Laboratory of rheological and workability testing

Department of materials and structures

Characterization of rheological properties and workability:
• standard consistence test of cement paste joined with determination of setting times by means of Vicat apparatus;
• soundness test by means of Le Chatelier apparatus;
• determination of consistence of fresh mortar (by flow table) according to Hägermann, slump table based on Graf, L-box for the flowability, Marsh funnel and V-funnel for viscosity;
• evaluation of shrinkage by low channel for grout, screed, and mortar;
• determination of shear stress by rotary rheometer;
• ultrasonic measuring system for the measurement of setting processes;
• air entrainment meter;
• determination of the self-compacting concrete sedimentation behaviour by washout test.
