Description

환경친화형 다공성 식생 콘크리트 조성물{Environment-friendly ecological porous concrete composition for sustainable}Environment-friendly ecological porous concrete composition for sustainable

본 발명은 하천 및 해안의 호안이나 도로의 법면 등을 안정시키기 위해 구축되는 콘크리트 호안블록이나 식생블록 등의 구조물을 제조하는데 사용되는 다공성 콘크리트 조성물에 관한 것으로, 더 상세하게는 콘크리트 조성물에 알카리 양이온 흡착제와 식물성장촉진제를 첨가해 다공질의 구조물을 제조하여 다공성에 의해 배수가 용이하게 이루어지도록 하고, 설치된 경량 기포 콘크리트 구조물 하부의 토양수분을 콘크리트 구조물 표면에 일정량 공급하게 함으로서 식물의 성장이 용이하게 함은 물론 성장된 식물과 하부토양과 다공성 콘크리트 구조물이 일체화를 이뤄 구조물의 파괴 및 유실을 방지하는 기능을 제공하는 환경친화형 다공성 콘크리트 조성물에 관한 것이다.The present invention relates to a porous concrete composition used to manufacture structures such as concrete revetment blocks or vegetation blocks, which are constructed to stabilize river and lake shores and road surfaces, and more particularly, alkali cationic adsorbents in concrete compositions. By adding a plant growth promoter and a porous structure to facilitate drainage by porosity, and by supplying a certain amount of soil moisture under the installed lightweight foam concrete structure to the surface of the concrete structure, Of course, the present invention relates to an environmentally friendly porous concrete composition that provides a function of preventing the destruction and loss of the structure by integrating the grown plant, the underlying soil and the porous concrete structure.

일반적으로 식생을 위한 다공성 콘크리트 조성물은 단순히 다공성에 의한 배수만을 목적으로 하는 것이 아니라, 타설된 콘크리트 구조물의 하부에 존재하는 토양으로부터 수분을 공급받아 콘크리트 구조물 표면에 적당한 수분을 공급하여야 하는 기능을 갖추어야 되므로 최근까지는 콘크리트 조성물의 공극형성에 관한 연구가 주로 이루어졌으며, 종래에는 다공성 콘크리트 조성물을 제조하기 위하여 입도 조절된 골재를 사용하거나, 일본 공개특허 2000-178057호의 식생 콘크리트 제조방법에서와 같이 벤토나이트 골재를 사용하여 벤토나이트의 흡수 팽윤에 의한 다공질 콘크리트 조성물을 제조하거나, 기포제 또는 발포제를 첨가하여 다공성 콘크리트 조성물을 제조하였다. In general, the porous concrete composition for vegetation is not only intended for drainage by porosity, but also has to function to supply adequate moisture to the surface of the concrete structure by receiving water from soil existing under the poured concrete structure. Until recently, studies on the pore formation of concrete compositions have been mainly conducted, and conventionally, particle size controlled aggregates are used to prepare porous concrete compositions, or bentonite aggregates are used as in the vegetation method of Japanese Patent Laid-Open Publication No. 2000-178057. To prepare a porous concrete composition by absorption swelling of bentonite, or a porous concrete composition was prepared by adding a foaming agent or a blowing agent.

그러나, 이와 같이 제조된 다공질 콘크리트 조성물은 결합제로 사용되는 시멘트에 함유되어 있는 산화칼슘(CaO)이 물과 수화 반응하여 수산화칼슘(Ca(OH)2)을 생성하기 때문에 식생 콘크리트를 통하여 식물의 뿌리에 공급되는 수분은 알칼리성을 띄게 되며, 보통의 경우 pH가 12 ~ 13 정도의 강알칼리성을 나타내어 식물이 잘 자라지 못하거나 생장에 장애를 일으키는 문제점이 있었다.However, the porous concrete composition prepared in this way, since calcium oxide (CaO) contained in the cement used as a binder is hydrated with water to produce calcium hydroxide (Ca (OH) 2 ), the vegetation concrete is applied to the root of the plant. The water supplied is alkaline, and in general, the pH is about 12 to 13 strong alkalinity, the plant did not grow well or had a problem causing growth failure.

