设计不同配合比脱硫石膏-水泥用量组成砂浆胶凝材料，通过加入外加剂改良砂浆性能，测定砂浆28 d抗压强度。研究结果表明，脱硫石膏掺量增加会降低砂浆保水性，砂浆强度随水泥用量增加呈线性增长，随脱硫石膏掺量增加呈线性降低。拟合出此砌筑砂浆的配合比计算公式。

Design the slurry cementing material with different amount of gypsum and cement.By adding admixtures change the perfor-mance of mortar,28 d compressive strength of the mortar was tested.The results showed that desulfurization gypsum dosage increased lead to reduce water retention.Mortar strength with cement dosage increase linearly growth,along with the desulfurization gypsum dosage in-crease linearly reduce.Given mix proportion formula of the mortar in two kind of admixture.
