摘　　要：随着中国“固废资源化”战略目标的逐步实施,煤气化渣资源化利用已成为煤气化产业可持续发展需要突破的重要课题。目前煤气化渣作为建筑材料的资源化利用仍需深入的研究。对已有研究成果进行综合评述是进一步深入研究的基础和前提,基于此,系统地分析和总结了中国煤气化渣作为建筑材料资源化利用的研究进展,概括出目前的利用方向主要包括煤气化渣制备砌体材料、煤气化渣掺制水泥和混凝土、煤气化渣作为道路材料以及煤气化渣作为其他建筑材料,并探讨了煤气化渣建筑材料资源化利用目前存在的问题与研究的不足,同时提出进一步研究的建议与展望。In China,the strategic goal of"solid waste recycling"is being gradually implemented.The resource utilization of coal gasification slag is very important for the sustainable development of the coal gasification industry,and the research on it has become an important research subject.Though many advances in the resource utilization of coal gasification slag as building materials have been achieved in recent years,more extensive researches and dig deeper studies in this field should be made.A comprehensive review on existing research results was the base and precondition for further studies.Based on the previous studies,the current researches of coal gasification slag as building materials in China were analyzed.Firstly,the four utilization directions of coal gasification slag as building materials were put forward,including the application as masonry materials,as the mineral additions for cement and concrete mixing,as road materials,and as other building materials.Secondly,the problem and deficiency existing were discussed.At last,some suggestions and research prospects in this field were also proposed.
