Students in the materials class prepared three mortar míxes 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.

Q1) Define the C-S-H phase of cement paste. Q2) Discuss the effect of water-cement ratio on the quality of hardened concrete. Explain why this effect happens. Q3) In order to evaluate the suitability of nonpotable water available at the job site for mixing concrete, six standard mortar cubes were made using that water and six others using potable water. The cubes were tested for compressive strength after 7 days of curing and produced the loads to failure (in pounds) shown in Table: Cubes Made with Nonpotable Water Cubes Made with Potable Water 14,530 16,530 16,820 17,920 15,690 18,820 16,720 15,820 14,160 16,100 15,870 14,380 Based on these results only, would you accept that water for mixing concrete according to ASTM C94?
