High-sulfur cement clinker and method for producing high-sulfur cement clinker
The invention discloses a high-sulfur cement clinker and a method for producing the high-sulfur cement clinker. The high-sulfur cement clinker is prepared from the following raw materials in parts by weight: 200-320 parts of limestone; 4 to 10 parts of silica; 3 to 8 parts of lamprophyres; 2 to 8 parts of copper slag; and 2 to 12 parts of modified phosphogypsum. The copper slag is used for replacing an iron raw material in the cement raw material and is calcined to prepare the cement clinker; the used modified phosphogypsum is waste residues of a power plant, CaSO4 in the modified phosphogypsum is partially decomposed to generate CaO, and the CaO replaces part or all of limestone to serve as a calcium raw material, so that resource utilization of solid wastes can be realized.
本发明公开了一种高硫水泥熟料以及生产高硫水泥熟料的方法,其制备包括下述重量份的原料:石灰石:200份~320份;硅石:4份~10份;煌斑岩:3份~8份;铜渣:2份~8份;改性磷石膏:2份~12份。本发明利用铜渣代替水泥生料中铁质原料,经过煅烧制成水泥熟料;使用的改性磷石膏为电厂的废渣,其中的CaSO4部分分解生成CaO,代替部分或全部石灰石作为钙质原材料,可以实现固废的资源化利用。
