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 .
