The results of a laboratory experiment to
evaluate the effects of a plasticizer are
shown.
a. Calculate the water/cement in each of the
three cases.
b. Choose an appropriate case - that by
using water reducer, how can we increase
the compressive strength of concrete
without changing workability? (Refer to the
appropriate case in the table.)
c. Choose an appropriate case - that by
using water reducer, how can we improve
workability without changing the
compressive strength? (Refer to the
appropriate case in the table.)
d. Choose an appropriate case - that by
using water reducer, how can we reduce
cost without changing workability or
strength? (Refer to the appropriate case in
the table.)
