Title:
CALCIUM ALUMINATE CLINKER USING WASTE MATERIAL AND MANUFACTURING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2011/096604
Kind Code:
A1
Abstract:
The present invention relates to a calcium aluminate clinker using waste material and a manufacturing method thereof. More specifically, the calcium aluminate clinker is manufactured by mixing at an appropriate ratio asbestos waste, ash of incinerated domestic waste, sludge from purified water, plaster, fluorite and silicon carbide, and then calcinating the mixture to produce an environmentally friendly and low-cost calcium aluminate clinker. According to the present invention, carbon dioxide emissions can be reduced during a process of manufacturing a calcium aluminate clinker by virtue of reduced calcinating temperature and by using waste material and a resultant calcium aluminate clinker is environmentally friendly and has low production cost. Further, quality degradation of a clinker itself due to alkali components can be prevented since alkali components can be neutralized, the asbestos components of harmful asbestos wastes can be removed, and high quality cement having rapid hardening properties, high strength, high liquidity, and high expansibility can be manufactured.
