Use of Water Reducers, Retarders, and Superplasticizer

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.

2.2.1 The role of retarders Setting and W/P ratio can be controlled, to a certain degree, by additives. It is state of the art to combine BMA with PlastRetard L. Every retarder acts a bit differently in regard to the setting kinetics as shown in figure 6. These differences are crucial in plasterboard production as will be shown below.
