钢渣微粉改性磷石膏试验研究

Experimental Study on Modified Phosphogypsum with Steel Slag Powder

利用钢渣微粉中的活性石灰中和磷石膏的酸性,改善磷石膏的颗粒级配,降低建筑石膏的标准稠度用水量,进而提高强度。实验表明钢渣微粉20%掺量对磷石膏增强幅度超过30%。

The active lime in the steel slag powder neutralizes the acidity of the phosphogypsum,improves the particle gradation of the phosphogypsum,reduces the water consumption of the standard consistency of the building gypsum,and further increases the strength.Experiments show that the 20%blending amount of steel slag powder enhances the phosphogypsum by more than 30%.
