摘要
为实现煤矸石的合理利用,结合集配、压碎值、膨胀崩解性分析煤矸石的物理性质,通过化学组成、活性等分析煤矸石化学性质,采用不同无机结合料对其进行针对性改良。分析煤矸石及石灰、粉煤灰混合料作用机理,通过无侧限抗压强度试验及回弹模量试验对煤矸石材料路用性能进行评价。
In order to realize the reasonable use of coal gangue,combined with the set,crushing value,swelling disintegration analysis of the physical properties of gangue,through the chemical composition of gangue,activity and other analysis of chemical properties,the use of different inorganic binding materials for its targeted impro vement.The action mechanism of coal gangue,lime and fly ash mixture is analyzed,and the road performance of coal gangue material is evaluated through unconfined compressive strength test and springback modulus test.
