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.
