摘要
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。
With single graded industrial by - produced gypsum as basic material, poly carboxylic acid water - reducer, melamine super- plasticizer, hydroxypropyl methyl cellulose, protein retarder, organic acids, alkaline phosphate retarders on expansion, 30min setting time fluidity loss, the main properties of bending strength, compressive strength and impact of single - component β gypsum - based self - level- ing mortar were researched. Mixed by reasonable packing, then gypsum - based self - leveling mortar was prepared according to the building materials industry standard code ＂gypsum- based self- leveling mortar＂ JCT 1023 -2007.
