Original Abstract

In the present paper, the well-known wedge splitting test is applied on specimens made from foam concrete. In the case of this material the whole test specimens cannot be made from foam concrete but the rectangular groove, needed for the load transmission pieces, has to be made of stiffer material (typically marble). K-calibration (B1) and T-stress (B2) calibration curves for such specimens are introduced. The objective was to compare and discuss the calibration curves for the homogeneous case, the case with marble parts and the case with marble parts considering the glued marble/foam concrete interface.
