The Uniframe-Mini machine is a fully automatic unit specifically designed for transverse deformation testing of tile adhesives and grouts. During operation, the machine measures the transverse deformation of a tile adhesive or grout strip specimen with prescribed dimensions (3mm thickness), whilst subjecting it to a 3-point bending load which is gradually increased in such a way that the transverse deformation is constant at 2mm/min. The test is completed when failure occurs. Great attention has been given to the machine design, as shown by the high-stiffness frame which allows wide access to the test area, the robust loading anvil and supports, the easily readable touchscreen graphic display mounted at head-height and oriented towards the user at a comfortable angle, the appropriately positioned connection ports on the rear of the machine and the compact and ergonomic overall construction. The transverse deformation rate is automatically controlled by an advanced closed-loop controller based on a customized algorithm.
