Organic rice husks are prone to spoilage due to invisible microorganisms, humidity, temperature, and proper nutrients, and thus have limitations in long storage after harvest. Therefore, in order to use chaff as a construction material, it is necessary to overcome the limitation of storage and use due to the lack of durability and corruption.

Although a method of coating an antibacterial agent on the surface of the resin coating layer of the fiber has been suggested to prevent spoilage of the chaff, it is not a technology for a block that takes compressive strength, and it is not easy to laminate the resin coating layer and the antibacterial agent coating layer on the fiber, and the chaff itself Corruption that occurs during the storage of raw materials cannot be prevented.

이하에서는 시험예들과 함께 본 발명을 상세히 설명하기로 한다.Hereinafter, the present invention will be described in detail together with test examples.
본 발명에서는 소석회를 이용하여 왕겨의 부패 저항성능을 확보하고, 잠재수경성 재료의 한 종류인 고로슬래그 미분말의 수화반응을 촉진시키도록 하였다. In the present invention, by using slaked lime to secure the decay resistance performance of chaff, and to promote the hydration reaction of the fine blast furnace slag, a type of latent hydraulic material.
유기물질인 왕겨는 보이지 않는 미생물, 습도, 온도, 적절한 양분 등으로 부패하기 쉽다. 따라서, 추수 후 오랜 보관에 있어서도 한계를 가지고 있다. 즉, 왕겨는 내구성능 미확보 및 부패문제 등으로 보관 및 이용에 한계가 있으므로 본 발명의 발명자는 이를 극복하고 왕겨를 건설재료로 이용하기 위해 소석회를 이용한 왕겨 처리 방안에 대한 연구 및 실험을 진행하였다.Chaff, an organic material, is susceptible to spoilage by invisible microorganisms, humidity, temperature, and proper nutrients. Therefore, there is a limit to long-term storage after harvest. That is, rice husks have limitations in storage and use due to lack of durability and corruption, so the inventors of the present invention have overcome this and conducted research and experiments on treatment methods for chaff using slaked lime to use rice husks as construction materials.
아래 [표 1]은 왕겨에 소석회를 혼합하고 건비빔한 왕겨 혼합물에 대한 부패 저항성능 실험결과를 정리한 것이다. Table 1 below summarizes the results of experiments on the resistance to decay against chaff mixtures mixed with slaked lime and chaff.
위의 [표 1]은 왕겨에 소석회를 섞어 비빔한(건비빔) 후 실내 상온에 방치하였을 경우 미생물 발생 유무(항곰팡이 성능)를 관찰한 결과이다. 즉, 왕겨의 오랜 저장을 위해 왕겨 1000g에 소석회를 0~300g 범위에서 차등적으로 혼합한 후 재령별로 곰팡이를 비롯한 미생물 발생(부패 발생) 상태를 확인한 결과, 왕겨 1000g에 소석회를 50g 이상(왕겨 대비 5wt% 이상) 첨가할 경우, 장기간의 존치기간 동안 곰팡이 발생이 제어됨을 알 수 있었다.[Table 1] above is the result of observing the presence or absence of microbial activity (anti-mildew performance) when mixed with slaked lime in rice husks and left at room temperature after boiling. That is, for long-term storage of chaff, 1000g of chaff is mixed with slaked lime in the range of 0 to 300g, and then microbial occurrence (decay), including mold, is determined by age, 50g or more of slaked lime to chaff (compared to chaff) 5 wt% or more), it was found that mold generation is controlled during a long period of presence.
