In order to increase the strength of concrete and to suppress alkali elution, admixtures such as blast furnace slag and silica fume, which are industrial by-products, were used.The mixture of nitrogen-based and phosphorus-based fertilizers coated with polymer was used to supply nutrients to planted plants.

최근 산업화 및 도시화로 인한 환경오염에 대한 인식이 확산되어 환경보존의 필요성이 대두되고 있다. 사회기반시설인 도로, 철도, 항만, 상수도 등의 토목구조물 및 건축 구조물에 사용되어온 콘크리트는 경제와 문화 발전에 크게 공헌하여 왔다. 그러나 이들 콘크리트는 기능을 추구하는데 그쳐 자연을 파괴하고 동식물의 서식을 방해하여 환경문제에 있어 부정적으로 인식되고 있다. 특히 하천 및 연안수역의 호안블록이나 수중콘크리트 구조물은 육상생태계와 수중생태계의 단절로 인한 생태계의 파괴 및 환경오염을 가속화시키는 원인이 되고 있다. 따라서 기존의 호안블록이나 수중콘크리트 구조물의 기능 및 장점을 유지하고, 생태계에 피해를 주지 않는 기술 및 제품의 개발이 시급한 실정이다.Recently, the awareness of environmental pollution due to industrialization and urbanization has spread, and the necessity of environmental preservation is emerging. Concrete, which has been used for civil and structural structures such as roads, railways, harbors, waterworks, etc., which are infrastructure, has contributed greatly to economic and cultural development. However, these concretes are only negatively regarded as environmental problems by destroying nature and hindering the habitat of animals and plants. In particular, shore blocks and aquatic concrete structures in rivers and coastal waters are responsible for accelerating the destruction of ecosystems and environmental pollution due to the disconnection of terrestrial and aquatic ecosystems. Therefore, it is urgent to develop technologies and products that maintain the functions and advantages of existing shore blocks or underwater concrete structures and do not damage the ecosystem.
본 발명은 하천호안 및 연안수역의 환경오염과 생태계 피해를 감소시키기 위하여 각종 혼화재 및 수지 처리된 질소계, 인계의 비료를 연속공극이 형성된 포러스콘크리트에 혼입하여 착상 식물에 원활한 영양분을 공급하여 식생기반 및 조기생장을 촉진시키고, 식물연쇄에 의한 환경복원 효과를 높이는 수지처리 입상비료를 이용한 고기능 식생용 포러스콘크리트의 제조개발을 목적으로 한 것이다.In order to reduce environmental pollution and ecosystem damage in riverside shores and coastal waters, various admixtures, resin-treated nitrogen-based and phosphorus-based fertilizers are mixed in porous pores with continuous pores to supply nutrients to planting plants. And it aims at the development and development of high functional vegetal forage concrete using resin-treated granular fertilizer that promotes early growth and enhances the environmental restoration effect by the plant chain.

Granular fertilizer is nitrogen-based fertilizer with 45-47% nitrogen content, 0.4-0.6% water, 0.9-1.1% Biuret, 15-17% soluble phosphoric acid, 23-26% lime, 15-17% silicic acid fertilizer. 0.7 ~ 3.0mm was used, and the polymer used for the resin treatment of granular fertilizer was a mixed resin of vinyl acetate and polymerized resin emulsion having a viscosity of 40,000 to 60,000 as the primary coating agent and 43 to 47% of the active content. As a coating agent, a special acrylic resin having a solid content of 70% and a viscosity of 50,000 to 100,000 that can control hydrophilicity and hardness was used.
