DETERMINATION OF DRY DENSITY BY SAND REPLACEMENT METH

S NO. DESCRIPTIONOBSERVATI

1 2

A Determination of Mass of sand in the cone

1) Mass of sand (+ cylinder) before pouring M1 10550

2) Mean mass of sand in cone M2 445

B Determination of Bulk density of sand3) Volume of calibrating container V 1000

4) Mean mass of sand(+cylinder) after pouring M3 8655

5) Mass of sand filling calibrating container = M1 - M3 - M2 1450

6) Bulk Density of sand Ys = M1 - M3 - M2/V 1.45

C Bulk Density of soil

7) Mass of wet soil from the hole M 2234

8) Mass of sand (+ cylinder) after pouring in the hole M4 8512

9) Mass of sand in the hole = M1 - M4 - M2 1593

10) Bulk density of soil(y) = M/( M1 - M4 - M2)*( M1 - M3 - 2.03

D Water Content Determination11) Container No. 11

12) Mass of container + Wet soil 62.48

13) Mass of container + dry soil 57.76

14) Mass of container 21.43

15) Mass of dry soil 36.33