한편 고로슬래그는 물과 접한 직후 Ca2+이온이 용출되고 그 표면에 투과성이 나쁜 부정형의 산화피막이 형성되어 이 피막으로 인해 고로슬래그 입자속으로 물의 침투 및 고로슬래그 입자로부터의 이온의 용출이 억제되기 때문에 수화반응은 진행이 어렵다. 그러나 고로슬래그 입자에 OH-가 흡착되면 이 막구조(유리구조)가 파괴되어 SiO2, Al2O3, CaO, MgO의 용출이 촉진되고 반응이 시작되게 되며 일단 반응이 시작되면 고로슬래그는 자체속에서 용출되는 알칼리성분에 의해 높은 pH의 지속이 가능하게 된다. 따라서, 상기 왕겨의 부패를 방지하기 위해 혼합된 소석회(Ca(OH)2)가 고로슬래그 입자에 OH-를 공급하는 알칼리자극제 역할을 할 수 있으며, 고로슬래그의 잠재수경성 반응에 필요한 알칼리자극제의 양은 초기 수화반응을 일으킬 수 있는 정도만 필요(이후의 반응은 고로슬래그속에 함유되어 있는 CaO, SiO₂등의 성분이 용출하여 지속적인 수화반응 진행)하다.Meanwhile, the Ca 2+ ions are eluted immediately after contact with water, and an amorphous oxide film having poor permeability is formed on the surface of the blast furnace slag, thereby preventing the infiltration of water into the blast furnace slag particles and the elution of ions from the blast furnace slag particles. Therefore, the hydration reaction is difficult to proceed. However, when OH - is adsorbed on the blast furnace slag particles, this membrane structure (glass structure) is destroyed, so that the elution of SiO 2 , Al 2 O 3 , CaO, and MgO is promoted and the reaction begins. Once the reaction begins, the blast furnace slag itself It is possible to maintain a high pH due to the alkali component eluting from the inside. Therefore, the slaked lime (Ca(OH) 2 ) mixed to prevent spoilage of the chaff can serve as an alkali stimulator for supplying OH - to blast furnace slag particles, and the amount of alkali stimulator required for latent hydraulic reaction of blast furnace slag is Only the extent that can cause the initial hydration reaction is required (the subsequent reaction proceeds with continuous hydration by elution of components such as CaO and SiO₂ contained in the blast furnace slag).
본 발명은 위와 같은 원리에 기초하여, 고로슬래그 미분말, 석분 및 왕겨에 소석회가 혼합된 왕겨 혼합물을 포함하는 결합재 조성물을 도출하였으며, 이러한 결합재 조성물에 물을 첨가하여 경량블록 조성물을 도출하였다. 본 발명에서 상기 소석회는 왕겨의 부패를 방지하는 기능은 물론 결합재의 주 원료인 고로슬래그 미분말에 대한 알칼리자극제 기능을 겸하는 것이다. The present invention, based on the above principles, derived a binder composition comprising a chaff mixture in which slaked lime is mixed with blast furnace slag fine powder, stone powder, and chaff, and water was added to the binder composition to derive a lightweight block composition. In the present invention, the slaked lime serves as an alkali stimulant function for the fine powder of the blast furnace slag, which is the main raw material of the binder, as well as the function of preventing the decay of chaff.
아래 [표 2]는 상기 경량블록 조성물의 성분 비율에 따른 여러 가지 물성을 시험한 결과를 정리한 것이다. [Table 2] below summarizes the results of testing various physical properties according to the component ratio of the lightweight block composition.
위의 [표 2]는 고로슬래그 미분말 100중량부를 기준으로 석분(골재 포함) 225~375중량부, 왕겨 0~150중량부 및 소석회를 상기 왕겨 대비 0~20wt% 범위에서 차등적으로 혼합 조성한 결합재 조성물에 물 25중량부를 혼합한 시험체들의 압축강도(재령 28일), 물풀림성, 항곰팡이 성능 및 가압성형 가능여부를 시험한 결과를 나타낸 것이다.The above [Table 2] shows that 225 to 375 parts by weight of stone powder (including aggregate), 0 to 150 parts by weight of chaff, and slaked lime based on 100 parts by weight of fine powder of blast furnace slag are mixed in a range of 0 to 20 wt% compared to the chaff. It shows the results of testing the compressive strength (age 28 days), water looseness, anti-mildew performance, and whether press molding is possible for test specimens mixed with 25 parts by weight of water in the composition.
