What is Concrete Mix Design for CIV 321 about?

Here are the steps to solve this problem: 1. Select a water-cement ratio based on the exposure condition (frequent wetting by fresh water). From Table 9-2, use a ratio of 0.45-0.50. Select 0.45. 2. Estimate the cement content based on the required compressive strength of 28 MPa from Table 9-7. Use 300 kg/m3. 3. Calculate the water content based on the water-cement ratio of 0.45 and cement content of 300 kg/m3. Water content = 0.45 * 300 = 135 kg/m3. 4. Use the absolute volume method to calculate volu
