Aerated concrete - the properties

Autoclaved aerated concrete has a number of advantageous properties, but the negative properties of aerated concrete have very little effect in practice. What makes aerated concrete such a beneficial building material, and which negative properties you should under certain circumstances take into account, therefore reveals this contribution.

Positive properties of aerated concrete

  • weight savings
  • price advantage
  • easy handling
  • uncomplicated processing
  • high thermal insulation capacity
  • Processing of large stones
  • lower mortar consumption
  • lower transport costs
  • less complicated statics

weight savings

Aerated concrete consists of foamed material. The millions of small air bubbles contained in the finished aerated concrete reduce the total weight of the stone. Lower weight of the building materials brings multiple benefits to the construction - for example, in terms of static, transport costs and workability.

price advantage

Unlike bricks, less energy is needed to produce aerated concrete. Because of the lower manufacturing cost of aerated concrete is therefore cheaper.

Easy handling

The low weight and the execution as a level make gas concrete blocks very easy and efficient processable. This aerated concrete is well suited for DIY. For craftsmen, using them saves time.

Uncomplicated processing

Concrete blocks can be processed much less complicated than traditional bricks. There are fewer hand movements needed. This leads to higher efficiency and significant time savings, but also reduces potential sources of error.

High thermal insulation capacity

The high amount of trapped air ensures excellent thermal insulation. In solid constructions made of aerated concrete can usually account for an additional thermal insulation.

Processing of large stones

Because of the lower material weight, even large stones can still be processed well and placed precisely. Large stones offer even better thermal insulation due to the smaller number of joints and at the same time offer further time savings.

Lower mortar consumption

Concrete blocks made of cellular concrete can be walled in a thin bed process. This reduces mortar consumption by almost two-thirds compared to conventional construction.

Lower transport costs

The lower weight of the material also leads to lower transport costs during delivery. Assigned to the entire house construction arises here, together with the lower mortar consumption often unnoticed, but significant cost savings.

Less complicated statics

If a building is made of lighter material, the static load is lower. That can bring some simplification in the construction.

Negative properties of aerated concrete

High water absorption capacity

Aerated concrete absorbs more water than traditional bricks and therefore dries much slower. If it comes to the soaking of the stones during the construction phase longer drying times must be taken into account.

Lower strength

In terms of strength, aerated concrete is inferior to other materials. However, this is often compensated by the lower static load on the building due to the low weight of aerated concrete.

Tips & Tricks

Aerated concrete blocks are the easiest way to build a massive wall yourself.
