All-solid-waste low-carbon type ternary mineral gelling system and preparation method thereof
The invention belongs to the technical field of solid waste resource utilization, and provides an all-solid-waste low-carbon type ternary mineral gelling system and a preparation method thereof.The preparation method comprises the steps that coal gangue, carbide slag and desulfurized gypsum are subjected to first mixing, a first mixture and water are subjected to second mixing, and a second mixture is obtained; sequentially pressing, drying, calcining and cooling the second mixture to obtain an all-solid-waste low-carbon ternary mineral gelling system; the calcination is multi-stage calcination. According to the invention, the cement clinker is prepared by completely replacing non-renewable resources with industrial solid wastes, and calcination is carried out at different temperature intervals at different heating rates and different heat preservation time, so that full deconstruction of original mineral components of coal gangue and carbide slag and full reconstruction of all-solid-waste low-carbon ternary mineral gelling system components are realized; the resourceful treatment of the industrial solid waste is also realized; the all-solid-waste low-carbon ternary mineral gelling system has the characteristics of early strength, quick setting and quick hardening, and has a good application prospect in repair engineering.
本发明属于固废资源化利用技术领域，本发明提供了一种全固废低碳型三元矿物胶凝体系及其制备方法，将煤矸石、电石渣和脱硫石膏进行第一混合，第一混合料与水进行第二混合，得到第二混合料；将第二混合料顺次进行压制、干燥、煅烧、冷却，得到全固废低碳型三元矿物胶凝体系；煅烧为多阶段煅烧。本发明以工业固废完全替代不可再生资源制备水泥熟料，通过在不同温度区间以不同的升温速率和不同的保温时间进行煅烧，不仅实现了煤矸石、电石渣原矿物组分的充分解构和全固废低碳型三元矿物胶凝体系组分的充分重构，还实现了工业固废的资源化处理；全固废低碳型三元矿物胶凝体系，具有早强、快凝、快硬特点，在修补工程中具有很好的应用前景。
