In previous paper Tawara, measuring the critical void ratio of the aggregate of volcanic light soil, found that volcanic light soil has sandy property; and explained one of the mechanism of the stickness of volcanic light soils with the result of that experiment.
In this paper we measured the critical void ratio of alluvial clayey loam in Konosu as same as previous paper, and found that the alluvial clayey loam also has critical void ratio, of which value is 1.24 when the lateral pressure is 0.3kg/cm2 These behaviour of alluvial clayey loam is more similar to sand than volcanic light soil. This is perhaps why the latter aggregate is easy to be destroyed when it is compressed initially.
