Use of Water Reducers Retarders and Superplasticizers. Introduction. Many important characteristics of concrete are influenced by the ratio (by weight) of water to cementitious materials (w/cm) used in the mixture. By reducing the amount of water the cement paste will have higher density which results in higher paste quality.
