Abstract:

With the improvement of historical architecture protective consciousness,preparation and experiment of a betterrestoration mortar applied in conservation for historic constructions has become a research focus at present. As a new kind ofrestoration mortar,L-MK mortar has the hydraulical property like cement as well as can compatible with historic masonrieslike traditional lime mortar. In this paper,the latest research progresses on L-MK restoration mortars were introduced; itscure reaction mechanism,proportion,curing conditions and modified property were discussed. In addition,the problems anddevelopment trends and application prospects of L-MK restoration mortars were also discussed.
