1.A strata of clean, light-colored quartz sand located below the groundwater table has a moisture content of 25.6%. The minimum and maximum void ratios of this soil are 0.380 and 1.109, respectively. Select and apporpriate value of Gs for this soil and compute its relative density.
2.The total density of a moist soil was determined to be 1760 kg/m3 when its water content was 10.0%. Assume the specific gravity is 2.7. Given this information, determine
(a) the phase diagram of the soil,
(b) the void ratio,
(c) the porosity,
(d) the dry density, and
(e) the saturated density.
