摘要/Abstract

摘要： 为实现煤矸石高效资源化利用,探明煤矸石细骨料改性处理对煤矸石砂浆性能的影响,通过粉煤灰-水泥浆体包裹改性、粉煤灰-水泥浆体包裹协同CO₂矿化改性和环氧树脂包裹改性方法对煤矸石细骨料进行改性处理,研究煤矸石细骨料改性处理对煤矸石砂浆工作性能、力学性能和微观结构的影响规律,并阐明其作用机理。结果表明,与未改性的煤矸石砂浆相比,改性处理后煤矸石砂浆的吸水率、力学性能、微观结构均得到改善。环氧树脂包裹改性效果最优,煤矸石砂浆的抗压强度和弹性模量分别提升了28.8%、32.4%,吸水率降低了25.3%。这是由于环氧树脂硬化引起骨料的整体强度提升,骨料孔隙率降低,界面过渡区改善,从而提升煤矸石砂浆的力学性能。

Abstract: To realize efficient resource utilization of coal gangue, the influences of modification treatments on performance of coal gangue mortar using coal gangue fine aggregate were investigated. Coal gangue fine aggregate was modified through fly ash-cement slurry encapsulation modification, CO₂ mineralization combined with fly ash-cement slurry encapsulation modification, and epoxy resin encapsulation modification methods. The aim was to study the influences of these coal gangue fine aggregate modifications on the working performance, mechanical properties, and microstructure of coal gangue mortar to elucidate their mechanisms. The results demonstrate that compared to unmodified coal gangue mortar, the modified coal gangue mortar exhibits improved water absorption, mechanical properties, and microstructure. Among these modifications, epoxy resin encapsulation modification proves most effective with a 28.8% increase in compressive strength and a 32.4% increase in modulus of elasticity, while reducing water absorption by 25.3%. This can be attributed to the enhanced overall strength and reduced porosity of aggregates due to epoxy resin hardening, as well as improvements in interfacial transition zones, leading to enhanced mechanical properties.

Key words: coal gangue fine aggregate, fly ash-cement paste, epoxy resin, CO₂ mineralization, mechanical property, mortar, interfacial transition zone
