CAD Instruments offers 2 lab devices for studying the workability of cement pastes, mortars and fresh concrete: MiniSlump MBE450 or MiniSlump MSP. These tests are carried out using molds with conical shapes made of stainless steel or nickel coated steel for better resistance.
Surface measurement is Corian™ manufactured, a hard and non-absorbent surface required for the test but also ensuring perfect planarity.
Stainless steel cone perfectly designedy.
Integrated rule for measurement of spreading
Manual system for lifting
To improve repeatability of the measurement, CAD Instruments has developed MiniSlump MSP where the cone is lifted at constant speed by a pneumatically driven table.
