煤矸石基地质聚合物的制备与性能优化研究
TD849.5; 煤矸石的不合理处置会给生态系统带来巨大的压力和威胁,为了解决煤矸石再利用困难和利用率低的问题,提出利用煤矸石生产地质聚合物的高附加值策略.以未煅烧的煤矸石为原材料,采用单因素实验设计法,研究了高炉矿渣掺入量、水玻璃模数、碱激发剂添加量、液固比和初始 24 h养护温度等因素对地质聚合物基体抗压强度的影响.结果表明,初始 24 h养护温度、碱激发剂添加量和水玻璃模数对煤矸石-高炉矿渣基复合地质聚合物的性能有显著影响.通过X射线衍射分析和扫描电镜分析发现,在碱激发剂的作用下,未煅烧的煤矸石结构被破坏,与高炉矿渣协同生成水化铝硅酸钠(N-A-S-H)、水化铝硅酸钙(C-A-S-H)和...

| Abstract_FL | The unreasonable disposal of coal gangue will bring pressure and threat to the ecosystem.In order to solve the problem of difficult reuse and low utilization rate of coal gangue,the high value-added strategy of using coal gangue to produce geopolymers was put forward.In this study,uncalcined coal gangue was used as the raw material,and the effects of the addition amount of blast furnace slag,the modulus of sodium silicate,the addition amount of alkali-activator,the ratio of liquid to solid and the initial 24-hours curing temperature on the compressive strength of geopolymer matrix were studied by single factor experimental design.The results show that the initial 24-hours curing temperature,the addition amount of alkali-activator and the modulus of sodium silicate have significant effects on the properties of coal gangue-blast furnace slag based geopolymer matrix.X-ray diffraction and scanning electron microscope analysis show that the structure of uncalcined coal gangue is destroyed under the action of alkali-activator,and the dense microstructure is formed on the synergic formation of N-A-S-H,C-A-S-H and C-S-H gels with blast furnace slag.This research results provide a reasonable basis for the large-scale resourceful utilization of coal gangue. |
