Determine the in-situ dry unit weight, Civil Engineering

Assignment Help:

Q. The following observations were recorded in a Field density determination by sand-replacement method:

Volume of Calibrating can = 1000 cm3

Weight of empty can = 10 N

Weight of can + sand = 26.6 N

Weight of sand required to fill the excavated hole = 8.28 N

Weight of excavated soil = 9.90 N

In-situ water content = 10%

Determine the in-situ dry unit weight and the in-situ dry unit weight.
