본 발명은 시멘트를 전혀 사용하지 않고, 점토 포러스 콘크리트를 만드는 '시멘트 무첨가형 환경친화성 점토 포러스 콘크리트 조성물'에 관한 것이다.The present invention relates to a 'cement-free environmentally friendly clay porous concrete composition' which makes clay porous concrete without using cement at all.

더욱 구체적으로, 천연상태의 점토에 산업부산물인 고로슬래그와 고로슬래그의 약한 자경성을 촉진시키기 위한 알칼리성 자극제(NaOH, NaCl, CaCl2, KOH, Ca(OH)2, CaSO4, 규산소다)를 적절히 첨가한 후 물로 비벼 형성되어진 점토 페이스트를 굵은 골재에 둘러쌈으로서 골재를 서로 접착시켜 조성물을 다공질화 한 연속공극 경화체로 시멘트를 전혀 사용하지 않고 필요한 공극과 소정의 강도를 확보하며 동시에 다양한 점토의 사용으로 환경친화적인 색상을 구현할 수 있고 색상의 조절도 가능한 "시멘트 무첨가형 환경친화성 점토 포러스 콘크리트 조성물"에 관한 것이다.More specifically, alkaline stimulants (NaOH, NaCl, CaCl 2 , KOH, Ca (OH) 2 , CaSO 4 , Sodium Silicate) to promote weak magnetic hardening of blast furnace slag and blast furnace slag which are industrial by-products in natural clay It is a continuous pore cured body in which the aggregates are bonded to each other and the aggregates are adhered to each other by enclosing the clay paste, which is formed by mixing with water after being added properly, to secure the necessary voids and predetermined strength without using cement at the same time. The present invention relates to a "cement-free environmentally friendly clay porous concrete composition", which can realize environmentally friendly color and adjust color.

일반적으로 보통콘크리트는 잔골재와 굵은 골재가 시멘트 페이스트 내에 분산이 되어 있는 형태로서 공극이 작고 조직이 밀실한데 반해 포러스콘크리트는 굵은 골재가 시멘트 페이스트를 둘러쌈으로서 골재를 서로 접착시켜 내부에 공극이 많아 물이 통할 수 있는 연속공극이 형성되어 있는 다공성 콘크리트이다.Generally, the fine concrete and coarse aggregate are dispersed in cement paste, and the voids are small and the structure is tight, whereas for porous concrete, the coarse aggregate surrounds the cement paste so that the aggregates adhere to each other, so It is porous concrete in which continuous pores are formed.

이러한 포러스콘크리트는 내부의 연속 공극으로 인해 식생용, 투수용, 흡음용, 수질정화용등 통상의 보통콘크리트와는 다른 용도에 다양하게 이용되고 있으며, 환경 부하 저감형 재료로서 기능이 인식되면서 수요도 점차 늘어나 용도의 전개가 주목되고 있다.Due to the continuous voids inside, such porous concrete is used in a variety of applications different from ordinary concrete such as vegetation, water permeation, sound absorption, water purification, etc. The expansion of the use is attracting attention.

하지만, 포러스콘크리트의 사용 재료인 시멘트는 제조과정 중 이산화탄소와 황화합물이 생성되고 재생이 불가능하여 지구환경 부하를 증가시키고 있어 포러스콘크리트의 환경친화적인 재료로서 기능을 약화시키고 있으며, 시멘트가 가지고 있는 고유의 회색빛으로 인해 다양한 색의 변화를 주기 위해서는 별도의 착색 작업이 필요로 하는 문제점을 안고 있다.However, cement, which is the material used for porous concrete, is increasing the global environmental load because carbon dioxide and sulfur compounds are produced and cannot be recycled during the manufacturing process, thus weakening the function as environmentally friendly material of porous concrete. Due to the gray color has a problem that requires a separate coloring work in order to change a variety of colors.

