以级配较为单一的工业副产β石膏作为基本材料，研究聚羧酸减水剂、三聚氰胺减水剂、羟丙基甲基纤维素醚、蛋白类缓凝剂、有机酸类缓凝剂、碱性磷酸盐缓凝剂对单组份β石膏基自流平砂浆的扩展度、30min流动度损失、凝结时间、抗折强度、抗压强度等主要性能的影响。以及通过合理填料的复配，进而制备符合建材行业标准《石膏基自流平砂浆》JCT 1023-2007的石膏基自流平砂浆。
以級配較為單一的工業副產β石膏作為基本材料，研究聚羧痠減水劑、三聚氰胺減水劑、羥丙基甲基纖維素醚、蛋白類緩凝劑、有機痠類緩凝劑、堿性燐痠鹽緩凝劑對單組份β石膏基自流平砂漿的擴展度、30min流動度損失、凝結時間、抗摺彊度、抗壓彊度等主要性能的影響。以及通過閤理填料的複配，進而製備符閤建材行業標準《石膏基自流平砂漿》JCT 1023-2007的石膏基自流平砂漿。
