1. A known weight of dry soil (50 g of prepared dried, crushed & sieved) fine-grained sample into a beaker. 2. Add 5.00 g of deflocculant (soap). 3. Add water to beaker until it is about half full and stir well 4. Transfer solution to metal mixing cup 5. Add water to cup until it is about half full. 6. Mix for one minute. 7. Transfer solution to hydrometer jar, 8. Add clean tap water to the jar, up to the 1,000 ml mark. 9. Set jar down carefully immediately record this time as the START time. 10. Take temperature and hydrometer readings at the following elapsed times: 1, 2, 4, 8,... minutes after the START time. 11. Determine the corrected hydrometer readings and values of L, K, a and R from the tables. (tables1,2 and 3) and then D(mm). Dmm = KVI/T Note: D is the particle diameter K is a coefficient simplified from the assumed fluid and particle densities, and temperature. Lis the length (cm) the bulb has dropped in time T (mins) R is the corrected hydrometer reading. The hydrometer reading must be corrected to account for changes in fluid density due to dissolved minerals, temperature changes, and the addition of a deflocculating agent (soap) a is a correction coefficient for the relative density of the particles. 12. Determine percent passing and plot a Grain Size Distribution curve .(Based on formula below) R P% = x 100 MS Note : P is the percent smaller (still in suspension) Ms is the original sample mass. 13. Plot a fully labelled grain-size distribution curve (logarithmic scale) by excel. 14. Identify the % gravels, sands and fines (Based on top table) 15. Uniformity coefficient (Cu), Cu = D60/D10. 16. Coefficient of curvature (Cc), Cc = (D30)2/(D60xD10) 17. Classify the soil using USCS and MIT.
