APPLICATION
MasterRheobuild 623 is a ready-to-use liquid which is dispensed into the concrete together with the mixing water. The plasticising effect and water reduction are higher if the admixture is added to the damp concrete after 50 to 70% of the mixing water has been added. The addition of MasterRheobuild 623 to dry aggregate or cement is not recommended. Automatic dispensers are available.
