Preparation method of coal gangue ceramsite aggregate with electromagnetic wave absorption function and concrete
The invention relates to the field of building materials, in particular to a preparation method of coal gangue ceramsite aggregate with an electromagnetic wave absorption function and concrete.The preparation method comprises the steps that ferroferric oxide powder and water are mixed according to the mass part ratio of (1-3): 100, a dispersing agent is added into the mixed solution, and suspension A is obtained; an alkaline solution and water glass are added into the suspension A, the suspension A is continuously stirred in the process of adding the alkaline solution and the water glass, uniform stirring is conducted after adding is completed, a suspension B is obtained, and the pH of the alkaline solution is larger than or equal to 12; performing ultrasonic dispersion treatment on the suspension B in an ultrasonic dispersion instrument to obtain a suspension C; and uniformly mixing and stirring the suspension C and the coal gangue ceramsite, standing, and filtering to obtain a precipitate, namely the coal gangue ceramsite aggregate with the electromagnetic wave absorption function. The coal gangue ceramsite is prepared by taking the coal gangue as a basic material, and the prepared coal gangue ceramsite is applied to the concrete, so that the electromagnetic wave absorption effect of the concrete is improved while the coal gangue solid waste is utilized.
本发明涉及建筑材料领域，涉及具有电磁波吸收功能的煤矸石陶粒骨料制备方法及混凝土，制备时将四氧化三铁粉末和水按照1‑3:100的质量份数比混合，并向混合液中加入分散剂得到悬浮液A；再向悬浮液A内加入碱性溶液、水玻璃，添加碱性溶液及水玻璃过程中持续搅拌悬浮液A，添加完成后搅拌均匀得到悬浮液B，碱性溶液的pH≥12；对悬浮液B在超声分散仪中进行超声分散处理，得到悬浮液C；将悬浮液C和煤矸石陶粒进行混合搅拌均匀，静置后过滤得到沉淀物即为具有电磁波吸收功能的煤矸石陶粒骨料。本发明以煤矸石作为基础材料制备得到煤矸石陶粒并将制备得到的煤矸石陶粒应用到混凝土中实现煤矸石固废利用的同时增加混凝土吸收电磁波的效果。
