The development of new empirical apparatuses for evaluation fresh properties of self-consolidating mortar: Theoretical and experimental study

In this study, based on the flow velocity and volume to surface ratio method, new apparatuses were developed to evaluate the fresh properties of SCMO. Mini J-ring, mini U-box, and mini L-box were used to measure passing ability parameters. Mini slump, mini Orimet, new mini V-funnel and mini V-funnel were used to measure filling ability and mini column segregation was used to measure segregation of self-consolidating mortars. The relationships between critical areas of mentioned methods are considered. The Experimental set-up method was used to record the fresh properties. In addition, 27 different mortar mixtures were prepared to verify the test methods. Results show that flow velocity and volume to surface ratio were appropriate criteria to design new apparatuses to measure fresh properties of self-consolidating mortar.