본 발명에서 사용된 배합은 고기능 식생용 포러스콘크리트의 품질특성에 가장 큰 영향을 미치는 공극률을 20∼30%로 변화시키면서 이에 대해 산업부산물인 고로슬래그 및 실리카흄 등의 혼화재를 사용하였고, 혼입률은 시멘트 중량비로 각각 30∼60%, 5∼20%로 혼입하였으며, 시멘트의 분산작용에 의해 콘크리트의 성질을 개선시키는 혼화제로서 고능성 AE감수제를 시멘트 중량비로 1∼3%로 혼입하였다.In the formulation used in the present invention, the porosity which has the greatest effect on the quality characteristics of the high functional vegetal concrete was changed to 20 to 30%, and the admixtures such as blast furnace slag and silica fume, which are industrial by-products, were used. 30 to 60% and 5 to 20%, respectively, and a high performance AE reducing agent was mixed at a cement weight ratio of 1 to 3% as a admixture to improve the properties of concrete by dispersing the cement.
또한 포러스콘크리트에 식물의 착상을 원활하게 하기 위하여 입상비료를 수지처리하여 시멘트 중량비로 5∼20% 혼입하였다.In addition, the granular fertilizer was resin-treated and mixed in 5 to 20% by weight of cement in order to facilitate planting in the porous concrete.

본 발명에서는 수지처리 입상비료를 이용한 고기능 식생용 포러스콘크리트의 품질특성을 파악하기 위하여 다음과 같은 실험을 수행하였다. 수지처리된 입상비료의 침지수 차이에 따른 용해율을 파악하기 위하여 증류수와 해수 100㎖에 입상비료를 각각 3g의 비율로 넣고 60, 120, 180일에 용해율을 측정하였다. 공시체 제작에 따른 수지처리 입상비료의 파괴율을 측정하기 위하여, 비료 및 골재만으로 혼합하는 방법(A방법)과 시멘트페이스트에 미리 혼입한후 골재와 혼합하는 방법(B방법)으로 나누어 실험하였으며, 혼합시간을 3분으로 하고 1분마다 일정량의 시료를 채취하여 중량에 의한 파괴율을 측정하였다. 또한 수지처리된 입상비료를 이용한 포러스콘크리트의 비료성분 용출량 시험은 φ15×30cm의 공시체를 제작하여 해수에 30일, 90일 침지한후 공시체를 꺼낸후, 7리터의 활성탄 처리를한 수돗물에 넣고 일정기간후 공시체로부터 용출되는 질소계의 암모니아 농도 및 인계의 인산농도를 1㎖까지 측정하였으며, pH도 같이 측정하였다. 압축강도시험방법은 φ15×30cm 원주형 공시체를 제작하여 KS F 2408『콘크리트의 압축강도 시험방법』에 준하여 실험하였다. 또한 수지처리 입상비료를 이용한 포러스콘크리트의 육상식물에 대한 식생 능력을 평가하기 위하여 공시체(40×40×10cm)를 제작하여 이에 보수재 및 배양토등을 혼합한 충진재를 내부공극에 충진하고, 3cm가량의 복토를 실시하여 씨앗을 파종하였으며, 파종후 재령 및 비료의 혼입 여부에 따른 생육상태를 관측하여 식생능력을 평가하였다. 수지처리 입상비료를 이용한 포러스콘크리트의 수중식물 및 생물에 대한 부착 및 식생능력을 평가하기 위하여 공시체(40×40×10cm)를 제작하여 자연 해수에 침지하고, 침지후 4개월후에 꺼내서 공시체에 부착된 조류 및 생물의 부착 및 생육상태를 육안으로 관찰하였다.In the present invention, the following experiments were carried out to grasp the quality characteristics of the high-performance vegetation forged concrete using resin-treated granular fertilizer. In order to determine the dissolution rate according to the difference in the immersion water of the resin-treated granular fertilizer, the granular fertilizer was added to 100 ml of distilled water and seawater at a ratio of 3 g, and the dissolution rate was measured at 60, 120, and 180 days. In order to measure the destruction rate of the granulated fertilizer of resin treatment according to the specimen preparation, the experiment was divided into the method of mixing only with fertilizer and aggregate (A method) and the method of mixing with aggregate and mixing with aggregate (B method) in advance. The time was set to 3 minutes, and a certain amount of samples were taken every minute to measure the breakage rate by weight. In addition, the fertilizer component elution test of the porous concrete using resin-treated granular fertilizer was prepared by φ15 × 30cm specimens, soaked in seawater for 30 days and 90 days, and then taken out of the specimens and placed in 7 liters of activated carbon treated tap water. After a period of time, the nitrogen-based ammonia and phosphorus-phosphate concentrations eluted from the specimens were measured up to 1 ml and the pH was also measured. The compressive strength test method was made in accordance with KS F 2408, `` Compressive strength test method for concrete '', with a φ15 × 30cm cylindrical specimen. In addition, to evaluate the vegetation capacity of terrestrial plants of pore concrete using resin-treated granular fertilizer, a specimen (40 × 40 × 10 cm) was produced, and the fillers mixed with water-retaining materials and cultured soil were filled in the internal voids, and about 3 cm Seeds were sown by covering soil, and the vegetation capacity was evaluated by observing the growth status according to the age and fertilizer mix after sowing. In order to evaluate adhesion and vegetation ability of aquatic plants and organisms of porous concrete using resin-treated granular fertilizer, a specimen (40 × 40 × 10cm) was prepared and immersed in natural sea water, and after 4 months of immersion, it was removed and attached to the specimen. The attachment and growth of algae and organisms was visually observed.

