 미만으로 혼합되면 가소성, 분산성, 소포 기능이 미흡해지고, 각각의 중량부를 초과하여 혼합되면 폴리머 콘크리트의 강도 및 수밀성 등의 물성이 저하될 수 있다.The additive added in this step (S5) includes a plasticizer to which any one or a mixture of texanol, butyl carbitol, and butyl cellosolve is applied, a nonionic polymerization dispersant, and poly sodium phosphate. A dispersant to which one or a mixture of salts is applied and an antifoaming agent to which a conventional silicone antifoaming agent is applied are added, respectively. The plasticizer, the dispersant, and the antifoaming agent are added at a weight ratio of 45 to 55 parts by weight of the plasticizer and the dispersant, and 95 to 105 parts by weight of the antifoaming agent. In the step S5 of the embodiment of the present invention, 50 parts by weight of a plasticizer and a dispersant are added to 100 parts by weight of the water used, and an antifoaming agent is added by mixing in a weight ratio of 100 parts by weight. The weight part range of the plasticizer and the dispersant and the antifoaming agent, like the weight ratio range of the polymer, allows the polymer to settle in the space where the evaporated water is located as the water is evaporated while performing the step performed after the step S4. While the plasticizer, the dispersant and the antifoaming agent to perform the respective functions faithfully to increase the strength and water tightness, elasticity and flexibility of the polymer concrete while being a preferred weight range. When the plasticizer, the dispersant, and the antifoaming agent are mixed in less than each part by weight, plasticity, dispersibility, and defoaming function may be insufficient. When the plasticizer, the dispersant, and the antifoaming agent are mixed in excess of each part, physical properties such as strength and water tightness of the polymer concrete may be reduced.
