본 발명의 특징 및 이점들은 첨부도면에 의거한 다음의 상세한 설명으로 더욱 명백해질 것이다. 이에 앞서, 본 명세서 및 청구범위에 사용된 용어나 단어는 발명자가 그 자신의 발명을 가장 최선의 방법으로 설명하기 위해 용어의 개념을 적절하게 정의할 수 있다는 원칙에 입각하여 본 발명의 기술적 사상에 부합하는 의미와 개념으로 해석되어야만 한다. The features and advantages of the present invention will become more apparent from the following detailed description based on the accompanying drawings. Prior to this, the terms or words used in the present specification and claims are defined in the technical spirit of the present invention on the basis of the principle that the inventor can appropriately define the concept of the term in order to explain his invention in the best way. It must be interpreted to mean meanings and concepts.
이하, 본 발명의 실시 예에 따른 보습성 콘크리트 블록 및 이의 제조방법을 상세하게 설명한다.Hereinafter, a moisturizing concrete block according to an embodiment of the present invention and a manufacturing method thereof will be described in detail.
먼저, 본 발명의 실시 예에 따른 보습성 콘크리트 블록을 상세하게 설명한다.First, the moisturizing concrete block according to the embodiment of the present invention will be described in detail.
본 실시 예에 따른 보습성 콘크리트 블록은 중금속과 같은 유해물질이 용출되어 우수나 지하수, 토양의 오염이 방지될 수 있도록 보도나 차도 등의 포장재로 사용된다.Moisturizing concrete block according to this embodiment is used as a pavement or roadway pavement so that harmful substances such as heavy metals can be eluted to prevent rainwater, groundwater, soil contamination.
이를 위하여 보습성 콘크리트 블록은 폴리아크릴산나트륨, 메타크릴산, 글리세린, 공기 연행제, 활성탄, 시멘트, 골재 및 물을 포함한다.Moisturizing concrete blocks for this purpose include sodium polyacrylate, methacrylic acid, glycerin, air entrainer, activated carbon, cement, aggregate and water.
구체적으로 보습성 콘크리트 블록은 보습성이 향상되고 우수나 지하수가 정화될 수 있도록 시멘트 20 내지 25 중량%, 골재 69 내지 74 중량%, 물 4 내지 6 중량%, 폴리아크릴산나트륨 0.1 내지 0.5 중량%, 메타크릴산 0.05 내지 0.1 중량%, 글리세린 0.05 내지 0.1 중량%, 공기 연행제 0.05 내지 0.1 중량%, 활성탄 0.1 내지 0.5 중량%를 포함한다.Specifically, the moisturizing concrete block is 20 to 25% by weight of cement, 69 to 74% by weight of aggregate, 4 to 6% by weight of water, 0.1 to 0.5% by weight of sodium polyacrylate, to improve moisture retention and to purify rainwater or groundwater. 0.05 to 0.1% by weight methacrylic acid, 0.05 to 0.1% by weight glycerin, 0.05 to 0.1% by weight air entrainer, 0.1 to 0.5% by weight activated carbon.
여기서, 보습성 콘크리트 블록은 폴리아크릴산나트륨에 의해 수분의 흡수가 증가되어 보습성이 개선되고, 메타크릴산과 글리세린에 의해 폴리아크릴산나트륨의 수분 흡수가 천천히 이루어질 수 있도록 하여 투수성이 유지된다. 즉, 보습성 콘크리트 블록은 메타크릴산과 글리세린에 의해 폴리아크릴산나트륨이 수분을 흡수할 때 수분 흡수가 천천히 진행되므로, 투수와 수분 흡수가 함께 진행된다.Here, the moisture-absorbing concrete block is the moisture absorption is increased by the sodium polyacrylate is improved moisture retention, the water absorption of the sodium polyacrylate by the methacrylic acid and glycerin can be made to be slow, the water permeability is maintained. In other words, the moisture-absorbing concrete block has a slow water absorption when the sodium polyacrylate absorbs water by methacrylic acid and glycerin, so that the permeability and water absorption proceeds together.
이때, 본 실시 예에 따른 보습성 콘크리트 블록은 폴리아크릴산나트륨의 함량이 0.1 중량% 미만인 경우에 메타크릴산과 글리세린에 의해 그 수분 흡수 특성이 전혀 나타나지 않아 보습성이 저하되며, 폴리아크릴산나트륨의 함량이 0.5 중량% 초과인 경우 블록의 pH 농도가 증가하게 되어 수질 및 토양이 오염된다.At this time, the moisture-containing concrete block according to the present embodiment, when the content of sodium polyacrylate is less than 0.1% by weight, its moisture absorption properties are not shown by methacrylic acid and glycerin at all, so that the moisture retention is lowered, and the content of sodium polyacrylate If it is more than 0.5% by weight, the pH concentration of the block increases, contaminating the water quality and the soil.