다음 표 2는 수지처리 입상비료의 용해율을 파악하기 위하여 증류수 및 해수 100㎖당 입상비료를 3g의 비율로 넣고, 침지후 60일, 120일, 180일에 대하여 용해율을 측정한 것이다.The following Table 2 is to determine the dissolution rate of the resin-treated granular fertilizer in the ratio of 3g of granular fertilizer per 100ml of distilled water and seawater, and measured the dissolution rate for 60 days, 120 days, 180 days after immersion.
수지처리 입상비료의 용해율 시험결과는 증류수의 경우가 해수의 경우보다 60일, 120일에서는 용해율이 높은 것으로 나타났으나 180일에서는 용해율의 차이가 미비하였다. 이러한 경향은 해수중에는 각종 염류가 녹아있기 때문에 짧은 기간에서는 입상비료의 코팅제로 쓰인 각종 수지성분과 염류사이의 화학반응에 의한 것이다.The dissolution rate test results of the resin-treated granular fertilizer showed that the dissolution rate of distilled water was higher in 60 days and 120 days than in the case of sea water, but the difference in dissolution rate was insufficient at 180 days. This tendency is due to the chemical reaction between the various resin components and salts used as coatings for granular fertilizers in the short term because various salts are dissolved in seawater.
다음의 표 3은 수지처리된 입상비료의 혼합방법 및 혼합시간에 따른 파괴율을 측정한 시험결과이다.Table 3 below is a test result of measuring the destruction rate according to the mixing method and mixing time of the resin-treated granular fertilizer.

(주2) 비료를 시멘트페이스트에 미리 혼입한 후 골재와 혼합하는 방법(Note 2) Mixing fertilizer with cement paste and mixing with aggregate
수지처리 입상비료의 혼합방법에 따른 파괴율 시험결과를 고찰하여 보면, 혼합시간이 증가함에 따라 파괴율은 증가하였으며 A방법에서는 질소계 비료가 인계 비료에 비하여 파괴율이 컸으며, B방법에서는 비료 차이에 따른 파괴율의 차이는 미비하였다. 종합적으로 B방법이 A방법에 비하여 파괴율이 작았으며, 이러한 경향은 유동성을 부여한 B방법이 유효했던 것으로 판단된다.According to the results of the mixing rate test of the resin-treated granular fertilizer, the destruction rate increased with increasing mixing time. In the method A, the nitrogen-based fertilizer was higher than the phosphorus-based fertilizer. The difference of the failure rate according to the difference was insignificant. Overall, the method B had a lower breakdown rate than the method A, and this tendency seems to be valid for the method B with fluidity.
다음의 표 4는 해수에 침지한 수지처리 입상비료를 이용한 포러스콘크리트의 비료성분 용출량을 측정한 시험결과이다.Table 4 below is a test result of measuring the fertilizer component elution amount of the porous concrete using the resin-treated granular fertilizer immersed in seawater.