따라서 본 발명자는 포러스콘크리트의 본래의 기능은 유지하면서 사용재료의 문제점을 해결하기 위하여 지구환경 부하를 증가시키는 시멘트를 사용한 페이스트 대신에 매장량이 풍부하고 가공이 필요치 않은 점토에 산업부산물인 고로슬래그와 고로슬래그의 약한 자경성을 촉진시키기 위한 알칼리성 자극제(NaOH, NaCl, CaCl2, KOH, Ca(OH)2, CaSO4, 규산소다)를 단일 혹은 혼용 첨가한후 물로 비벼 형성되어진 점토 페이스트를 굵은골재에 둘러쌈으로서 골재를 서로 접착시켜 포러스 조성물이 시멘트를 사용하지 않고서도 다공질의 연속공극과 소정의 강도를 확보함과 동시에 다양한 점토의 사용으로 환경친화적인 색상을 구현할 수 있고색상의 조절이 가능한"환경친화형 점토 포러스콘크리트 조성물"을 개발하게 되었다.Therefore, the inventors of the present invention found that blast furnace slag and blast furnace, which are industrial by-products in clay which is rich in reserve and do not need processing, instead of paste using cement, which increases the global environmental load in order to solve the problems of the materials used while maintaining the original function of the porous concrete. Clay paste, which was formed by mixing with water, was added to coarse aggregate after adding single or mixed alkaline stimulants (NaOH, NaCl, CaCl 2 , KOH, Ca (OH) 2 , CaSO 4 , Soda Silicate) to promote the weak hardness of slag. By enclosing the aggregates together, the porous composition can secure porous continuous voids and predetermined strength without using cement, and can realize eco-friendly colors by using various clays and can control colors. "Affinity clay porous concrete composition" has been developed.

본 발명의 목적은 천연상태의 점토에 산업부산물인 고로슬래그와 고로슬래그의 약한 자경성을 촉진시키기 위한 알칼리성 자극제(NaOH, NaCl, CaCl2, KOH, Ca(OH)2, CaSO4, 규산소다)를 단일 혹은 혼용 첨가한 후 물로 비벼 형성되어진 점토 페이스트를 굵은 골재에 피복 하여 골재가 서로 접착되어 조성물을 다공질화한 연속공극 경화체로 시멘트를 전혀 사용하지 않고 필요한 공극과 소정의 강도를 확보하며 다양한 점토를 사용함으로서 색상의 조절이 가능한 "환경친화형 점토 포러스콘크리트 조성물"을 제조하는 데 있다.An object of the present invention is an alkaline stimulant (NaOH, NaCl, CaCl 2 , KOH, Ca (OH) 2 , CaSO 4 , Sodium Silicate) to promote weak magnetic hardening of blast furnace slag and blast furnace slag which are industrial by-products in natural clay. Is a continuous pore cured body in which the clay paste formed by mixing with water is mixed with coarse aggregate after mixing with a single or mixed mixture.The aggregates are adhered to each other to make the composition porous and secure the necessary voids and predetermined strength without using cement at all. It is to prepare an "environmentally friendly clay porous concrete composition" that can be adjusted by using the color.

본 발명의 다른 목적은 본래의 포러스콘크리트의 기능은 유지하면서 시멘트를 전혀 사용하지 않고 대체 재료를 사용함으로서 필요한 에너지량이나 지구환경에 주는 부하가 적은 환경친화적인 재료로서 기능을 강화시키는 "환경친화형 점토 포러스콘크리트 조성물" 제공하는 것이다.Another object of the present invention is to "environmentally friendly" to enhance the function as an environmentally friendly material with less energy required or load on the global environment by using an alternative material without using cement at all while maintaining the function of the original porous concrete. Clay porous concrete composition ".

