Description
본 발명은 시멘트 모르타르 조성물 및 이를 이용한 블록 제조방법에 관한 것으로, 더욱 상세하게는 폐기되고 있는 바텀애쉬(bottom ash)를 사용한 친환경적인 폴리머 시멘트 모르타르 조성물, 이를 이용한 블록 제조방법 및 보투수성 포장 시공방법에 관한 것이다.
The present invention relates to a cement mortar composition and a block manufacturing method using the same, and more particularly, an environmentally friendly polymer cement mortar composition using a discarded bottom ash, a block manufacturing method and a water permeable paving method using the same. It is about.
현대 건축물 및 구축물에 쓰이는 수많은 구축재료는 산업사회의 발전과 함께 오염된 공해속에서 벗어나려는 인간의 욕구충족을 위해 보다 자연적인 소재의 연구가 시급한 시점이다. 그로 인하여 환경친화적인 구축재, 내외장재가 요구되고 있으며, 정부에서도 이를 적극 권장하고 있다. Numerous construction materials used in modern buildings and constructions are urgently needed to study more natural materials to meet the human needs to escape from polluted pollution with the development of industrial society. As a result, environmentally friendly construction materials and interior and exterior materials are required, and the government strongly recommends them.
일반적으로 블록은 크게 시멘트 블록과 점토 블록의 두 종류로 구분되고 있다. Generally, blocks are divided into two types: cement blocks and clay blocks.
시멘트 블록은 시멘트, 모래 및 자갈을 주원료로 하여 혼합 후 양생하여 제조하며, 재료의 배합 및 양생 조건에 따라 용도와 형태가 다양하다. 또한, 보행자용 도로의 미관 향상을 위해 인도에 보행자용 바닥 블록이나 경계 블록으로도 사용되고 있으며, 지역 및 특성화된 상권과 문화의 디자인 거리를 조성하는데 또한 그 활용범위를 점차적으로 확대되고 있다. 하지만, 시멘트 블록은 내구성에 대한 열화 등으로 인하여 하자가 발생되고 있다. Cement block is manufactured by curing after mixing with cement, sand and gravel as the main raw materials, and uses and forms vary depending on the composition and curing conditions of the material.

If the bottom ash content is less than 10% by weight, the initial strength of the composition is expressed, but the long-term strength and durability may be lowered.When the bottom ash content is more than 70% by weight, the workability and long-term strength of the composition are improved. However, it may delay the development of initial intensity.
상기 플라이애쉬는 잠재 수경성 특성, 장기 강도 발현 및 내구성 증진을 위하여 사용한다. 플라이애쉬의 중량비가 증가하면 초기 강도는 저하되나, 장기 강도 발현 및 내구성이 증가한다. 플라이애쉬 대신에 고로슬래그, 실리카분말 및 실리카흄을 사용할 수도 있다. 상기 플라이애쉬는 시멘트계 결합재에 대하여 1~10중량% 함유되는 것이 바람직하다. 플라이애쉬의 함량이 1중량% 미만일 경우에는 조성물의 초기강도는 발현되나 장기강도 및 내구성이 저하될 수 있고, 플라이애쉬의 함량이 10중량%를 초과하는 경우에는 조성물의 작업성 및 장기강도는 개선되나 초기강도 발현을 지연시킬 수 있다.The fly ash is used to enhance latent hydraulic properties, long-term strength development and durability. Increasing the weight ratio of fly ash lowers initial strength, but increases long-term strength development and durability. Instead of fly ash, blast furnace slag, silica powder and silica fume may be used. The fly ash is preferably contained 1 to 10% by weight based on the cement binder.

