Impact compressive response of dry sand
Witryna31 paź 2024 · As compared with dry soils, water plays more significant role, for load-bearing capability than the sand grains. The soil with lower clay/sand ratios has stiffened the mechanical properties under water saturated state, and pure clay and pure sand have reduced mechanical properties. 15.4 Conclusions Witryna1 cze 2009 · Abstract.
