In order to develop a good performance and economic repair mortar material,this paper through the prepara-tion of ceramic lime mortar,based on the setting time,drying shrinkage rate test data to determine the optimal mix ratio,and on the basis of modified by adding fiber,admixture,the system explores the mechanical properties and durability per-formance.Combined with XRD and SEM analyzed the microstructure of the material,the results show that ceramic pow-der for hydraulic lime mortar drying shrinkage decreased,with the improvement of ceramic powder,mortar setting time is shorter,18％content of ceramic powder setting time,add 2％aluminum sulfate admixtures of mortar sulfate erosion per-formance is optimal,mixed with 4％asbestos fiber to improve the frost resistance of mortar.
