| Résumé: | Self-Compacting Mortars (SCM) can be regarded as high flowing mortars, which must show both a good fluidity (to fill complex formwork shapes) and sufficient viscosity (to avoid segregation). The characterization and control of fresh properties are proving to be critical for the success of SCM design. Usually, this task is performed through technological tests such as v-funnel and minislump. However, the use of viscometers can successfully perform better access of fresh properties. The objective of the present work is to correlate experimental results of v-funnel and mini-slump tests with viscosity of SCM, measured at different rotational speeds, and with constants a and b calculated from the power-law viscosity model. Linear relationships between both v-funnel and minislump tests and viscosity were demonstrated. Statistical models are also established to highlight the influence of constants a and b on the v-funnel and mini-slump variations. Results indicate the usefulness of established models to better understand the trade-off between constants a and b on fresh properties measured by v-funnel and mini-slump tests |