본 발명인 환경친화적인 점토 포러스콘크리트 조성물은 천연상태의 점토에 산업부산물인 고로슬래그와 고로슬래그의 약한 자경성을 촉진시키기 위한 알칼리성 자극제(NaOH, NaCl, CaCl2, KOH, Ca(OH)2, CaSO4, 규산소다)를 단일 혹은 혼용첨가한 후 물로 비벼 형성되어진 점토 페이스트를 굵은 골재에 둘러쌈으로서 골재를 서로접착시킨 다공질의 연속공극 경화체로 구성된다.Environmentally friendly clay porous concrete composition of the present invention is an alkaline stimulant (NaOH, NaCl, CaCl 2 , KOH, Ca (OH) 2 , CaSO to promote the weak hardening of blast furnace slag and blast furnace slag as an industrial by-product in natural clay) 4 ) Sodium silicate) is composed of a porous continuous porous cured body in which aggregates are bonded to each other by enclosing the clay paste formed by mixing water with a single or mixed mixture in a thick aggregate.

상기 조성물에 사용되는 재료에 대해서 설명하면, 아래와 같다.The material used for the said composition is as follows.

상기 점토는 제1차 점토 및 제2차 점토, 마사토 및 진흙 등과 같은 일반적 개념의 모든 흙을 지칭하며, 상기 여러 종류의 흙을 임의로 섞은 것도 포함된다.The clay refers to all soils of a general concept such as primary clays and secondary clays, masatos and muds, and also includes arbitrary mixing of the various kinds of soils.

상기 고로슬래그는 산업부산물로서, 수냉에 의해 제조된 슬래그이면 모두 포함된다.The blast furnace slag is an industrial by-product and includes all slag produced by water cooling.

상기 골재는 쇄석골재, 강자갈, 석산골재, 인공경량골재 등을 포함한 적정 골재크기와 강도를 가진 골재는 모두 포함한다.The aggregate includes all aggregates having a suitable aggregate size and strength, including crushed aggregate, strong gravel, stone aggregate, artificial lightweight aggregate, and the like.

본 발명에 적용한 점토 포러스콘크리트 조성물의 구성 및 용적비는 다음과 같다.The composition and volume ratio of the clay porous concrete composition applied to this invention are as follows.

즉, 본 발명의 점토 포러스콘크리트 배합비를 설명하면, 굵은골재(천연골재 및 재생골재, 경량골재 등의 모든골재를 포함함)는 전체 용적의 48∼72%를 차지하며, 공극량(전공극으로 독립공극과 연속공극을 포함)은 전체 용적의 5∼35%, 점토와 고로슬래그 및 자극제는 전체 용적의 9∼21% 이며, 단위수량은 전체 용적의 4∼9%를 차지하는 배합이다. [도.1 참조]In other words, when explaining the mixing ratio of clay porous concrete of the present invention, the coarse aggregate (including all aggregates such as natural aggregate and recycled aggregate, lightweight aggregate, etc.) occupies 48 to 72% of the total volume, and the amount of voids (independently as pores) Voids and continuous voids) are 5 to 35% of the total volume, clay and blast furnace slag and stimulant are 9 to 21% of the total volume and the unit quantity is 4 to 9% of the total volume. [See Fig. 1]

상기 점토 포러스콘크리트는 시멘트를 전혀 사용하지 않고 기존의 포러스콘크리트와 동일한 기능을 유지하기 위해서는 다공성의 연속 또는 독립된 공극구조의공존과 더불어 소정의 강도를 지니도록 하는 것은 무엇보다 중요하다.In order to maintain the same function as the conventional porous concrete without using cement at all, it is important that the clay porous concrete have a predetermined strength together with the coexistence of porous continuous or independent pore structures.

