Abstract:

本发明公开了一种高贝利特硫铝酸盐水泥专用缓凝剂,是由下列物质组合而成:梳状聚羧酸盐聚合物(重均分子量30000~50000)、柠檬酸、β‑环糊精、氨基三亚甲基膦酸和硼砂。本发明中所有缓凝组分在水泥中掺量均在0.05%~1.00%范围内,当聚羧酸减水剂为0.15%,柠檬酸为1.00%,β‑环糊精为1.00%,氨基三亚甲基膦酸为0.25%,硼砂为0.20%时,这种专用缓凝剂对高贝利特硫铝酸盐水泥的缓凝效果最显著。这种适用于高贝利特硫铝酸盐水泥的专用缓凝剂不仅可以延长该种水泥凝结时间,还能改善高贝利特硫铝酸盐水泥浆体流动度和中后期胶砂强度。本发明无毒无味、环境友好产品,且便于运输储存,具有良好的应用前景。
