Water reducing admixtures usually reduce the required water content for a concrete mixture by about 5 to 10 percent Consequently concrete containing a water reducing admixture needs less water to reach a required slump than untreated concrete The treated concrete can have a lower water cement ratioNov 20 32 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 reinforcementNonetheless concrete best practices such as proper consolidation adequate cover and proper concrete mix design
