Unformatted text preview: 8. Fill the cylinder to 15.0 inches. 9. Let the material stand for 20 minutes. 10. Read and record the level at the top of the clay suspension. Record sedimentation time. If this takes over 30-min, rerun. 11. After clay reading, lower the weighted foot assembly into the cylinder. Subtract 10-in from the level indicated by the top edge of the indicator. This is your sand reading. 12. Calculate the sand equivalency value as the next highest whole number if it is a decimal. 13. Calculate the average value. Calculations Sand Equivalency 100 = Clay Sand SE Significance and Use The test determines the amount, fineness, and character of the clay materials present in the aggregate....
