Conclusion The experiment yielded the following conclusions: 1. There is a direct non-linear relationship between the water cement ratio and the slump. 2. Equation 1 can be used to determine the water cement ratio required to produce the desired slump. It should be noted that Equation 1 has only been validated for the experimental mix design used in this experiment.

Water/Cement Ratio - an overview ScienceDirect Topics

The ACI method bases the water–cement ratio selection on desired compressive strength and then calculates the required cement content based on the selected water–cement ratio. Table 5.17 is a general estimate of 28-day compressive strength versus water–cement ratio (or water-cementitious ratio). Values in this table tend to be conservative.
