Water-Cement Ratio in Concrete - a detailed description

The water-cement ratio is the weight of water to the weight of cement in the concrete mix. The water-cement ratio directly influences the strength of concrete. To achieve a higher-strength of concrete, a lower Water Cement ratio is used, along with a plasticizer or superplasticizer to increase workability.
