USE OF POLYSULFIDE-FREE PREPARATIONS AS AN ADDITIVE FOR LOAM OR CLAY-BASED CONSTRUCTION MATERIALS

摘要

The use is described of polysulfide-free preparations comprising, based on solids content, from 40 to 99.5% by weight of at least one water-dispersible copolymer and from 0.5 to 10% by weight of at least one alkoxylated ionic or nonionic emulsifier, as additives for construction materials based on loam or clay. The building materials based on loam or clay and comprising the preparation are described, as are the use of the construction materials and a process for treating construction materials with the preparation.
