Worked Example: 03

It is required to prepare a compacted cylindrical specimen of 50 mm dia and 90 mm length from an oven dry soil. The specimen is required to have water content of 15% and percent air voids of 20%. Taking G=2.7, determine the weight of soil and weight of water, required for preparation of the above specimen.

TIP: Total volume of the V=Vs+Vw+Va. We will use this relationship to determine weight of of solids then using total weight equation, we can determine weight of water.
