摘　　要：基于工业建筑固废资源化再生处置利用,研究以新型抗水性自修复土壤固化技术-飞灰基土壤固化剂“路液”对工业建筑固废的固化处置方法,将土壤固化剂掺入建筑固废与水泥稳定,以不同掺量作对照,分别从强度、抗水性、自修复性方面研究建筑固废固化后的材料性能。研究表明:固化剂“路液”在不同水泥掺量下均对建筑固废的强度、抗水性、自修复性有增强作用。水泥掺量为5%的再生集料添加固化剂“路液”后,7 d无侧限抗压强度高于水泥掺量为6%的再生集料不添加固化剂“路液”的强度。实验结果表明,这种粒料类固废物作为路面基层材料具有较大的工程实用性,固化剂“路液”能加强再生集料的固化作用,从而降低水泥胶凝材料的掺量,可以实现降低工程成本的目的。On the basis of the resource recycling and utilization of industrial construction solid waste,an investigation has been made of the solidification and disposal method of industrial construction solid waste by adopting a new type of water resistant self-healing soil solidification technology-fly ash-based soil curing agent“road fluid”.By adding the soil curing agent to the construction solid waste and cement for stabilization,a research is conducted on the material properties of the solidified construction solid waste from the perspectives of strength performance,water resistance performance,and self-healing performance,with different dosages used as controls.Research results show that the curing agent“road fluid”is catheterized with an enhancing effect on the strength,water resistance,and self-healing performance of construction solid waste at different cement dosages.The unconfined compressive strength of recycled aggregate with a cement content of 5%and the addition of curing agent“road fluid”after 7 days is higher than that of recycled aggregate without the addition of curing agent“road fluid”with a cement content of 6%.The experimental results show that this granular solid waste finds its great engineering practicality as a pavement base material.The curing agent“road fluid”helps to enhance the curing effect of recycled aggregates,thereby reducing the dosage of cement binder and achieving the goal of reducing engineering costs.
