Desulfurized gypsum shrinkage-compensating all-solid waste cementing material and preparation method thereof
The invention discloses an all-solid waste cementing material with shrinkage compensated by desulfurization gypsum and a preparation method of the all-solid waste cementing material. The all-solid waste cementing material comprises the following components: desulfurization gypsum, carbide slag, steel slag, silicon-calcium slag, coal gangue, fly ash, blast furnace slag, aluminum ash, flue gas desulfurization sludge, red mud, desulfurized petroleum coke slag, sulfuric-acid slag and phosphogypsum. According to the prepared all-solid-waste cementing material with the desulfurization gypsum for shrinkage compensation, all the raw materials are from industrial solid waste, pollution to the environment and harm to the human body caused by bulk solid waste are effectively solved, and the modern industrial requirements for reducing environmental pollution, improving the resource utilization rate and improving the living environment of people are met. Meanwhile, the desulfurization gypsum serving as an admixture is mixed with the full-solid waste cementing material clinker, so that the shrinkage compensation capability of the full-solid waste cementing material clinker can be improved. The composite material can be used in first-aid repair and rush-building projects, seawater corrosion-resistant projects, anti-seepage projects and the like, and can better avoid the phenomena of corrosion, leakage, shrinkage cracking and the like in the projects.
本发明公开了一种脱硫石膏补偿收缩的全固废胶凝材料及其制备方法，包括以下成分：脱硫石膏、电石渣、钢渣、硅钙渣、煤矸石、粉煤灰、高炉矿渣、铝灰、烟气脱硫污泥、赤泥、脱硫石油焦渣、硫酸渣、磷石膏。本发明中制备的一种脱硫石膏补偿收缩的全固废胶凝材料实现了原材料全部来自工业固体废弃物，有效解决了大宗固废对环境的污染和对人体的危害，有利于实现减少环境污染、提高资源利用率、改善人们生活环境的现代工业化的需求。同时，脱硫石膏作为掺合料与全固废胶凝材料熟料混合可提高其补偿收缩的能力。可用在抢修抢建工程、抗海水腐蚀工程和防渗工程等方面，能够较好的避免在工程中出现的腐蚀、渗漏和收缩开裂等现象。
