无机掺合料改善脱硫建筑石膏耐水性试验研究

Research on improvement of water resistance of desulphurization building gypsum with inorganic admixture

通过测试强度、软化系数、吸水率指标,考察了无机掺合料水泥、粉煤灰、矿渣粉、生石灰、硅钙渣对脱硫建筑石膏耐水性的影响,结果表明,掺加碱性掺合料均能提高脱硫建筑石膏耐水性,复掺效果更好。

According to the lab research, the study identifies the strength, softening coefficients, and water absorption index, considers the influence of the inorganic admixture, the fly ash, the slag powder, the quick lime, and the silicium-calcium slag, on the water resistance of desul- phurization building gypsum, and proves by the result that the mixture of the alkaline mixture can improve the water resistance of desulphurization building gypsum, and its compound addition has better effect.
