Abstract

본 발명의 내용을 요약하면, 현재까지 칼슘알루미노썰페이트는 시멘트의 팽창제 분야에 국한하여 응용되었을뿐 일반적인 시멘트의 수화기구에는 사용할 수 없는 조성광물로 규정되어 왔다.To summarize the contents of the present invention, calcium aluminosulfate has been applied to the field of cement swelling agents, but has been defined as a composition mineral that cannot be used in general cement hydration equipment.

즉 종래에 조합원료를 저온소성(1,000~1,200℃)하여 얻어진 칼슘알루미노썰페이트클링커는 시멘트 팽창제 제조에만 사용되었다.That is, the calcium aluminosulfate clinker obtained by low-temperature firing (1,000 to 1,200 ° C.) in the prior art was used only for the manufacture of cement expanders.

그러나 본 발명의 칼슘알루미노썰페이트클링커는 조합원료의 배합비를 조절하고 이를 고온소성(1,250~1,400℃)하여 종래와는 전혀 다른 초속경시멘트제조의 조강제로서의 용도를 개발함으로써 종래의 용도 개념을 일축하였다.However, the calcium aluminosulfate clinker of the present invention adjusts the mixing ratio of the raw materials and high temperature firing (1,250 ~ 1,400 ° C.), thereby excluding the conventional concept of use by developing the use as a coarse additive for ultra-fast cement production. It was.

본 발명에 의하여 제조된 칼슘알루미노썰페이트클링커는 초속경시멘트제조에 단독으로 사용되는 것이 아니라 주재료인 보통시멘트에 혼용함으로써 제조 원가면에서 매우 경제적인 특징으로 가지고 있다.Calcium aluminosulfate clinker produced according to the present invention is not used alone for the production of ultra-fast cement, but has a very economical feature in terms of manufacturing cost by mixing it with ordinary cement which is the main material.
