固化温度对地质聚合物性能影响研究现状
Effect of curing temperature on the properties of geopolymers
【摘要】 地质聚合物作为一种新型无机胶凝材料,以其原料多为工业废渣、性能优异、应用领域广泛等优势成为众多学者的研究对象。地质聚合物的固化温度对硅铝质原料解聚和缩聚反应、体系微观结构的形成、以及固化后强度等性能都有显著的影响。综述了固化温度对地质聚合物反应速率、力学性能、胶凝产物组成和微观结构的影响,并结合固化温度对地质聚合物影响研究现状,提出了所面临的问题及后续值得关注的研究方向。
【Abstract】 As a new type of inorganic cementitious material,geopolymer has become the research object of many scholars due to its raw materials of industrial waste residue,excellent performance and wide application fields.The curing temperature of geopolymer has a significant influence on the depolymerization and polycondensation of silica-alumina raw materials,the formation of system microstructure,and the strength after curing.The effects of curing temperature on the reaction rate,mechanical properties,composition of gel products and microstructure of geopolymer were reviewed.And combined with the research status of the effect of curing temperature on geopolymer,the problems faced and the future research directions worthy of attention were proposed.
