ADDITIVE FOR CONSTRUCTION MATERIAL MIXTURES COMPRISING FLOW AGENTS.

摘要

The invention relates to a cationic copolymer and to the use thereof as an additive for construction material systems, in particular based on calcium sulfate. The copolymers according to the invention bring about an accelerated bond breakdown behavior in gypsums both comprising clay and comprising no clay, and allow unlimited water reduction capability of dispersing agents used simultaneously with the copolymers. The clay components present in the gypsum system are masked by the cationic copolymer, so that the construction material mixture comprises properties of a construction material mixture comprising no clay. The copolymers are thereby used as a formulation, and together with inhibitors.