이러한 강알칼리 성분의 발생을 억제하기 위해 일본 공개특허 평 10-000025호의 식생콘크리트의 중화처리방법에서는 타설 시공한 식생콘크리트에 드라이아이스를 투입하여 드라이아이스가 승화하면서 살수하는 물에 이산화탄소가 용해되어 탄산수가 생성되고 이 탄산수에 의해서 다공성 식생콘크리트가 급속히 중화처리 되어 식물 생육을 조절하는 방법이 개시되었으나, 이 방법은 콘크리트 자체의 중화로 인하여 알칼리 성분이 적게 용출되는 장점이 있으나, 콘크리트가 외부의 인위적 방법에 의해 알칼리가 제거되거나 화학반응에 의해 중성화가 되면서 콘크리트 자체의 강도가 저하되는 문제점이 있다.In order to suppress the generation of such strong alkali components, in the neutralization method of vegetation concrete of Japanese Patent Application Laid-Open No. 10-000025, dry ice is added to the vegetated concrete that is poured, and carbon dioxide is dissolved in the water sprayed by the dry ice. Although a method of controlling plant growth by generating a neutralized porous vegetation concrete by the carbonated water is disclosed, this method has the advantage that less alkali component is eluted due to the neutralization of concrete itself. As the alkali is removed or neutralized by the chemical reaction, there is a problem that the strength of the concrete itself is lowered.

또한, 일본 공개특허 2001-10875호의 다공질 콘크리트 및 그 제조방법에서는 제조원가 절감 및 알칼리성 저하를 위해 고로슬래그 미분말(6000~10000㎠/g)이나 플라이 애쉬를 시멘트 중량에 대하여 20~60중량%를 혼합하여 제조하였으나, 이 방법 역시 강도저하 및 다공성 콘크리트의 재질 특성상 기공부분에 함유된 수분이 겨울철 동결시 체적 팽창을 하면서 콘크리트에 압력을 가하게 되고 계속적으로 이러한 동결 융해과정이 반복되면서 콘크리트가 쉽게 파손되어 기능을 상실함으로써 일반 콘크리트의 수명인 30 ~ 50년 보다 휠씬 적은 3 ~ 5년 정도로 그 수명이 단축되는 문제점이 있었다. In addition, in the porous concrete of Japanese Patent Laid-Open No. 2001-10875 and a method for manufacturing the same, 20 to 60% by weight of blast furnace slag fine powder (6000 to 10000 cm 2 / g) or fly ash is mixed with the cement weight in order to reduce manufacturing cost and reduce alkalinity. However, this method also reduces the strength and material properties of the porous concrete, and the water contained in the pores expands in volume during freezing in winter, exerting pressure on the concrete. As a result of the loss, the service life is shortened to about 3 to 5 years, which is much smaller than that of general concrete, which is 30 to 50 years.

한편, 한국 특허 등록 제 10-300302호의 식물의 생육이 가능한 콘크리트블록에서는 조골재와 시멘트, 물, 혼화제만을 사용하여 제조한 다공성 콘크리트 블록에 식물생장 조절물질과 양분 및 항균제가 포함된 한천 용액을 충진시켜 제조하는 방법이 개시되었으나, 초기에 식물의 발아 및 착생에는 유용한 방법으로 사용되나 콘크리트 제조시 한천 용액 및 항균제 등의 혼합으로 다공성 콘크리트의 강도저하 및 동결융해에 의한 저항성이 저하되는 문제점이 있었다.       Meanwhile, in the concrete block capable of growing plants according to Korean Patent Registration No. 10-300302, the agar solution containing plant growth regulators, nutrients, and antimicrobial agents is filled in porous concrete blocks manufactured using only aggregate, cement, water, and admixture. Although a method of manufacturing has been disclosed, it is initially used as a useful method for germination and growth of plants, but there is a problem in that the resistance of the porous concrete is reduced by the strength reduction and freeze-thawing by mixing agar solution and antimicrobial agent.

본 발명의 환경친화형 다공성 식생 콘크리트 조성물은, Environmentally friendly porous vegetation concrete composition of the present invention,

하천 및 해안의 호안이나 도로의 법면을 안정시키기 위한 호안블록이나 식생블록을 제조하는 다공성 식생 콘크리트 조성물에 있어서, 조성물 전체 부피에 대해 식물성 기포제에 의해 발포된 기포량 30 내지 70 부피%, 비중이 3.15인 일반 시멘트 10 내지 20 부피%, 시멘트 수화를 위한 물 13 내지 20 부피%, 알칼리 성분의 용출을 차단시키기 위한 알칼리 양이온 흡착제 8 내지 20 부피 %로 이루어진다.In a porous vegetation concrete composition for preparing a lake block or vegetation block for stabilizing the surface of rivers and shores or roads, the total volume of the composition is 30 to 70% by volume of foaming foamed by the vegetable foaming agent, and the specific gravity is 3.15. Phosphorus general cement 10-20% by volume, 13-20% by volume water for cement hydration, 8-20% by volume alkaline cation adsorbent to block the elution of the alkaline component.

