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 - 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 with out changing workability or strength?
