Aerated concrete is a mixture comprised of various natural components: sand , cement , lime , aluminum powder , gypsum , water.
The laying must be made with thin mortar joints and glue allows. It's for : bearing walls , partitions, partition walls , floors, but also roofs and siding .
The standard dimensions of the cellular concrete are as follows :62.5 cm ×25 cm ×20 cm .
In addition to the standard , you will find blocks of different thicknesses :25 cm ,30 cm,
6.5 cm,50 cm.
The length also adapts to the type of construction.
In France or Europe, the products must be CE marked to be put into circulation on the European market : CE marking is declarative .
In addition, require the NF which involves voluntary manufacturer to meet a series of requirements.
Aerated concrete : robust and insulating
The aerated concrete blocks are lightweight, robust and stable , while providing good thermal insulation of buildings .
Thermal insulation: no interior insulation
Cellular concrete constructions can spend an interior insulation system.
Thermal bridges are limited when laying is carried out in the rules of art .
This type of construction offers significant space saving surface space: between4 and6 % compared to traditional concrete construction with insulating inner liner (20 cm +6 cm wall lining ) .
Thermal inertia of cellular concrete : energy savings
Aerated concrete balance the temperature inside the housing .
It has the ability to store heat during the day and keep it for the return when the temperature is lower in the evening in the housing.
This allows for energy savings .
Hygro -regulation of cellular concrete
When construction is coated with a suitable product , the structure does not leave the water to pass and also to let the water vapor from the inside outwards .
The habitat is healthy, without the risk of mildew .