물풀림이 발생하지 않고, 곰팡이가 발생하지 않고, 가압 성형을 할 수 있는 조건이 모두 충족되는 시험체는 고로슬래그 미분말 100중량부; 석분 275~325중량부; 왕겨 50~100중량부 및 상기 왕겨 중량 대비 소석회 5~20wt%를 포함하여 조성된 결합재 조성물에 물이 25중량부 혼합된 것이었다. 위의 [표 2]는 물 혼합량을 고로슬래그 미분말 100중량부 대비 25중량부로 고정시킨 시험체의 시험결과를 나타낸 것이나, 상기 물 혼합량은 상기 고로슬래그 미분말, 석분 및 왕겨 혼합물을 포함하는 결합재 조성물의 중량에 따라 20~30중량부의 범위 내에서 조절 가능하다.No water loosening occurs, mold does not occur, and the test body that satisfies all the conditions that can be press-molded includes 100 parts by weight of the fine powder of the blast furnace slag; 275 to 325 parts by weight of stone powder; Water was mixed with 25 parts by weight of the binder composition comprising 50 to 100 parts by weight of chaff and 5 to 20 wt% of slaked lime to the weight of the chaff. [Table 2] above shows the test results of the test body in which the water mixing amount was fixed at 25 parts by weight compared to 100 parts by weight of the blast furnace slag fine powder, but the water mixing amount is the weight of the binder composition comprising the blast furnace slag fine powder, stone powder, and rice husk mixture It can be adjusted within 20 to 30 parts by weight.
가압 성형 경량블록 적용가능성 측면으로 볼 때, 물을 포함한 경량블록 조성물 전체량 대비 왕겨의 첨가율은 20wt% 이하로 제어하되, 왕겨가 전혀 혼합되지 않은 블록 대비 10wt% 이상의 경량성 확보를 위해서는 상기 경량블록 조성물 전체량 대비 왕겨 첨가율을 10wt% 이상으로 제어해야 한다.In view of the applicability of the pressurized molding light weight block, the addition rate of rice hull compared to the total amount of the light weight block composition including water is controlled to 20 wt% or less, but the light weight block is used to secure light weight of 10 wt% or more compared to a block in which no chaff is mixed at all. The proportion of rice husk added to the total composition should be controlled to 10 wt% or more.
또한, 위의 [표 1], [표 2]에 나타난 시험 결과에서, 소석회는 왕겨 대비 5wt% 이상을 첨가할 때 물풀림 저항성과 항곰팡이 성능이 함께 발현됨을 알 수 있다. 다만, 상기 소석회가 왕겨 대비 20wt% 이상 첨가될 때에는 재령별 압축강도 증진 효과도 크지 않으므로 상기 소석회 첨가량은 왕겨 대비 5~20wt%로 한정할 수 있다. In addition, from the test results shown in [Table 1] and [Table 2] above, it can be seen that slaked lime exhibits both water resistance and antifungal performance when 5wt% or more of rice husk is added. However, when the slaked lime is added more than 20wt% compared to rice husk, the effect of enhancing the compressive strength by age is not great, so the amount of slaked lime added can be limited to 5-20wt% compared to rice husk.
또한, 본 발명은 (a) 왕겨에 소석회를 혼합하는 부패 저항 왕겨 혼합물 제조단계; (b) 고로슬래그 미분말, 석분 및 상기 왕겨 혼합물을 혼합하는 결합재 조성물 제조단계; (c) 상기 결합재 조성물에 물을 혼합하는 경량블록 조성물 제조단계 및 (d) 상기 경량블록 조성물을 형틀에 넣고 압착시키는 블록 제조단계를 포함하는 부패에 저항하는 왕겨를 포함한 경량블록 제조 방법을 함께 제공한다.In addition, the present invention (a) a step of preparing a rot-resistant chaff mixture mixing slaked lime with chaff; (B) preparing a binder composition for mixing the blast furnace slag fine powder, stone powder and the chaff mixture; (c) Light block composition manufacturing step of mixing water with the binder composition and (d) Light block manufacturing method including chaff resisting spoilage including a block manufacturing step of putting the light block composition into a mold and pressing it together do.
이 때, 상기 (a)단계는 상기 소석회를 상기 왕겨 대비 5~20wt% 혼합하고, 상기 (b)단계는 상기 고로슬래그 미분말 100중량부, 상기 석분 275~325중량부 및 상기 왕겨 혼합물 52.5~180중량부 혼합하고, 상기 (c)단계는 상기 물을 상기 고로슬래그 미분말 100중량부 대비 20~30중량부 혼합하는 것이 바람직하다.At this time, in step (a), the slaked lime is mixed with 5 to 20 wt% of the rice husk, and in step (b), the blast furnace slag fine powder is 100 parts by weight, the stone powder is 275 to 325 parts by weight, and the rice husk mixture is 52.5 to 180 Mixing by weight, the step (c) is preferably 20 to 30 parts by weight of the water compared to 100 parts by weight of the blast furnace slag fine powder.
