Hi,

This problem deals with the Sand Cone Test used to determine the density of the compacted soil.

the volume of the standard Proctor mold = 1/30 cubic feet

Mass of the sand drained to fill the mold = 3.30 lbs

Mass of the sand to fill the cone = 0.53 lbs

Mass of the soil dug from the hole = 8.11 lbs (and have water content w = 11.11%)

Mass of jug + Sand + Cone before used to fill the hole = 10.20 lbs

Mass of jug+ Sand cone after used = 3.20 lbs

Determine: (A) The density of the Ottawa Sand(pcf)

(B) The volume of the cone (cubic feet)

(C) The volume of the hole dug + Cone (Cubic ft)

(D) The volume of the hole dug

(E) The dry density of the compacted soil

Thanks!

This problem deals with the Sand Cone Test used to determine the density of the compacted soil.

**Problem:**A sand cone density test was conducted on a soil compaction at a land development project. It has the following data:the volume of the standard Proctor mold = 1/30 cubic feet

Mass of the sand drained to fill the mold = 3.30 lbs

Mass of the sand to fill the cone = 0.53 lbs

Mass of the soil dug from the hole = 8.11 lbs (and have water content w = 11.11%)

Mass of jug + Sand + Cone before used to fill the hole = 10.20 lbs

Mass of jug+ Sand cone after used = 3.20 lbs

Determine: (A) The density of the Ottawa Sand(pcf)

(B) The volume of the cone (cubic feet)

(C) The volume of the hole dug + Cone (Cubic ft)

(D) The volume of the hole dug

(E) The dry density of the compacted soil

**Solution (see image):**Thanks!