또한, 본 실시 예에 따른 보습성 콘크리트 블록은 메타크릴산 및 글리세린 각각의 함량이 0.05 중량% 미만인 경우에 폴리아크릴산나트륨의 수분의 흡수가 단시간에 이루어져 블록의 공극이 수분으로 채워져 투수성이 전혀 나타나지 않으며, 메타크릴산 및 글리세린 각각의 함량이 0.1 중량% 초과인 경우 폴리아크릴산나트륨의 수분 흡수율이 저하되어 보습성이 현저하게 저하된다.In addition, the moisture-retaining concrete block according to the present embodiment, when the content of each of methacrylic acid and glycerin is less than 0.05% by weight of water absorption of sodium polyacrylate in a short time is filled with water pores of the block is not water-permeable at all In addition, when the content of each of methacrylic acid and glycerin is more than 0.1% by weight, the water absorption of sodium polyacrylate is lowered and the moisture retention is remarkably lowered.
또한, 본 실시 예에 따른 보습성 콘크리트 블록은 공기 연행제에 의해 콘크리트를 배합하는 과정에서 미세한 공기포가 발생되어 공극이 형성이 효과적으로 이루어지게 된다. 이때, 보습성 콘크리트 블록은 공기 연행제의 함량이 0.05 중량% 미만인 경우 공극율이 저하되어 보습성 및 투수성이 저하되며, 공기 연행제의 함량이 0.1 중량% 초과인 경우 공극율이 너무 증가하여 내구성이 저하된다.In addition, the moisturizing concrete block according to the present embodiment is a fine air bubbles are generated in the process of mixing the concrete by the air entrainer, the voids are effectively formed. At this time, when the content of the air entrainer is less than 0.05% by weight, the porosity is lowered and the moisture retention and permeability are lowered. If the content of the air entrainer is more than 0.1% by weight, the porosity is too high to increase durability. Degrades.
또한, 본 실시 예에 따른 보습성 콘크리트 블록은 물이 투수되는 과정에서 활성탄에 의해 오염물질 및 중금속이 흡착되어 분해되므로, 블록을 투과한 물이 자연 정화된다.In addition, since the pollutants and heavy metals are adsorbed and decomposed by activated carbon in the process of water permeation, the water-permeable concrete block according to the present embodiment naturally purifies water that has passed through the block.
또한, 본 실시 예에 따른 보습성 콘크리트 블록은 시멘트의 함량이 20 중량% 미만인 경우 내구성이 현저하게 저하되며, 시멘트의 함량이 25 중량% 초과인 경우 pH가 증가되어 오염물질이 많이 유출된다.In addition, the moisture-retaining concrete block according to the present embodiment is significantly reduced durability when the content of cement is less than 20% by weight, and when the content of the cement is more than 25% by weight, the pH is increased and a lot of pollutants flow out.
또한, 본 실시 예에 따른 보습성 콘크리트 블록은 골재의 함량을 64 내지 74 중량%로 혼합하는 것은 공극율이 10~15%로 유지되도록 하여 충분한 투수성을 확보하기 위함이다. 여기서, 골재의 입경이 1.5mm 내지 3mm인 것을 사용하는 것이 바람직하며, 이때, 골재의 입경이 1.5mm미만이면 공극율이 현저하게 저하되어 투수성이 현저하게 저하되어 물의 투수가 전혀 이루어지지 못하고, 입경이 3mm를 초과하게 되면 표면이 매끄럽지 못하고 내구성이 저하된다.In addition, the moisturizing concrete block according to the present embodiment is to mix the content of the aggregate at 64 to 74% by weight to ensure sufficient permeability to maintain the porosity at 10 to 15%. Here, it is preferable to use a particle size of the aggregate is 1.5mm to 3mm, in this case, if the particle size of the aggregate is less than 1.5mm, the porosity is significantly reduced and the water permeability is significantly reduced, water permeability is not achieved at all, the particle size If it exceeds 3mm, the surface is not smooth and durability is degraded.
또한, 본 실시 예에 따른 보습성 콘크리트 블록은 물의 함량이 4 중량% 미만인 경우 성형기로 가압하여 형성하여도 혼합물들이 접합되지 않게 되며, 물의 함량이 6 중량% 초과인 경우 폴리아크릴산나트륨, 메타크릴산 및 글리세린이 희석될 뿐만 아니라, 성형기로 가압하여 성형할 때 공극이 잘 이루어지지 못하여 보습성 및 투수성이 현저하게 저하된다.In addition, the moisturizing concrete block according to the present embodiment, even if the water content is less than 4% by weight formed by pressing with a molding machine, the mixture is not bonded, when the water content is more than 6% by weight sodium polyacrylate, methacrylic acid And not only the glycerin is diluted, but also poorly formed when pressurized by a molding machine, the moisture retention and water permeability are significantly reduced.
다음으로 실시예 및 비교예를 통하여 본 실시 예에 따른 보습성 콘크리트 블록을 보다 상세히 설명하고자 한다. 이들 실시예 및 비교예는 오로지 본 발명을 보다 구체적으로 설명하기 위한 것으로, 본 발명의 요지에 따라 본 발명의 범위가 이들 실시예에 의해 제한되지 않는다는 것은 당업계에 통상의 지식을 가진 자에게 있어서 자명할 것이다.Next will be described in more detail the moisturizing concrete block according to this embodiment through Examples and Comparative Examples.
