The compaction factor test is recommended for concrete mixes having the degree of workability - 'very low' (such as pavement quality concrete) And the value of compacting factor should be in the range if 0.75 to 0.80. Therefore for cement having low water cement ratio, workability is determined by compaction factor test.

Workability of Concrete - Types and Effects on Concrete ...

The increase in water cement ratio indicates increase in workability of concrete. Thus, the strength of concrete inversely proportional to the workability of concrete. The reason for this relation is that water from the concrete dries up and leaves voids when setting of concrete occurs. The more the water is, the more will be the number of voids. Thus, increase in number of voids decreases the ...

what is water cement ratio for concrete

12/09/2021  The quantity of water divided by the quantity of cement (both measured in kilograms) gives the water - cement ratio. A low water to cement ratio leads to high strength but low work ability. A high water to cement ratio produces a low strength concrete but good work ability. A common shortcoming in concrete works is that too much water is added as it is then easier to spread and

If the water-cement ratio is small, it indicates high amount cement which is helpful for good strength. But the small water-cement ratio is responsible for lower workability. If proper compaction cannot be achieved, concrete will not be enough strong as desired. On the other hand, if the water-cement ratio is increased, workability and compaction problem will be solved but there may occur some ...

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. Cementitious ...
