Description

황토를 주 재료로 한 경량 단열콘크리트제의 제조방법Manufacturing Method of Lightweight Insulating Concrete Made mainly of Ocher

본 발명은 천연의 원적외선 방사체인 황토흙을 주 재료로 한 경량 단열콘크리트제의 제조방법에 관한 것이다.The present invention relates to a method for producing a lightweight insulating concrete product based on ocher soil which is a natural far-infrared radiator.

종래에는 바닥 타설재나 바닥 마감재 시공시 주로 시멘트만을 사용하여 경량 단열콘크리트 및 마감몰탈을 시공하여 왔으나 이러한 시공법에 의해 축조된 바닥은 난방열을 통하여 강알카리성의 시멘트 유해물질이 인체에 작용하는 요인으로 결정되어 인체에 많은 영향을 줄 뿐만 아니라 단연효과도 미흡하였으며 축열도 되지 않아 방바닥이 빨리 식어버리는 문제가 있었다. 이 때문에 종래 전통적인 시멘트 바닥난방 시공시에는 축열의 목적으로 주로 콩자갈을 채워 시공하였는데 이는 시공비 상승을 초래하였고 알칼리 환경으로 인한 문제, 예컨대 취침 후의 두통, 몸이 무겁거나 결리거나 무기력해지는 문제 등에 대해서는 별다른 해결책을 강구하고 있지 못하다.Conventionally, lightweight insulation concrete and finishing mortar have been constructed using only cement for the construction of floor pour or floor finishing materials. However, the floor constructed by this construction method is determined as a factor that strongly alkaline cement harmful substances act on the human body through heating heat. Not only had a lot of effects on the human body but also did not have a far-reaching effect, and there was a problem that the floor quickly cooled down because it did not accumulate. For this reason, the conventional cement floor heating construction was mainly filled with soybean gravel for the purpose of heat storage, which resulted in an increase in construction cost, and it was very different from problems caused by the alkaline environment, such as headaches at bedtime, heavy body, stiffness, and lethargy. There is no solution.

본 발명은 종래 시멘트를 주 재료로 하여 시공하였던 바닥 마감의 문제점을 해결하기 위하여 천연의 무기소재이며 인체에 유익한 원적외선 방사물질인 황토흙을 이이용한 새로운 바닥시공재 제조방법을 제공하는 것을 목적으로 한다.An object of the present invention is to provide a new flooring material manufacturing method using the yellow soil, which is a natural inorganic material and far-infrared radiation material beneficial to the human body in order to solve the problem of the floor finish that was conventionally constructed as a main material. .

이하, 본 발명에 따른 황토흙을 주재료로 한 경량 콘크리트 단열재의 시공을 첨부도면 제2도에 의하여 설명한다.Hereinafter, the construction of a light weight concrete insulation material based on ocher soil according to the present invention will be described with reference to the accompanying drawings.

본 발명에 따른 황토 경량단열콘크리트(2)는 건물의 구조체인 스라브(Slab)(1) 위에 타설되는 것으로서, 황토 경량 단열콘크리트제(650㎏/㎥)과 적당량의 물(약 480리터/㎥)과 광물성 또는 동물성 기포액을 1 : 40으로 물에 희석하여 (82리터/㎥)을 기포발생기로 통하여 발생시킨 기포슬러리를 혼합하여 7㎝~9㎝ 두께로 타설하여 수평마감하고 3일~5일 양생시킴으로써 내부에 무수한 기포군(4)이 형성된 황토 경량 단열콘크리트층을 얻는다. 이러한 황토경량 단영콘크리트는 비중이 약 430㎏/㎥에 불과하여 건축물의 하중을 그케 감소시킬 수 있는 경량가재이며, 상층에서 발생하는 소음을 흡음하므로 소음이 아래층으로 퍼지는 것을 막아준다. 한편 열전도율은 0.085㎉/㎡h℃~0.068㎉/㎡h℃로써 충분한 단열의 효과를 얻을 수 있으며, 특히 황토흙의 특성으로 한번 복사축열된 열을 서서히 방출하므로 방이 쉽게 식지 않고 보온성이 양호하여 에너지 절약효과를 볼 수 있다.The ocher lightweight insulating concrete 2 according to the present invention is placed on a slab (1), which is a structure of a building, and an ocher lightweight insulating concrete agent (650 kg / m 3) and an appropriate amount of water (about 480 liters / m 3) Dilute the mineral or animal bubble with water at 1:40 and mix (82 liter / ㎥) bubble slurry produced by the bubble generator to pour it into 7cm ~ 9㎝ thickness to finish horizontally. By curing, the ocher lightweight insulating concrete layer having numerous bubble groups 4 formed therein is obtained. Such ocher lightweight Danyoung concrete has a specific gravity of only 430 ㎏ / ㎥ is a lightweight lobster that can significantly reduce the load of the building, and absorbs the noise generated from the upper floor to prevent the noise from spreading to the lower floor. On the other hand, the thermal conductivity is 0.085㎉ / ㎡h ℃ ~ 0.068㎉ / ㎡h ℃, and sufficient heat insulation effect can be obtained. In particular, the characteristics of ocher soil gradually radiate heat once radiated and regenerated, so the room is not easily cooled and the heat insulation is good. Savings can be seen.

한편, 본 발명에 따른 황토 경량단열콘크리트층(2) 위에 도포되는 황토마감몰탈(3)은 전술한 바와 같은 공정을 통해 얻어진 황토마감몰탈제(720㎏/㎥)에 건조된 모래(725㎏/㎥)와 적당량의 물(약540리터/㎥)를 혼합한 몰탈을 즉시 이송하여 황토 경량단열콘크리트(2)위 온수파이프(5)를 배관해 놓은 곳에 3.5㎝~5㎝ 두께로 타설하여 일정한 시간경과 후 마감 미장작업으로 마무리하여 시공된다.On the other hand, the loess finishing mortar (3) is applied on the loess lightweight insulating concrete layer (2) according to the present invention sand (725 kg / dried on the loess finishing mortar (720 kg / ㎥) obtained through the process as described above ㎥) and a suitable amount of water (approximately 540 liters / ㎥) are transferred immediately to a place where the hot water pipes (5) on the ocher lightweight insulating concrete (2) are piped to a thickness of 3.5㎝ ~ 5㎝ for a certain time. After completion, it is finished by finishing plastering work.

본 발명은 종래 주로 시멘트만을 사용하여 시공하였던 건축물 바닥시공 구조 및 재료의 단점들을 착안하여 발명한 것으로서 경량이고 가격이 저렴하여 널리 실용화 시킬 수 있는 효과가 있으며 비알칼리 재료로서 인체에 유익하고 친화적인 천연소재를 사용한 것이어서 산업상 실용화가 크게 기대되는 유용한 발명이다.The present invention is invented by focusing on the shortcomings of the building floor construction structure and materials that were conventionally constructed using only cement, it is light and low in cost, and can be widely used. Since the material is used, it is a useful invention that is expected to be industrially widely used.
