        摘要:以提高石膏耐水性及轻质化为目的,以水胶比、EPS掺量、复合硅酸盐水泥掺量为影响因素设计正交试验,研究3个因素共同作用下石膏吸水率、表观密度、抗压强度、抗折强度、软化系数的变化趋势。试验结果表明:复合硅酸盐水泥掺量对石膏的耐水性影响显著,EPS掺量对石膏的轻质性影响显著;当水胶比为0.7、EPS掺量为1.6%、复合硅酸盐水泥掺量为18%时,可以制备出轻质耐水的石膏墙体材料。

        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.