상기 조성물에는 식물성장촉진제가 알칼리 양이온 흡착제의 부피에 대해 5 내지 10 부피%가 더 혼합될 수 있고, 동결융해에 대한 저항성을 증진시키기 위한 첨가제인 트리 에탄올 아민(tri ethanol amine)을 전체 혼합부피에 대해 0.01 내지 5 부피%가 더 혼합될 수 있다.In the composition, 5-10% by volume of the plant growth promoter may be mixed with respect to the volume of the alkali cation adsorbent, and tri ethanol amine, which is an additive for improving resistance to freezing and thawing, is added to the entire mixing volume. 0.01 to 5% by volume may be further mixed.

또한, 상기 알칼리 양이온 흡착제는 600℃에서 활성화시킨 하소 규조토, 팽창질석, 제올라이트로 이루어진 군으로부터 일종 또는 이종이상 선택사용된다.In addition, the alkali cation adsorbent is selected from the group consisting of calcined diatomaceous earth, expanded vermiculite, zeolite activated at 600 ° C or more than one kind.

이하, 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail.

본 발명의 경량기포 콘크리트를 구성하는 다공성 기포는 식물성 기포제를 사용하여 형성한다. 기포제는 동물성 기포제와 식물성 기포제로 구분할 수 있으며, 동물성 기포제는 폐쇄 기공의 형성으로 인하여 수분의 이동 등이 식물성 기포제에 의한 기포보다는 원활하지 못하기 때문에 본 발명에는 식물성 기포제를 사용하는 것이 바람직하다. Porous bubbles constituting the lightweight foam concrete of the present invention is formed using a vegetable foaming agent. The foaming agent can be classified into an animal foaming agent and a vegetable foaming agent, and the animal foaming agent is preferably used in the present invention because the movement of moisture is not smoother than the foaming by the vegetable foaming agent due to the formation of closed pores.

본 발명에서는 식물성 기포제를 물과 1:20의 비율로 혼합한 후 3 내지 5 기압의 기포 발생 압력으로 발포하여 생성되는 기포가 40 내지 70 kg/m3의 밀도를 갖게 한다. In the present invention, the air bubbles produced by mixing the vegetable foaming agent with water at a ratio of 1:20 and foaming at a bubble generating pressure of 3 to 5 atm to have a density of 40 to 70 kg / m 3 .

이때 기포의 밀도가 40 kg/m3보다 작게 되면 생성기포가 소포가 쉽게 되어 최종 결과물에서 직경이 큰 기공이 많이 발생하게 되어 전체적인 압축강도 저하를 가져오게 된다. 또한 기포의 밀도가 70 kg/m3 이상이 되면 너무 작은 크기의 기공이 형성되어 배수성능의 저하 또는 경량기포 콘크리트의 동결융해 저항성 등이 낮아지게 된다.At this time, if the bubble density is less than 40 kg / m 3 , the resulting bubbles are easily defoamed, a large number of pores with a large diameter in the final product will result in a decrease in the overall compressive strength. In addition, when the bubble density is 70 kg / m 3 or more, pores of too small size are formed, which lowers drainage performance or freeze-thawing resistance of lightweight foam concrete.

생성된 기포의 혼합량은 부피%를 기준으로 30 내지 70 부피%를 사용하며, 비중이 3.15인 일반 시멘트를 10 내지 20부피%, 시멘트 수화를 위한 물의 량은 13내지 20 부피%, 하소 규조토 또는 팽창질석이나 제올라이트로 이루어진 군으로부터 선택사용한 알칼리 양이온 흡착제 8 내지 20 부피%로 혼합한다. The amount of bubbles produced is 30 to 70% by volume based on volume%, 10 to 20% by volume of ordinary cement having a specific gravity of 3.15, the amount of water for hydration of cement is 13 to 20% by volume, calcined diatomaceous earth or expansion 8-20% by volume of an alkaline cation adsorbent selected from the group consisting of vermiculite and zeolite is mixed.

