Influence on cold resistance by pore introduction into ceramics building materials

Abstract

Water retentivity is necessary to ceramics building materials for pavement and exterior to restrain heat island effect. However, this property tends to bring about a cold resistant fall at the same time. Therefore some size of pore were introduced into the structure of pavers for the purpose of permitting the volume expansion of the water by freezing in this study. It was suggested that pores of suitable size improved cold resistance of them.
