Effect of Water to Cement Ratio on Concrete

The aim of this experiment was to establish the effects of water to cement ratio on the fresh properties of concrete (workability), and its effect on the hardened properties of concrete (strength). Furthermore to increase the understanding in making a concrete mixture and working out the water content that needs to be added to the mixtures.

Water/Cement Ratio - an overview ScienceDirect Topics

The water-cement ratio of the tested standard mix proportion may be not appropriate and the strength of concrete may not accord with requirements, so the concrete strength should be rechecked. Three different mixture ratios will be adopted in rechecking. One is the standard ratio, and the other two are the ratios whose water-cement ratios are increased and reduced by 0.05 respectively.
