jaue2016063: Study on Environmental Performance Investigations into Scallop Shell Lime for Interior Material Use

Abstract

About 360,000 tons of scallop are unloaded in Japan now, and most of them are concentrated in Hokkaido. The illegal dumping of the scallop shell became the problem, but the recycling rate largely rose by subsidies in late years. However, subsidies are not necessarily continuing permanently.
It was found that scallop shell lime is a natural material with little environmental load and highenvironmental performance. In addition, water resistance was confirmed by polished finish.
In this paper, water resistance and environmental performances are compared between scallop shell lime and lime.
From the result of the examination, it was found that the examination body of the scallop shell lime with polished finish could have both humidity control effect and water resistance performance. In addition, in the investigation about the water resistant mechanism, a prediction that expression of water resistance is influenced by the speed of carbonation was provided.
