My CEE 2105 project topic is a portion of my thesis.  I will be studying
the feasibility of using glass as a replecement for sand and cement in
concrete.  I will be comparing green, amber, clear, and a color mixture of
glass.  The sand will be replaced by a mixture of glass that passes the
1/4" sieve and remains on the #100 sieve.  The cement will be replaced
with two different sizes.  The first is glass passing the #100 sieve and
remaining on the #200 sieve.  The second is glass passing the #200 sieve.
Each size will be tested at three replacement percentages: 5%, 7.5%, and
10%.  The concrete test cylinders (6" long and 3" diameter) will be tested
for compression strength after 3, 7, 21, 28, 56, 90, and 120 days and will
be compared to a control mixture that does not contain any glass.  A total
of 370 test cylinders will need to be made.
