Weight is defined as the quantity of matter contained in a body. Weight can also be defined as the force acting on a body due to gravity. Mathematically, weight can be defined as-

Question

Subject is soil Mechanics

The results from a standard Proctor compaction test (ASTM D-698) are given below.
The specific gravity of the soil solids is 2.72.
(A) Pot the corresponding compaction curve and determine the maximum dry unit
weight of compaction and the optimum moisture content. (Report results in the
same tabulated fashion as shown in your notes.) You are required to use MS Excel
software to plot your data points and the best fitting compaction curve.
(B) Plot the 60%, 70%, 80%, 90%, and 100% (zero-air-void) saturation curves against the
same compaction curve from part A. (Report results in the same tabulated fashion
as shown in your notes, including all the "dummy" values of either moisture content
or dry unit weight.) You are also required to use MS Excel software to plot these
curves.
(C) Determine the void ratio and the degree of saturation of the compacted soil at its
optimum moisture content. (Show all pertinent volume-weight relationships and
calculations.)
