✦ Synopsis

A porous material is assumed to be made up of many porous bodies which contain various size pores and are parallelly connected. The quantitative relationship between strength and pore-size distribution of porous materials was derived based on the Griffith's theory and the theory of composite, and the block diagram of computer program used to treat this relationship was also put out. Various cement mortar samples and lime-sand silicate concrete samples were tested by using the model of cylindrical pores crossed perpendicularly in three-dimentional space, s~ne as the model in mercury porosimetry. The results show that there is much correspondence between the actual strength and the strength calculated based on the relationship derived in this paper.
