Cement prepared from marble waste residues
The invention discloses cement prepared from marble waste residues. The cement comprises the following substances in percentage by weight: 79.95% of limestone; 10.38% of alumina; 6.74% of ironstone tailings; and 2.93% of marble waste residue. The marble waste residues are used for cement production, so that the marble waste residues are utilized, recycling of the marble waste residues is achieved, full utilization of resources is achieved, the problems of land occupation and environmental pollution caused by artificial marble waste residues are solved, the production cost of cement enterprises is reduced, resources are recycled, waste is turned into wealth, and the method is suitable for industrial production. And good economic benefits and social benefits are obtained. Research finds that the artificial marble waste residues are high in silicon dioxide content and replace sandstone to be used as a siliceous raw material, the exploiting strength of the sandstone is relieved, the diversification of raw material ingredients is expanded through effective ingredients of the artificial marble waste residues, and the cement performance can be easily exerted. The artificial marble waste residue does not harm the chemical and physical properties of the cement clinker, and can meet the daily production of cement enterprises.
一种利用大理石废渣制备的水泥，包括如下重量百分比的物质：石灰石79.95％；铝土10.38％；铁石尾砂6.74％；大理石废渣2.93％。本发明将大理石废渣用于水泥的生产，从而使大理石废渣得到利用，实现大理石废渣的回收利用，从而实现资源的充分利用，解决了人造大理石废渣造成的占地和环境污染问题，又降低了水泥企业的生产成本，属于资源再利用，变废为宝，获得了良好的经济效益与社会效益。经过研究发现，人造大理石废渣二氧化硅含量较高，替代了砂岩作为硅质原料使用，减轻了对砂岩的开采力度，人造大理石废渣的有效配料拓展了生料配料的多元化，易于水泥性能的发挥。人造大理石废渣没有对水泥熟料的化学物理性能带来危害，可以满足水泥企业的日常生产。
