        Abstract:In order to improve the water resistance and lightness of gypsum,with water-binder ratio,EPS content,and composite Portland cement content as influencing factors,an orthogonal test was designed to study the change trends of water absorption rate,apparent density,compressive strength,flexural strength,and softening factor under the combined function of three factors. The test results show that the amount of composite Portland cement has a significant effect on the water resistance of gypsum,and the amount of EPS has a significant effect on the lightness of gypsum. When the preparation process is 0.7 of water-binder ratio,1.6% of the EPS content,and 18% of the composite Portland cement content,a lightweight and water-resistant gypsum wall material can be prepared.
