REDBRAWN 671 differentiated from conventional super plasticizers in that it is based on a unique carboxylic ether polymer with long lateral chains. This greatly improves cement dispersion. At the start of the mixing process an electrostatic dispersion occurs but the cement particle’s capacity to separate and disperse. This mechanism considerably reduces the water demand in flow able concrete. REDBRAWN 671 combines properties of water reduction and workability retention. It allows the production of high performance concrete and/or concrete with high workability. It is a strong super- plasticizer allowing production of consistent concrete properties around the required dosage.
