Very small bending specimens made of ultra-light foamed concrete (also "mineralized foam") can only be tested insufficiently accurately on a hydraulic bending testing machine. Breaking forces of less than 10 N are too demanding for conventional hydraulic control.
Dr.-Ing. Albrecht Gilka-Bötzow, scientific assistant at the Institute for Materials in Civil Engineering (WiB) and member of the project team for the construction of the ETA factory at the Technical University of Darmstadt, can now measure even the smallest bending forces on an inspekt table 100 kN from Hegewald and Peschke, position-controlled, and determine small deflections with a probe attached to the specimen. The testing machine was purchased this year by the Institute for Materials in Civil Engineering and, in addition to a scaled CMOD test based on DIN EN 14651, is also suitable for demanding tensile and compression tests on innovative concrete materials such as mineralised foams.
The scope of delivery included extensive accessories for compression and bending tests as well as the LabMaster materials testing software.
