Details of the concrete mix proportions are presented in Table 1, in which CC denotes the control concrete mixed with tap water, F represents a concrete containing fly ash as a cement replacement at 20 wt%, S denotes a concrete mixed with superplasticizer at 1 wt%, and W represents concrete prepared using sludge water without fly ash or 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.

11/20/2019· Accelerating concrete admixtures are used to increase the rate of concrete strength development or to reduce concrete setting time. Calcium chloride could be named as the most common accelerator component; however, it could promote corrosion activity of steel reinforcement.Nonetheless, concrete best practices, such as proper consolidation, adequate cover and proper concrete mix …
