초록
The application of reinforcing agents with hydraulic property and strength development characteristics wasstudied under conditions similar to those of mural-painting mortar made with oyster shell powder. Reinforcement mortarmade with oyster shell powder showed hydraulic properties and strength to supplement the weaknesses of natural hydrauliclime(NHL); this confirmed its possibility as a wall-reinforcing material with enough strength for preserving muralpaintings. Reinforcement mortar 1 showed hydraulic property and general characteristics of lime mortar, such asconsistency and viscosity, as well as lower strength and higher whiteness compared to an NHL product. For Reinforcementmortar 2, the original wall sample characteristics were reflected by mixing more shell produced through calcination; andit showed similar strength to that of Reinforcement mortar 1 as well as high whiteness. In measuring the contraction ratioof reinforcement mortar samples, Reinforcement mortar 1 and 2 showed more stability in property change compared tothe NHL Group.
