Result of compressing load application tests made by TUM Technical University Munich

The demand of the load capacity by a hollow- space- floor are comming up by the expexted surface and point load.

Extract of the compressive load application test of HARBOLA- hollow- space- floor

point load 4 x 4 cm 17,47 kN 19,96 kN 36,47 kN 51,94 kN
stripe load 6 cm not tested not tested 105,80 kN 120,00 kN
stripe load 10 cm not tested not tested 51,59 kN 69,87 kN
surface load 48,8 x 48,8 cm simillar to ZE 20 simillar to ZE 30 1101,00 kN 1566,00 kN
1 mug filled 341,30 kN 429,20 kN 285,20 kN 422,20 kN

  ZE = cement screed,   AE = anhydride screed

The load capacity of the HARBOLA hollow- space- floor at final state (covered by screed) is only depending of the compression- and bending tensile strength of the screed and the hight. In testing case= screed hight 5 cm.
