Fig. 2. Comparison of D50, D30, and D10 statistic from American Society of Testing Materials (ASTM) and Soil Science Society of America (SSSA) hydrometer analysis under ambient conditions and 30°C water bath. D50, D30, and D10 are the particle diameters when the percentage less than of the particle-size distribution curve is 50, 30, and 10%, respectively.
