Please provide complete solution.
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.
6. 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 -
6y 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)
