Question

Students in the materials class prepared three mortar mixes with water to

cement ratios of 0.50, 0.55, and 0.60. Three 50-mm mortar cubes were pre-
pared for each mix. The cubes were cured for 7 days and then tested for com-
pressive strength. The test results were as shown in Table P6.16.Determine the following:
a. The compressive strength of each cube.
b. The average compressive strength for each mix.
c. Plot the average compressive strength versus w/c ratios for all mixes.
d. Comment on the effect of increasing w/c ratio on the compressive strength
of the cubes.
