中文摘要：

基于Matlab平台,同时考虑聚羧酸系高性能减水剂的饱和掺量点、水泥浆体的初始Marsh时间或流动度、经时损失率、凝结时间和泌水率的影响,将掺有聚羧酸系高性能减水剂受检水泥与基准水泥相比较的各因子作为评判其相容性的指标,建立相应的隶属度函数,运用模糊数学评判方法,打破基准水泥的局限,对聚羧酸系高性能减水剂与水泥的相容性作出较为全面和准确的综合性评价。试验结果分析表明,掺入评价结果为优的同一聚羧酸系高性能减水剂预拌混凝土性能与其水泥浆体一致,相关性较好。研究对于绿色高性能减水剂混凝土的配制具有指导意义。

英文摘要：

In this paper, the initial marsh-time or fluidity （MF）, loss rate of fluidity as time （FL）, saturation point （SP）, setting time （ST）, and bleeding rate are considered simultaneously to evaluate the compatibility between a polycarboxylate high-performance water-reducing （HP- WR） agent and cement. The comparisons of these parameters between tested concrete and refer- ence cement are conducted, and the corresponding membership functions are established. Then, the fuzzy mathematical evaluation method based on Matlab is used, and the limitation of refer- ence cement is broken, resulting in a more comprehensive and accurate evaluation. Both the premixed concrete and the cement paste, which use the same polycarboxylate HPWR agent, are evaluated as ＂the best＂ by the method proposed in this paper, and the consistency is acquiredaccording to the performance experiment. Results also show that they have good correlation. The research findings can serve as guidelines in the preparation of green concrete made of HPWR agents.
