Abstract

Aerial lime mortar was mixed by adding two types of admixtures that give waterproof function, and the pre-hardening characteristics were confirmed. As a result, The amount of mixing water required varies depending on the type of lime, and traditional admixtures increase or decrease the flow value depending on the type of lime. On the other hand, the longest time it took to harden is lump lime. In addition, traditional admixtures(Perilla oil) delayed the setting time in all kinds of lime, and modern admixtures(Waterproof agent) delayed the initial setting time of commercial lime, but the impact was relatively small. Also the two types of admixtures showed the effect of reducing shrinkage under most conditions, especially in powdered lime. Thus, according to the purpose and use of construction the type and amount of the admixture could be applied
