概要

The results of an experiment on the void content of no-fines concrete and its influence on the compressive strength and load-displacement relationship of concrete are reported in this paper. Four different sizes of coarse aggregate of 5-10, 10-15, 15-20, and 5-20 mm, and three absolute volume ratios of paste to aggregate of 25, 2$ and 35 percent for a given size o」 aggregate were used. The method proposed by JCI Technical Research Committee on Ecological Concrete (1) was used to measure the void content. The results of measured void content show a small variation. The effect of changing paste volume in no-fines concrete on the void content depends on the size of aggregate.
