针对不同组成的自密实混凝土,在参数研究范围内,就混凝土组成对新拌混凝土性能的影响情况进行了研究。借助于胶凝材料层厚度的模型参数不仅可以得到标准粘度测定的特征值,而且可以描述两个流变学参数,即屈服极限和塑性粘度。通过对结果的比较,认为可以采用透过间隙性试验的特征值对屈服极限和塑性粘度进行估算。
According to the different composition of self-compacting concrete, the influence of concrete composition on the properties of fresh concrete was studied in the range of parameter study. With the help of model parameters for the thickness of the cementitious layer, not only can the eigenvalue of the standard viscosity determination be obtained, but also two rheological parameters, namely the yield point and the plastic viscosity, can be described. Through the comparison of the results, it is considered that the yield limit and the plastic viscosity can be estimated by using the eigenvalues of the interstitial test.
