Abstract

Several studies have been made by the author on improvement of vacuum processing method for slab concrete so far. From the earlier studies, it has been shown that the most effective timing for vacuum processing is just after the end of bleeding. However, the finishing time of bleeding is influenced by many factors. In this study, the degree of bleeding has been evaluated from the consistency of fresh concrete, and a simple evaluation method for starting time of vacuum processing has been newly proposed.
