新鲜胶结尾砂充填料浆的流动性取决于它的流变特性,所以理解新鲜料浆的流变性具有重要的意义。此外,料浆的流变性又与料浆中所发生的水泥水化反应进程和温度的发展变化相关。基于此原因,建立数值模型以分析和预测在水化反应和温度耦合作用下充填料浆流变特性的演化规律。在实验室通过试验研究了料浆的流变行为,并将试验结果与模拟结果进行对比来验证模型的有效性。在不同的条件(料浆的初始温度、灰砂比、水灰比)下,利用所建立的模型对水化反应和温度耦合效应下的料浆流变规律进行模拟研究。研究结果有助于更好地理解胶结尾砂充填料浆的流变性。 The fluidity of fresh cementitious tailings filler slurries depends on their rheological properties, so understanding the rheology of fresh slurries is of great importance. In addition, the rheology of the slurry is related to the development of the cement hydration reaction process and temperature in the slurry. For this reason, a numerical model was established to analyze and predict the evolution of the slurry rheological behavior under the coupling of hydration and temperature. The rheological behavior of the slurry was studied experimentally in the laboratory, and the experimental results were compared with the simulation results to verify the validity of the model. Under different conditions (initial temperature of slurry, lime-sand ratio, water-cement ratio), the model was used to simulate the rheological behavior of slurry under the coupling effect of hydration and temperature. The results contribute to a better understanding of the rheology of cementitious tailings filled slurries.