수지처리 입상비료를 이용한 포러스콘크리트를 해수에 침지시 비료의 용출량 시험결과를 고찰하여 보면, 비료를 혼입하지 않았을 경우 암모니아 용출량은 0.1∼0.2㎖, 인산용출량은 0.01∼0.02㎖로 나타나 극히 작은 것으로 나타났으며, 비료를 혼입한 경우에서는 암모니아 용출량은 9.4∼80.1㎖, 인산용출량은 0.10∼0.18㎖로 나타나 혼입하지 않았을 경우에 비하여 상당히 크게 나타났다. 따라서 수지처리 입상비료를 포러스콘크리트에 혼입하면 착상된 식물에 원활한 영양분 공급에 유효할 것으로 판단된다. 또한 혼화재 혼입률 및 종류에 따른 비료 성분의 용출량의 차이는 미비한 것으로 나타났다. 또한 침적일수가 경과함에 따라 비료성분이 점차적으로 용출되는 것을 확인할 수 있었다.When the ferrous concrete using resin-treated granular fertilizer was immersed in seawater, the dissolution test result of fertilizer was found to be 0.1 ~ 0.2ml and phosphoric acid dissolution rate was 0.01 ~ 0.02ml without fertilizer. In the case of fertilizer incorporation, the ammonia elution amount was 9.4-80.1mL and the phosphoric acid elution amount was 0.10 ~ 0.18mL, which was considerably larger than in the case of no fertilization. Therefore, when granulated resin-treated fertilizer is added to the porous concrete, it is considered to be effective for supplying nutrients to the planted plant. In addition, the difference in the dissolution amount of the fertilizer components according to the admixture content and type of admixture was found to be insignificant. In addition, it was confirmed that the fertilizer component is gradually eluted as the days of immersion.
다음의 표 5는 해수에 침지한 수지처리 입상비료를 이용한 포러스콘크리트의 알칼리 용출량(pH)을 측정한 시험결과이다.Table 5 below is a test result of measuring alkali elution (pH) of porous concrete using resin-treated granular fertilizer immersed in seawater.
해수에 침지한 포러스콘크리트의 알칼리 용출량(pH) 결과를 고찰하여 보면, 침적일수가 증가함에 따라 알칼리 용출량은 감소하는 경향을 나타냈다. 이러한 경향은 시간이 경과함에 따라 해수중에 녹아있는 CO2에 의하여 공시체가 중성화됨에 따라 알칼리 용출량(pH)이 감소한 것으로 판단된다. 또한 혼화재의 혼입량이 증가함에 따라 알칼리 용출량(pH)은 감소하였으며, 이러한 경향은 혼화재가 유리석회와 포졸란 반응을 일으키고, 내부 미세공극이 치밀해져 유리석회의 용출을 억제시켰기 때문으로 판단된다. 따라서 적정량의 혼화재 사용은 포러스콘크리트의 중성화를 촉진시켜 식물 및 생물의 생육에 유효할 것으로 판단된다.As a result of examining the alkali elution amount (pH) of the porous concrete immersed in seawater, the alkali elution amount tended to decrease as the number of deposition days increased. This trend seems to be due to the decrease in alkali elution (pH) as the specimen is neutralized by CO 2 dissolved in sea water over time. Also, as the amount of admixture increased, the alkali elution amount (pH) decreased, which is believed to be due to the admixture causing glass lime and pozzolanic reactions and the internal micropores to be dense, thereby inhibiting dissolution of glass lime. Therefore, the use of an appropriate amount of admixture is expected to be effective for the growth of plants and organisms by promoting the neutralization of the porous concrete.
다음의 표 6은 재령 28일에서 수지처리 입상비료를 이용한 포러스콘크리트의 압축강도 시험결과이다.Table 6 below shows the compressive strength test results of the porous concrete using resin granulated fertilizer at 28 days of age.