이때 활성화 규조토는 600℃±50℃에서 하소하면 하니컴 모양의 다공성 재료로 변화하면서 다양한 흡착 기능을 갖게 됨으로 상기 온도로 하소하여 사용한다. 그러나 하소 온도가 550℃보다 낮거나 650℃ 보다 높은 경우 충분히 활성화 되지 못하여 하니컴 구조를 이루지 못하게 됨으로 상기 설정온도로 하소하여야 한다. 하소 규조토 이외에 양이온 흡착기능이 우수한 재료는 팽창질석과 제올라이트를 사용할 수 있으며, 활성화 규조토, 팽창질석 또는 제올라이트는 단독으로 또는 2개 이상의 재료를 혼합하여 사용할 수 있다. At this time, the activated diatomaceous earth is calcined at 600 ℃ ± 50 ℃ is changed to a honeycomb-like porous material and has a variety of adsorption function is used by calcining at the above temperature. However, when the calcination temperature is lower than 550 ℃ or higher than 650 ℃ it can not be sufficiently activated to form a honeycomb structure and should be calcined to the set temperature. In addition to calcined diatomaceous earth, materials having excellent cation adsorption function may use expanded vermiculite and zeolite, and activated diatomaceous earth, expanded vermiculite or zeolite may be used alone or in combination of two or more materials.

다음으로 상기 혼합물에는 휴믹산이나 리그닌 등의 식물성장촉진제를 알칼리 양이온 흡착제 혼합부피에 대해 5 내지 10 부피% 더 혼합할 수 있다.Next, in the mixture, plant growth promoters such as humic acid or lignin may be further mixed in an amount of 5 to 10% by volume with respect to the mixed volume of the alkali cation adsorbent.

상기 식물성장촉진제의 첨가량이 5 부피% 이하인 경우 식생을 위한 충분한 양분을 공급하지 못하게 되며, 10 부피% 이상인 경우 시멘트의 응결 경화를 지연시켜 소요 강도 발현 저하를 가져오게 된다. When the added amount of the plant growth promoter is less than 5% by volume, it is impossible to supply sufficient nutrients for vegetation, and when it is more than 10% by volume, the cement hardening is delayed to bring down the required strength.

또한 이 1차 혼합물 중의 발포된 기포를 제외한 전체 부피에 대하여 장기강도 향상 및 동결융해에 대한 저항성 증진시키기 위해 첨가제인 트리에탄올 아민(tri ethanol amine) 0.01 내지 5 부피%를 첨가 혼합할 수 있다. 상기 트리에탄올 아민이 0.01 부피% 이하인 경우에는 동결융해에 대한 저항성이 부족하게 되며. 첨가량이 5부피% 이상인 경우에는 시멘트 재료의 응결 지연효과로 인하여 강도 저하가 따르게 됨으로 상기 범위 내에서 혼합사용하는 것이 바람직하다. In addition, 0.01 to 5% by volume of triethanol amine, an additive, may be added and mixed in order to improve long-term strength and enhance resistance to freezing and thawing with respect to the entire volume except the foamed bubbles in the primary mixture. When the triethanol amine is less than 0.01% by volume, the resistance to freezing and thawing will be insufficient. When the added amount is 5% by volume or more, it is preferable to use the mixture within the above range because the strength decreases due to the effect of delaying the setting of the cement material.

상기 배합 조건에 의해 혼합된 콘크리트 조성물은 일정한 규격의 형틀에 부 어 28일 동안 습건 양생시키다. 이 때 습건 양생 조건은 온도 섭씨 30도±5도, 습도는 65%에서 80%의 범위로 한다.The concrete composition mixed by the above mixing conditions is poured into a mold of a certain size and wet-cured for 28 days. At this time, the wet curing condition is in the range of 30 degrees ± 5 degrees Celsius, humidity is in the range of 65% to 80%.

이하, 실시예를 통하여 본 발명을 보다 상세하게 설명한다. Hereinafter, the present invention will be described in more detail with reference to Examples.

실시예Example

식물성 기포제를 물과 1:20의 비율로 혼합한 후 기포 발생 압력 3.5 기압의 압력으로 발포시켰다. 이때 생성된 기포의 밀도는 48 kg/m3의 밀도를 나타내었다. The vegetable foaming agent was mixed with water at a ratio of 1:20, and then foamed at a pressure of bubble generation pressure of 3.5 atmospheres. The density of the bubbles produced at this time showed a density of 48 kg / m3.
