摘要

在这项工作中，我们介绍了在水灰比（W/C）分别为0.30、0.36和0.40的新鲜水泥浆体（PC）PC30、PC36和PC40以及在水灰填料比（W/Fc）=0.30和0.348的新鲜石灰石填料浆体（Fc）上获得的实验研究结果，用于使用恒定水头渗透仪测量导水率。使用了不连续的水力传导率测量。对该参数的分析允许获得关于材料在制造的最初几个小时内的流变行为的一些信息。在相同的体积浓度和类似的粒度下，石灰石填料浆体的导水率似乎大于水泥浆体。

Study of Hydraulic Conductivity on Fresh Cement-Based Materials; Laboratory Experiments

We present in this work the results of an experimental study obtained on fresh cement pastes (PC) PC30, PC36 and PC40 with water- to- cement ratio (W/C) of 0.30, 0.36 and 0.40, respectively and on fresh limestone filler pastes (Fc) with water-to-limestone filler ratio (W/Fc) = 0.30 and 0.348 for the measurement of the hydraulic conductivity using the constant head permeameter. Discontinuous measurement of hydraulic conductivity was used. An analysis of this parameter allows some information to be obtained on the rheological behavior of the material in the first hours of its manufacture. It appears that at the same volume concentration and for a comparable particle size, the hydraulic conductivity of limestone filler pastes is greater than that of cement pastes.
