摘要
文中基于煤矸石母岩性质,开展煤矸石作骨料时母岩物化特性评价研究,结合现有标准规范和相关研究,从煤矸石母岩的化学组成、矿物组成、热稳定性、抗压强度、体积稳定性和环境安全性等材料基本性质的角度全面评价了煤矸石作骨料的可行性,形成了适用于制备骨料的煤矸石母岩评价方法,为煤矸石的资源化利用提供切实可行的参考途径。
Based on the properties of coal gangue parent rock,this paper carries out the evaluation research on the physicochemical properties of coal gangue parent rock when coal gangue is used as aggregate.Combined with the existing standards and related research,the feasibility of coal gangue as aggregate is comprehensively evaluated from the basic properties of coal gangue parent rock,such as chemical composition,mineral composition,thermal stability,compressive strength,volume stability and environmental safety.The evaluation method of coal gangue parent rock suitable for the preparation of aggregate is formed,which provides a feasible reference way for the resource utilization of coal gangue.
