Addition Rates
WRDA PA can be dosed at between 400 and 1,500mL / 100kg of total cementitious material. The higher addition rates will increase water reduction and acceleration, however admixture performance can depend on concrete components, job conditions, and desired performance characteristics.
To assist you in obtaining optimum performance from your admixtures from GCP Applied Technologies, we can offer comprehensive advice and site assistance service.
Overdosing of WRDA PA will produce and increase concrete workability, air content and decrease setting time. The set acceleration effect will vary dependent on ambient temperatures, cement used, and the amount of overdose. However, provided correct curing procedures are followed, ultimate concrete strengths may be higher than a corresponding mix or standard admixture-dosed concrete.
