Coal gangue coarse aggregate strengthening technology
The invention belongs to the technical field of comprehensive utilization of solid wastes, and discloses a coal gangue coarse aggregate strengthening technology which comprises the following steps: preparing raw materials: collecting and preparing coal gangue, fly ash, cement and silica fume; proportioning: determining the proportion of each raw material according to a proportioning scheme; the cement, the fly ash and the silica fume are mixed to form a mixture, a proper amount of water is added and uniformly stirred, the uniformity and consistency of the slurry are adjusted, and the coal gangue is gradually added, so that the slurry on the surface of the coal gangue is uniform. The method comprises the following steps: taking out coal gangue, orderly arranging and separately placing the coal gangue in a tray, putting the tray in a constant-temperature humidity environment, curing to gradually harden the surface of the coal gangue, and soaking the coal gangue in a sodium silicate (Na2SiO3) solution for 24 hours after curing and drying treatment. And finally, the coal gangue is taken out and placed in a constant-temperature humidity environment for maintenance, so that the surface of the coal gangue is gradually hardened and dried. Therefore, the coal gangue, the coal ash and the silica fume can be fully recycled, so that the effects of energy conservation and environmental protection are achieved.
本发明属于固废综合利用技术领域，且公开了一种煤矸石粗骨料强化技术，包括：准备原材料：收集和准备煤矸石、粉煤灰、水泥和硅灰；配比：根据配比方案，确定各原材料比例；本发明通过混合水泥、粉煤灰和硅灰，形成混合料，同时适量加水搅拌均匀，调整浆料的均匀性和稠度，逐渐加入煤矸石，使得煤矸石表面浆料均匀。将煤矸石取出，整齐排列分开放置在托盘里，放入恒温湿度环境下，进行养护，使其表面逐渐硬化，经过养护和干燥处理后，将煤矸石放入硅酸钠(Na2SiO3)溶液中浸泡24h。最后，取出煤矸石并放入恒温湿度环境下进行养护，使其表面逐渐硬化、干燥。如此便可以充分回收利用煤矸石、粉煤灰和硅灰，从而达到了节能环保的效果。
