Concrete admixture is added to the concrete after addition of desired amount of water during mixing of concrete in mixer.
Generally dosed in the range of 0.5 to 1.0% by weight of cementitious materials. But go for trial mix for finalizing the dosages.
Higher dosages are acceptable with prior testing and confirmation of the desired performance with specific materials being used.
CONCET MR PRO should be added to the initial batch water when possible. It should not come in contact with dry cement or other admixtures until mixed thoroughly with the concrete batch.
Field testing is strongly recommended to optimize dose range and performance expectations with local materials. CONCET MR PRO is compatible with most admixtures including air-entraining agents, accelerators, most water-reducers, retarders, shrinkage reducers, corrosion inhibitors, viscosity modifiers, and microsilica; however,each material should be added to the concrete separately.
