Abstract：A special repairing adhesive for aerated concrete panel was prepared with re-dispersible powder hydroxypropyl methylcellulose and retarder added in gypsum slurry.The effect of the raw materials with different amount on the performance of the setting time,compressive strength,adhesive shearing strength,water retention and volume expansion rate of the repairing adhesive was studied and the production trial was carried out.Results showed that this repairing adhesive had good performances of suitable hardening,strong bonding force,volume stability and good water retention,which was almost no chromatic aberration with the aerated concrete and has good appearance.
