The main component of the efficient anti-segregation agent is a macromolecule microbial polymer. It shows good stability, excellent resistance to segregation, water retention and thicken effect and unique rheological properties. It can effectively prevent the mortar and concrete bleeding and segregation, even more could overcome the affect on strength introduced by traditional anti-segregation agents or thickeners. So it is particularly suitable for high-end building products such as grout, self-leveling mortar and self-compacting concrete, etc. Compared with traditional thickeners and anti-segregation agents, DR-1 also resolve the problems of measure and dispersion, stick knives, air bubbles and other issues.