In addition to the excellent effect of reducing the performance of expressing high-performance performance, there is also the effect of implementing leveling and preventing cracks (crack). To the acrylic emulsion are added reactive special surfactants (sodium lauryl sulfate). When the acrylic emulsion is added, in particular, the adhesive strength and the breaking strength after curing are excellent, and the strength of the cement is enhanced to prevent desorption after adhesion and at the same time, the durability is very excellent. It is preferable that an acrylic emulsion is contained 85-98.5 weight part with respect to 100 weight part of polymeric binders. When the content of the acrylic emulsion is less than 85 parts by weight, the initial workability is improved but strength and durability may be lowered. When the content of the acrylic emulsion is more than 98.5 parts by weight, the strength and durability may be improved but the initial workability and economic efficiency may be poor. Can be.
상기 아크릴 부틸은 폴리머계 결합재의 점성 저하와 부착 및 인장 강도 개선을 위하여 사용된다. 아크릴 부틸은 폴리머계 결합재 100중량부에 대하여 0.5~10중량부 함유되는 것이 바람직하다. 아크릴 부틸의 함량이 0.5중량부 미만일 경우에는 재료분리는 발생되지 않으나 작업성, 부착 및 인장강도가 저하될 수 있고, 아크릴 부틸의 함량이 10중량부를 초과하는 경우에는 부착 및 인장강도는 개선되나 점성이 떨어져 재료분리가 발생될 수 있다.The acryl butyl is used to reduce the viscosity of the polymeric binder and to improve adhesion and tensile strength. It is preferable that acryl butyl is contained 0.5-10 weight part with respect to 100 weight part of polymeric binders. If the content of acryl butyl is less than 0.5 parts by weight, material separation does not occur, but workability, adhesion and tensile strength may be reduced. If the content of acryl butyl is more than 10 parts by weight, the adhesion and tensile strength may be improved, but the viscosity may be improved. This separation can cause material separation.
폴리머계 결합재로 아크릴 에멀젼 및 아크릴 부틸을 사용할 경우에는 조성물의 강도 및 내구성이 개선되나, 공기량 감소 및 작업성 개선을 위하여 고성능 감수제 및 소포제를 사용하는 것이 더욱 좋다. When the acrylic emulsion and acrylic butyl are used as the polymer-based binder, the strength and durability of the composition may be improved, but it is better to use a high performance water reducing agent and an antifoaming agent to reduce the amount of air and improve workability.
상기 감수제는 조성물의 물-시멘트비를 감소시켜 강도 및 내구성을 개선한다. 감수제의 종류에는 폴리카본산계, 멜라민계, 나프탈렌계 등이 있는데, 멜라민계 또는 나프탈렌계 감수제는 폴리카본산계 감수제에 비하여 강도 및 내구성의 개선 효과가 미약하고, 물-시멘트비의 저감 효과가 크지 않으며, 폴리머와의 혼화성이 나쁘다는 단점이 있으므로 바람직하게는 폴리카본산계 감수제를 사용하는 것이 바람직하다. 상기 감수제는 폴리머계 결합재 100중량부에 대하여 0.05~6중량부 함유되는 것이 바람직하다. The water reducing agent improves strength and durability by reducing the water-cement ratio of the composition. The types of water reducing agents include polycarboxylic acid, melamine, and naphthalene-based resins. Melamine-based or naphthalene-based water reducing agents are less effective in improving strength and durability than the polycarboxylic acid-based water reducing agents, and have no significant effect of reducing water-cement ratio. Since there is a disadvantage of poor compatibility with the polymer, it is preferable to use a polycarboxylic acid-based water reducing agent. It is preferable that the said water reducing agent is contained 0.05-6 weight part with respect to 100 weight part of polymeric binders.

Dimethyl silicone oil, polyorganosiloxane, fluorosilicone oil and the like may be used as the silicone antifoaming agent. As the fatty acid-based antifoaming agent, stearic acid, oleic acid or the like can be used. As the oil-based antifoaming agent, kerosene, animal or vegetable oil, castor oil, or the like can be used. The ester antifoaming agent may be used, such as solitol trioleate, glycerol monoricinoleate. As said oxyalkylene antifoamer, polyoxyalkylene, acetylene ether, polyoxyalkylene fatty acid ester, polyoxyalkylene alkylamine, etc. can be used. The alcohol-based antifoaming agent may be used glycol (glycol) and the like.
