The effects of four sand contents on the compressive, flexural and splittingtensile strength of cement mortars were evaluated. Moreover, we experimentally investigated the pore structure of cement mortar brought about by changing the sand content and water/cement ratio. 
WatertoCement Ratio and Aggregate Moisture Corrections
Watertocement ratio The maximum watertocement ratio may be established by the customer or authority having jurisdiction based on anticipated exposure conditions. The target w/c ratio can also be selected from available data on the actual materials that will be used. 
Effects of cement type, water/cement ratio and cement ...
Residual strength ratio after sea water effect at 250 kg/m3 cement increase in W/C ratio from 0.43 to 0.53 resulted in slight content. increase in strength. This is probably due to the workability problems at a W/C ratio of 0.43. 
What is the effect of water to cement ratio on the ...
Yes, the most important factor that affects the strength of cement concrete is the water to cement (W/C) ratio. The lower the W/C ratio means the higher would be the strength of cement concrete. 
Effect of Cement Content and Size of Coarse Aggregate on ...

What is the effect in concrete when water cement ratio ...
When water cement ratio is increased the amount of water with a constant cement content in increased. At the end of curing period, by the time the concrete comes into use the water supplied during curing, mixing (of concrete) need to be evaporated (we expect the concrete … 
Cement Content and Watercement Ratio on  scribd.com
This paper investigates the effects of cement content and water/cement ratio on workable fresh concrete properties with slump changing between 90 to 110 mm, and determines the relations among fresh concrete properties such as slump, compacting factor, VeBe, unit weight and setting times of mortar with temperature history. 
Water–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 to work with and form. Workability can be resolved with the use of plasticizers or superplasticizers. 
Effect of metallic aggregate and cement content on ...

The water/cement ratio was kept constant at 0?40 to evaluate the effects of haematite and cement content. Slump tests were conducted to evaluate ... Increasing both cement and haematite content has substantial effects on the strength of 
Effect of Watertocement Ratio on Concrete  Civil ...
Moreover, it is well known that the strength of concrete is affected by the w/c ratio. In the next equation (Feret formula), decreasing w/c gives concrete with higher strength. where k is a constant depending on the type of cement. Feret formula clearly shows the negative effects of water content on the compressive strength of the concrete.

ing from an increase in watercement ratio from 0.4 to 0.6 is about 11% for Type I cement. The effect is minimal for moderate and lowheat cements.(4) The watercement ratio effect is minor compared to the effect of cement content. However, a lower watercement ratio in concrete achieved by increasing the cement content results in

The water cement ratio is the ratio of the weight of water to the weight of cement used in a concrete mix and has an important influence on the quality of concrete produced. A lower watercement ratio leads to higher strength and durability, but may make the mix more difficult to place.

Shrinkage in Concrete, Definition, Types, and Factors ...
So, the more the concrete bleeds, the greater the plastic shrinkage should be. Plastic shrinkage is proportional to cement content and, therefore, inversely proportional to the w/c ratio. Concrete shrinkage of this type manifests itself soon after the concrete is placed in the forms while the concrete is still in the plastic state. 
Creep and shrinkage of concrete  Wikipedia
Creep and shrinkage of concrete are two physical properties of concrete. The creep of concrete, which originates from the calcium silicate hydrates (CSH) in the hardened Portland cement paste (which is the binder of mineral aggregates), is fundamentally different … 
How the W/C Affects Concrete Strength Concrete ...
Watercement ratio is therefore a measure of the void volume relative to the solid volume in hardened cement paste, and its strength goes up as the void volume goes down. So, the lower the w/c, the lower is the void volume/solid volume, and the stronger the hardened cement paste.
