稳定水泥浆流变性试验研究

Study on the Stable Cement Paste Rheological Test

对聚合物稳定剂水泥浆和膨润土稳定剂水泥浆进行了流变试验研究,按宾汉流变模型对其流变参数 进行了理论计算;结果表明,聚合物稳定剂水泥浆动切应力较膨润土稳定剂水泥浆低,其可灌性和扩展半径要 优于膨润土稳定剂水泥浆。

The polymer stable-reagent paste and bentonite stable-reagent cement paste have been tested through rheological experiment. According to Binham rheological model, its rheological parameter is calculated . The result shows that the polymer stable-reagent cement paste is lower than bentonite stable-reagent cement paste in act-cut-stress, more superior in grouting capability and expanding radius.
