| 摘要 |
The invention relates to a dry mixture that comprises Portland limestone cement, aluminous cement (alumina cement) and calcium sulfate combined with iron sulfate and/or aluminium sulfate and that is especially suitable for filler, plaster floor or flooring screed compounds. The filler, plaster floor or flooring screed compounds so obtained are characterized by an especially smooth surface having a substantially reduced roughness compared to conventional filler, plaster floor or flooring screed compounds after application and setting or hardening, thereby eliminating the need for rough-grinding the smoothed or applied surface and substantially facilitating adhesion to a top layer. |
