Hebel Autoclaved Aerated Concrete

Hebel is a lightweight autoclaved aerated concrete (AAC). It is completely cured, inert and stable form of calcium silicate hydrate. It is a structural material, approximately one quarter the weight of conventional concrete, composed of minute cells which give the material lightweight, high thermal insulation, fire resistant and sound insulation properties. It is available as blocks, panels and precast reinforced units, i.e. floors, roofs and lintels.

Building with Hebel is two to ten times faster than conventional building

Agrément South Africa approved, AAC as a building material has gained a considerable share of the international construction market since its inception in Sweden in the 1920s.  The following attributes, amongst others, is why it has become the preferred choice internationally for more than 80 years:

Structural properties

  • Rated for a 2 storey building when built with blocks.  Size: 600 x 250 x 110 / 150 mm
  • Rated for a 4 storey building when built with panels: 5Mpa compressive strength at a density of 600 kg/m3.  Size:  600 mm wide up to 3 m high. Thickness: 100 or 150 mm.

Fire resistance – non combustible

  • A 150 mm thick Hebel wall can withstand direct fire exposure for up to 6 hours.
  • A 100 mm thick Hebel wall can withstand direct fire exposure for up to 4 hours

Thermal Insulation

  • 5 times that of brick of the same thickness

Speed and ease of construction

  • 2 – 10 times faster than conventional building
