Description

火山灰를 이용한 재생모래의 제조방법{omitted}Manufacturing method of recycled sand using 火山灰

영국의 고고학자 토마스 리키는 인류를 멸망으로 이끄는 것은 핵전쟁이 아니라 인간이 버린 쓰레기와 폐수라고 한것처럼 환경문제는 생존문제이며 재활용산업은 제2의 산업혁명이라 할수 있다.British archaeologist Thomas Ricky says that environmental problems are a survival problem and recycling industry is the second industrial revolution, as it is not nuclear war, but human waste that wastes humans.

이와 같이 심각한 환경문제는 재활용하는 방법이외에는 다른 방법이 없다고 할수 있다. 본 발명은 처리 곤란한 화산재를 이용하여 재생모래를 만들어 재활용하는 것에 목적이 있다.This serious environmental problem can be said that there is no other way than recycling. An object of the present invention is to make and recycle recycled sand using volcanic ash which is difficult to treat.

본 발명은 cao등이 부족한 火山灰의 물성을 보충하여 보다 강도가 큰 재생모래를 저렴하게 생산할 수 있게 한 것이다. 즉 火山灰 시멘트의 혼합물에 소석고를 첨가하여 성형물의 초기강도를 증가시키어 실용성이 높은 재생모래를 제조하는 방법이다.The present invention is to supplement the physical properties of 火山灰 lacking cao and the like to be able to produce a higher-strength recycled sand at a low cost. In other words, by adding calcined gypsum to the mixture of 火山灰 cement, the initial strength of the molding is increased to produce recycled sand with high practicality.

火山灰에 시멘트를 배합한것에 소석고를 배합하면 광물 조성중의 Ettringite가 생성하여 초기강도를 상승시키며 후기 강도는 시멘트중 Tobermolete의 증가로 보완하게 된다. 상기 Ettringite의 생성 반응식은 다음과 같다. When calcined gypsum is mixed with cement in 火山, Ettringite is formed in the mineral composition to increase the initial strength, and later strength is compensated by the increase of Tobermolete in cement. The reaction scheme for generating Ettringite is as follows.

C3AC 3 A

3CaO ·AI2 + 3CaSO4 + xH2O → C3SO4 ·3IH2 O3CaOAI 2 + 3CaSO 4 + xH 2 O → C 3 SO 4 3IH 2 O

(화산회 + 시멘트) + (소석고) + 물 → (Ettringite. 광물조성)(Volcanic ash + cement) + (calcite) + water → (Ettringite.mineral composition)

상기 Tobermolete생성 반응식은 다음과 같다.The Tobermolete generation scheme is as follows.

火山灰를 재활용하여 재생모래를 제조함에 있어 火山灰에 시멘트만으로 재생모래를 사용할 수 없는것에도 초기 강도를 증진되도록 소석고를 시멘트와 같이 사용하는 제조 방법이다.In the manufacture of recycled sand by recycling 火山灰, it is a manufacturing method using calcined gypsum together with cement so that the initial strength can be improved even if the recycled sand cannot be used only with cement in 火山灰.

火山灰의 특성을 이용하여 화산회에 시멘트와 소석고를 혼합된것에 적량의 물로 교반하여 水和反應이 일어나서 재생모래가 되도록 제조하는 것으로 본 발명이 속하는 기술분야 및 그 기술의 종래에 상술되어 있다.It is described in the prior art and the prior art of the present invention to manufacture such that a mixture of cement and calcined gypsum in volcanic ash using a characteristic of 火山 to stir with an appropriate amount of water to generate water and regenerate sand.

처리 곤란한 火山灰를 재활용하는 것으로 발명의 목적에서 상술한 데로 火山灰의 처리문제가 해결되는 효과이다.It is an effect that the problem of the disposal of 火山灰 is solved as described above for the purpose of the invention by recycling the difficult 火山灰.