이와 같은 점토 포러스콘크리트 조성물의 중요 요소인 공극율과 강도는 서로 상관관계를 지니고 있는 것으로 공극율이 높으면 강도는 떨어지고, 공극율을 낮추면 강도는 증가하나 공극의 확보가 어렵게 되어 포러스콘크리트로서 기능을 상실하게 되며 이런 공극구조는 조성물의 강도 및 투수성과 같은 물리적 특성 뿐만 아니라 해양생물의 부착, 수질정화 및 식생에 관한 효과를 좌우한다.The porosity and the strength, which are important factors of the clay porous concrete composition, are correlated with each other. When the porosity is high, the strength decreases, and when the porosity is decreased, the strength increases, but it becomes difficult to secure the voids and thus loses its function as porous concrete The pore structure depends on physical properties such as strength and permeability of the composition, as well as effects on marine organism adhesion, water purification, and vegetation.

즉, 점토 포러스콘크리트 조성물은 천연상태의 점토와 산업부산물인 고로슬래그에 알칼리성 자극제를 첨가, 혼합하여 자극제에 의해 고로슬래그의 자경성을 촉진시키고 잠재수경성과 포졸란 반응을 진행 시켜 시멘트페이스트와 동일한 부착강도를 발현하는 점토페이스트를 제조하여 필요한 공극율과 강도를 확보하는 연속공극 경화체를 제조할 수 있다.In other words, the clay porous concrete composition adds and mixes alkaline stimulants to blast furnace slag, which is a natural clay and industrial by-products, and promotes the hardening of blast furnace slag by stimulating agent, and proceeds the latent hydrophobicity and pozzolanic reaction. By preparing a clay paste expressing the can be prepared a continuous pore cured body to secure the required porosity and strength.

본 발명은 시멘트를 전혀 사용하지 않고 점토 페이스트를 이용하여 필요한 공극율과 강도를 확보할 수 있는 환경친화적인 점토 포러스콘크리트 조성물로서 다음과 같은 효과가 있다.The present invention has the following effects as an environmentally friendly clay porous concrete composition that can secure the necessary porosity and strength using a clay paste without using cement at all.

첫째로, 시멘트를 전혀 첨가하지 않고, 매장량이 풍부한 점토(흙)와 산업부산물인 고로슬래그를 사용하기 때문에 시멘트 생산에 필요한 에너지량의 저감과 산업부산물의 활용에 따른 지구환경에 주는 환경부하를 줄일 수 있다.First, since no clay is added and clay is rich in reserves and blast furnace slag, which is an industrial by-product, the amount of energy required for cement production and the environmental load on the global environment due to the use of industrial by-products are reduced. Can be.

둘째로, 천연의 점토는 친환경적인 색상 및 자연스러운 색감을 구현할 수 있어 다양한 색상의 적용 및 조절이 가능하다.Secondly, natural clay can realize eco-friendly colors and natural colors, and various colors can be applied and adjusted.

셋째로, 조성물이 가지고 있는 다공성과 소정의 강도는 다양한 용도로 활용이 전망되며, 결합재인 점토페이스트는 기존의 시멘트 페이스트 보다 친환경적인 재료로서 수요의 확대가 기대된다.Third, the porosity and predetermined strength of the composition is expected to be utilized for various purposes, and the clay paste, which is a binder, is expected to expand demand as an environment-friendly material than conventional cement paste.

넷째로, 유리석회의 용출에 의한 환경오염을 억제할 수 있다. 즉, 시멘트를 사용한 포러스콘크리트는 수중에서 유리석회의 용출이 현저하며, 특히 초기에 있어서는 동식물에 악영향을 주고 있다. 그러나, 본 발명조성물을 고로슬래그를 이용하여 포졸란 반응 및 잠재수경성 반응을 일으켜 유리석회의 용출을 극소화하여 결점을 개선할 수 있다.Fourthly, environmental pollution by elution of the free lime can be suppressed. That is, the porous concrete using cement is remarkable in the dissolution of free lime in water, and particularly adversely affects the flora and fauna in the early stage. However, the composition of the present invention can be improved by using the blast furnace slag to cause pozzolanic reaction and latent hydraulic reaction to minimize the dissolution of glass lime.
