Water-cement ratio is :a)The ratio of volume of water mixed in concre...
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.

Water-Cement Ratio in Concrete
Water-cement ratio is an important factor in concrete mix design. It is the ratio of the volume of water to the volume of cement used in the mixture. This ratio determines the strength, workability, and durability of concrete.
Formula for Water-Cement Ratio
The water-cement ratio is calculated using the following formula:
Water-cement ratio = Volume of water ÷ Volume of cement
Factors Affecting Water-Cement Ratio
The water-cement ratio is affected by several factors, such as:
- Strength requirement of concrete
- Workability of concrete
- Durability of concrete
- Type of cement used
- Aggregate size and shape
- Temperature and humidity conditions
- Admixtures used
Importance of Water-Cement Ratio
The water-cement ratio is an important factor in determining the strength and durability of concrete. A low water-cement ratio means that the concrete will have higher strength and durability, while a high water-cement ratio means that the concrete will have lower strength and durability.
Effects of High Water-Cement Ratio
When the water-cement ratio is high, the following effects may occur:
- Reduced strength and durability of concrete
- Increased shrinkage and cracking of concrete
- Increased permeability and susceptibility to water damage
- Reduced resistance to freeze-thaw cycles and chemical attack
Effects of Low Water-Cement Ratio
When the water-cement ratio is low, the following effects may occur:
- Reduced workability of concrete
- Difficulty in placing and compacting concrete
- Increased risk of segregation and bleeding
- Increased heat of hydration and potential for thermal cracking
Conclusion
In conclusion, the water-cement ratio is the ratio of the volume of water to the volume of cement used in the mixture. It is an important factor in determining the strength, workability, and durability of concrete. A low water-cement ratio means that the concrete will have higher strength and durability, while a high water-cement ratio means that the concrete will have lower strength and durability.
