Contribution to the Concrete Strength versus Water

The first rarely mentioned fundamental assumptions for the strength versus water-cement ratio relationship are discussed, namely, that: (a) the strength of structural concrete is controlled by the strength of the cement paste in it; (b) the strength of a cement paste depends strongly on the porosity in it; and (c) the porosity (capillary) is a function of the water-cement ratio.

Analysis of Concrete Strength Versus Water-Cement Ratio

1990-9-1  Analysis of a variety of experimental data shows that this is not absolutely true. For instance, if two comparable concretes have the same water-cement ratio, the strength of the concrete with higher cement content is lower. This observation is reflected by presenting new formulas (mathematic models).

Water–cement ratio - Wikipedia

2022-7-11  The water–cement ratio is the ratio of the weight of water to the weight of cement used in a concrete mix. A lower ratio leads to higher strength and durability, but may make the mix difficult to work with and form. Workability can be resolved with the use of plasticizers or super-plasticizers.. Often, the ratio refers to the ratio of water to cementitious materials, w/cm.
