Review on Feasibility Analysis of Coal Gangue Aggregate Parent Rock Properties
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,min-eral composition,thermal stability,compressive strength,volume stability and environmental safety.The evaluation method of coal gangue par-ent rock suitable for the preparation of aggregate is formed,which provides a feasible reference way for the resource utilization of coal gangue.
