Students prepared three mortar mixes in materials lab with water to cement ratios of 0.50, 0.55 and 0.60. Three 50mm mortar cubes were prepared for each mix. The cubes were tested for 7 days compressive strength. The test results are shown in table below: Average Compressive Strength (MPa) Maximum Load Compressive Strength (MPa) Mix No. W/C Ratio Cube No. (kN) 1 0.50 1 75.4 76.1 3. 77.8 0.55 1 70.9 70.7 3 68.8 0.60 62.5 65.8 3 67.6 3.
