Coupled effect of time and temperature on variations of plastic viscosity of highly flowable mortar

Jean-Yves Petit, Auteur ; Kamal H. Khayat, Auteur ; Eric Wirquin, Auteur |

Dans Cement and concrete research (Vol. 39 N° 3, Mars 2009)

Self-consolidating concrete (SCC) is being increasingly used as construction material for its workability. However, the rheological properties of such concrete, which is made with significant concentration of high-range water-reducing admixture [...]

Effect of limestone filler content and superplasticizer dosage on rheological parameters of highly flowable mortar under light pressure conditions

Jean-Yves Petit, Auteur ; Eric Wirquina, Auteur |

Dans Cement and concrete research (Vol. 40 N° 2 (02 ex.), Fevrier 2010)

The influence of pressure on the yield stress and plastic viscosity of SCC mortars was investigated using an adapted Marsh cone with cylindrical shear paddles. Nine mortars proportioned with various limestone filler content and high-range water-[...]
