Textbook Question
Chapter 6, Problem 6.16QP
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 prepared for each mix. The cubes were cured for 7 days and then tested for compressive 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.
