【摘要】 测试了不同胶凝体系低水胶比水泥基复合材料的流变学性能、绘制了流变曲线,分析其适用的流变模型。结果表明,低水胶比水泥基复合材料表现出典型的胀流型流体特性,Bingham模型不能准确表征低水胶比水泥基复合材料的流变特性,采用Herschel-Bulkley模型更为适宜。更多还原

【Abstract】 Flow curves of cement-based materials with different cementitious compositions at low water-binder ratio are tested by a rheometer, and the suitability of some fluid models is analyzed. The results show that cement-based material at low water-binder ratio has the characteristics of dilatant fluid. Instead of Bingham model, Herschel-Bulkley model is considered the most appropriate one for analyzing the rheological characteristics of cement-based material with low water-binder ratio.更多还原
