Research on a New Kind of Waterproof Agent for Desulphurization Gypsum Materials Block

Abstract:

The paper studied a compound desulphurization gypsum waterproof agent, which could modify the water-resistance performance of gypsum products on the basis of their microstructural properties. The waterproof mechanics were the synthesis results of superficial hydrophobic of hydrophobic emulsion, hindrance water of film forming matter and reducing the porosity in materials. The experiment results showed that the water-absorption rate of gypsum hardened body can be reduced to 3.5% and that the compressive strength reserve rate was 89.7% after 24h.