압축강도 시험결과를 고찰하여 보면 5∼10mm의 쇄석을 사용한 경우에는 178∼ 225 kg/cm2, 10∼20mm의 쇄석을 사용한 경우에는 140∼168kgf/cm2의 강도를 발현하였다. 또한 혼화재 사용에 따른 강도특성은 골재 크기에 상관없이 실리카흄 10%에서 가장 큰 압축강도를 나타냈으며, 혼화재를 사용하지 않은 경우에 비하여 18∼20%의 강도증진을 나타냈다. 이는 실리카흄을 혼입함에 따라 포졸란 반응 및 콘크리트 내부의 미세공극이 충진되어 공시체가 밀실해져 강도가 증진된 것으로 판단된다.The results of compressive strength test showed that 178-225 kg / cm 2 when 5-10 mm crushed stone was used and 140-168 kgf / cm 2 when 10-20 mm crushed stone was used. In addition, the strength characteristics according to the use of admixtures showed the greatest compressive strength at 10% of silica fume regardless of the aggregate size. As the silica fume is mixed, the pozzolanic reaction and the fine pores inside the concrete are filled, and thus the specimen is closed and the strength is improved.
다음의 표 7은 수지처리 입상비료를 혼입한 포러스콘크리트의 육상식물에 대한 식생능력을 평가하기 위하여 재령별 초장의 생육상태를 측정한 결과이다.Table 7 below shows the results of measuring the growth status of grass height by age to evaluate the vegetation capacity of terrestrial plants mixed with resin-treated granular fertilizer.
식생능력 측정결과를 고찰하여 보면, 골재입도가 5∼10mm의 경우 비료를 혼입한 것이 비료를 혼입하지 않은것에 비하여 초장이 3.1∼4.9cm 더 컸으며, 10∼20mm의 경우에서는 비료를 혼입한 것이 혼입하지 않은것에 비하여 초장이 1.5∼3.6cm 더 크게 나타나, 골재 크기에 관계없이 비료를 혼입한 경우가 식생능력이 향상되는 것으로 나타났다.The results of the measurement of vegetation capacity showed that when the aggregate particle size was 5 ~ 10mm, the fertilizer was mixed with 3.1 ~ 4.9cm longer than the fertilizer, and the fertilizer was mixed when 10 ~ 20mm. The height of the shoots was 1.5 ~ 3.6cm larger than that of no mixing, and the fermentation of fertilizer was improved regardless of the aggregate size.

수지처리 입상비료를 혼입한 포러스콘크리트Porous concrete with resin-treated granular fertilizer
사진 1은 수지처리 입상비료를 혼입하지 않은 포러스공시체의 사진이며, 사진2는 수지처리 입상비료를 혼입한 포러스공시체의 사진이다. 이를 관찰하여보면 비료를 혼입했을 경우가 조류의 부착 및 생육이 양호하였다. 따라서 수지처리 입상비료를혼입한 포러스콘크리트는 환경오염에 의한 생태계 파괴지역의 조기 환경복원에 유효할것으로 판단된다.Photograph 1 is a photograph of the porous specimen not mixed with resinous granular fertilizer, and photograph 2 is a photograph of the porous specimen mixed with resinous granular fertilizer. Observation of this resulted in good fertilization and growth of algae. Therefore, porous concrete mixed with resin-treated granular fertilizer is expected to be effective for the early restoration of environmentally damaged areas due to environmental pollution.
상술한 바와 같이 본 발명은 수지처리 입상비료를 이용한 포러스콘크리트를 하천호안 및 연안수역의 수중구조물 및 호안블록등에 적용함으로써 환경오염의 방지는 물론 생태계 피해지역에 식물의 조기 생장과 식생기반을 확보하여 식물연쇄에 의한 환경복원 효과가 있는 것이다.As described above, the present invention is applied to the porous concrete using resin-treated granular fertilizer to the underwater structures and shore blocks of river shores and coastal waters to prevent environmental pollution as well as to secure early growth and vegetation base of plants in ecosystem damage areas. There is an environmental restoration effect by the plant chain.
