Abstract

A high performance lightweight aggregate which has been recently developed has higher strength and lower absorption than conventional artificial lightweight aggregates. The purpose of this study is to investigate the fracture mechanism of concrete made with the high performance lightweight aggregate. We mainly focused on the combination of matrix strength and aggregate strength. As the result, it was clarified that the fracture energy of the high performance lightweight concrete depends on the strength of matrix and aggregate and the combination of their strengths as well as unit volume, shape and size of aggregate.
