Water / Cement Ratio The relation between water cement ratio and strength of concrete is shown in the plot as shown below: The higher the water/cement ratio, the greater the initial spacing between the cement grains and the greater the volume of residual voids not filled by hydration products There is one thing missing on the graphWater–cement ratio - Wikipedia,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 toEffects of Water-Cement Ratios on the Compressive Strength ,The compression strength of concrete is usually determined by performing compression test on standard sizes of concrete blocks or cylinders The strength of concrete is affected partly by the relative proportion of cement and of the fine and coarse aggregates but the water-cement ratio is

Relation Between Compressive and Tensile Strength of Concrete

How the Water-Cement Ratio Affects Concrete Strength

The authors investigate whether the influence of the water-cement ratio on strength arises simply from the fact that a part of the mixing water produces voids t How the Water-Cement Ratio Affects Concrete Strength Author(s): In this connection, it is useful to look into the relation between the strength of mortar and of concrete, both AN INVESTIGATION INTO THE RELATION BETWEEN THE,Itis generally known that the strength of concrete made from given materials depends upon the properties of these materials The water-cement ratio and the amount of air in the hardened concrete have in particular great influence on the strength (5:216)What are the Factors Affecting Workability of Concrete?,Water/Cement Ratio or Water Content of Concrete Higher water/cement ratio is generally used for manual concrete mixing to make the mixing process easier For machine mixing, the water/cement ratio can be reduced These generalised method of using water
