White Portland cement clinker and preparation method thereof
The invention relates to the technical field of white cement, and particularly discloses a white Portland cement clinker and a preparation method thereof. The white Portland cement clinker is prepared from the following raw materials in parts by mass: 38 to 42 parts of limestone, 38 to 42 parts of modified high-magnesium waste rock, 8 to 11 parts of wollastonite, 3 to 5 parts of kaolin, 3 to 6 parts of pyrophyllite, 1 to 1.5 parts of bauxite, 1 to 1.5 parts of aluminum scrap slag, 1 to 1.5 parts of borax and 0.8 to 1.4 parts of compound mineralizer. According to the invention, inorganic chemical reaction modification is carried out on the high-magnesium waste rock, the surface appearance of the high-magnesium waste rock is changed, and the surface of the high-magnesium waste rock with the original appearance is coated with a layer of loose and porous substance, so that the specific surface area of the clinker is increased, and diffuse reflection on light is increased; through the raw materials in a specific ratio, a synergistic effect is formed among the raw materials, the cost of the raw materials is reduced, the whiteness and mechanical strength of the clinker are remarkably improved, and the clinker has a relatively good market application value.
本发明涉及白水泥技术领域，具体公开一种白色硅酸盐水泥熟料及其制备方法。白色硅酸盐水泥熟料包括以下质量份数的原料：石灰石38份~42份、改性高镁废石38份~42份、硅灰石8份~11份、高岭土3份~5份、叶腊石3份~6份、铝矾土1份~1.5份、废铝渣1份~1.5份、硼砂1份~1.5份和复合矿化剂0.8份~1.4份。本发明对高镁废石进行了无机化学反应改性，改变了高镁废石的表面形貌，在高镁废石原有形貌的表面包覆了一层疏松多孔的物质，提高了熟料的比表面积，增加了对光的漫反射；通过特定配比的原料组成，使各原料之间形成协同增效作用，降低了原料成本，显著提升了熟料的白度和力学强度，具有较好的市场应用价值。
