Study on the Preparation and Properties of Desulfurization Gypsum-Based Self-Leveling Material

Abstract:

In this paper self-leveling floor material with flue gas desulfurization (FGD) gypsum was studied. Gypsum-based self-leveling materials was prepared with desulfurization gypsum as binder and added fly ashadmixture Aadmixture B and four kinds of water reducing agents. The result indicated that HC multi-carboxylic acid based super plasticizer demonstrates excellent workability and better compatibility with gypsum, when its content was 1.0%, the fluidity of slurry met the demands of 145mm±5mm. Adding re-dispersible polymer powder to enhance the strength of desulfurization gypsum, the results showed that when its content was 3%, the adhesive strength of sample was increased to 1.21MPa that could meet the performance requirements of self-leveling floor material.
