The resistance of a (building) material to deformation due to compressing forces, which depends on the density and structure of the material. The compressive strength of the different building materials varies over a wide range.
Sign: Rv
Unit of measure: N/mm2 → MPa (1000 kPa)
For some thermal insulation materials, a significant compressive strength cannot be determined because they are compressed (already) under a relatively low load and are therefore characterised by a compressive strength for a significant compression (short-term loads; 10 % long-term load; 2 % ).
