일반적으로 옹벽은 콘크리트, 석조, 흙 등으로 구성된 블록에 의해 여러 가지 형태 및 방법으로 축조된다. 즉 복수 개의 블록이 좌우로 밀착된 상태에서 상부에 다수의 블록이 적층되는 형태로 축조되어 옹벽을 구축하게 되는데, 직선 또는 오목 및 블록한 곡선을 이루는 등 조경적인 활용을 고려하여 여러 축조방법으로 옹벽을 축조하고 있다.In general, retaining walls are constructed in various forms and methods by blocks composed of concrete, masonry, soil, and the like. In other words, a retaining wall is built by constructing a plurality of blocks stacked on top in a state in which a plurality of blocks are closely attached to the left and right. is celebrating
콘크리트 블록으로 축조된 옹벽은 경관을 해칠 뿐 아니라, 식물이 자랄 수 있는 공간이 없어 결국 생태계의 파괴가 일어나는 문제가 있다. 또한, 콘크리트블록의 주재료인 시멘트는 제조시 많은 천연자원과 에너지가 소비되어야만 하는 단점도 있다.Retaining walls made of concrete blocks not only harm the landscape, but also have a problem in that the ecosystem is destroyed because there is no space for plants to grow. In addition, cement, the main material of concrete blocks, has a disadvantage in that a lot of natural resources and energy must be consumed during manufacturing.
또한, 흙, 황토 등을 이용한 블록으로 축조된 옹벽은 자연 친화적이며, 식물이 자랄 수 있는 공간을 제공하는 등의 장점이 있다. 그러나 흙, 황토 등을 주재료로 하는 블록은 강도가 좋지 못하고, 장기적인 내구성이 현저히 떨어지는 등의 문제가 있다. In addition, the retaining wall constructed with blocks using soil, loess, etc. is friendly to nature and has advantages such as providing a space for plants to grow. However, blocks made of soil, loess, etc. have problems such as poor strength and significantly poor long-term durability.
이러한 문제를 해소하기 위하여 대한민국 공개특허 제10-2016-0033914호에서는 마사토, 고로 수쇄 슬러그, 생석회, 석고, 백반 등을 혼합하여 강도가 증가된 을 친환경 블록을 제안하였다.

한편, 채취하여 모래를 생산하는 과정에서는 약 10% 내지 약 20%의 마사토 슬러지가 발생한다. 이러한 마사토 슬러지는 적치되거나 매립하여 폐기하는데, 적치 및 매립시 자연 경관을 훼손시키고, 주변의 토양 및 지하수를 오염시키는 문제가 있다.On the other hand, in the process of collecting and producing sand, about 10% to about 20% of Masato sludge is generated. Such Masato sludge is piled up or disposed of in a landfill, but there is a problem of damaging the natural landscape and contaminating the surrounding soil and groundwater during the pileup and landfill.
따라서, 자원의 재활용 차원에서 마사토 슬러지를 다량으로 소비할 소비처 확보가 절실한 상황이다.Therefore, in terms of recycling resources, it is urgent to secure a place to consume Masato sludge in large quantities.
따라서, 본 발명의 목적은 강도, 내구성 등의 물성이 우수하면서도, 생태 안정성을 도모할 수 있는 마사토 슬러지를 이용한 친환경 보강토블록을 제공하는 데 있다.Accordingly, an object of the present invention is to provide an eco-friendly reinforced soil block using masato sludge that can promote ecological stability while having excellent physical properties such as strength and durability.

먼저, 상기 마사토 슬러지는 마사토로부터 모래를 분리하여 발생되는 것이다. 더욱 구체적으로 마사토에서 모래를 분리하기 위하여 마사토에 물을 첨가하여 교반한 혼합물을 사이크론에 통과시키면 0.5mm~7mm 크기 범위에서 세사(0.5~3mm), 중사(3~5mm), 왕사(5~7mm), 모래와 실트질 초미세사(0.5mm이하)를 함유한 혼탁수로 분리되고, 분리된 혼탁수를 정치조에 정치시키면 초미세사(0.5mm이하)가 함유된 슬러지를 얻게 되고 이 슬러지를 필터 프레스로 압착하면 수분함량 30~40％의 슬러지를 얻게 되는데, 본 발명은 이를 수분 함량이 15~20wt%가 되도록 건조한 것을 의미한다. First, the masato sludge is generated by separating sand from masato. More specifically, in order to separate sand from masato, when the mixture stirred by adding water to masato is passed through a cyclone, fine (0.5-3mm), medium (3-5mm), and fine (5-5 mm) threads in the size range of 0.5mm-7mm. 7mm), it is separated into turbid water containing sand and silt-like ultrafine sand (0.5mm or less), and when the separated turbid water is left in a political tank, sludge containing ultrafine sand (0.5mm or less) is obtained, and this sludge is filtered When compressed with a press, sludge having a moisture content of 30 to 40% is obtained, and the present invention means that the sludge is dried to a moisture content of 15 to 20 wt%.
이러한 마사토 슬러지는 일반적인 황토, 흙 등에 비하여 점토 성분이 많아 점착성이 우수하여, 기타 다른 재료들과의 결속력을 강화함으로써, 종래 황토나 흙으로 구성된 보강토블록에 비하여 우수한 강도를 확보할 수 있도록 한다. 또한, 환경친화적 재료로서 보강토블록의 외관을 해치지 않으면서도, 생태 안정성을 도모할 수 있다. 이하, 중량부는 상기 마사토 슬러지 100중량부를 기준으로 한다. This Masato sludge has more clay components than general loess, soil, etc., and has excellent adhesion, so that it can secure superior strength compared to conventional reinforced soil blocks composed of loess or soil by strengthening the binding force with other materials. In addition, as an environmentally friendly material, it is possible to promote ecological stability without compromising the appearance of the reinforced soil block. Hereinafter, parts by weight are based on 100 parts by weight of the Masato sludge.

This fly ash is used as a solidifying agent, and solidifies the Masato sludge in a binding state to express strength.
상기 플라이 애쉬는 상기 마사토 슬러지 100중량부를 기준으로, 10~50중량부로 사용됨이 바람직한데, 그 사용량이 10중량부 미만이면 고화재로서의 역할이 충분하지 못하고, 50중량부를 초과하더라도 더 이상의 증진된 효과가 없어 경제성이 떨어지기 때문이다.The fly ash is preferably used in an amount of 10 to 50 parts by weight based on 100 parts by weight of the Masato sludge. If the amount is less than 10 parts by weight, the role as a solidifying material is not sufficient, and even if it exceeds 50 parts by weight, further enhanced effect Because there is no economy, the economy is low.
