Why Choose Cellular Concrete For Construction

 

 Cellular concrete is an insulating building material used for structural construction, and it is a concrete block, just like a cinder block. It is more insulating than a cinder block, allowing bearing or non-bearing walls to be constructed.

 Cellular concrete: a natural composition

Cellular concrete is composed of a mixture of several natural elements:

 sand,

 cement,

 lime,

 aluminum powder,

 gypsum,

 water.

 Different types of cellular concrete: smooth, U-shaped, angles…

 Cellular concrete offers a wide range of blocks for every use in construction:

 smooth blocks,

 interlocking blocks for easy installation,

 blocks of angles,

 U-shaped blocks,

 lintel blocks, etc.

 All types of construction with cellular concrete

 The laying is done with thin joints with mortar glue and allows the construction of the following:

 load-bearing walls,

 partitions,

 dividing walls,

 floors,

and also roofing and cladding.

 Cellular concrete dimensions

 The standard dimensions of cellular concrete are 62.5 cm × 25 cm × 20 cm.

 In addition to the standard, you can find blocks of different thicknesses:

 25 cm,

 30 cm,

 6.5 cm,

 50 cm.

 The length is also adapted to the type of construction.

 Cellular concrete: robust and insulating

 Cellular concrete blocks are light, strong, and stable while providing good thermal insulation for buildings.

 Thermal insulation: no insulation from the inside

 Cellular concrete constructions can do without an internal insulation system. Thermal bridges are limited when the installation is carried out according to the rules of the art. This type of construction offers a significant gain in living space: between 4 and 6 % compared to traditional concrete construction with insulating interior lining (20 cm of wall + 6 cm of lining).

 Thermal inertia of cellular concrete: energy savings

 Cellular concrete balances the temperature inside the house.

 This one can store heat during the day and keep it to restore it when the temperature is lower, in the evening, in the house. This, therefore, allows energy savings.

 Hygro-regulation of cellular concrete

 When the construction is coated with a suitable product, the structure does not let water through, allowing water vapor to circulate from inside to outside. The habitat is, therefore, healthy, with no risk of mold growth.

 Cellular concrete: construction principle

 Cellular concrete requires a perfectly level surface to be laid and is not very complicated to install if you observe the manufacturer’s recommendations.

 Cellular concrete: using suitable material for the installation

 Cellular concrete requires specific tools and materials for its installation:

 electric saw with big teeth or selfish saw,

 glue comb,

 glue mortar,

 and, of course, the classic mason’s tools.

 Laying cellular concrete: the steps

 The first row is decisive for the rest of the work. It must be perfect, and we recommend you use a laser level:

Steps for Building a Cellular Concrete Wall

KEY STEPS	TO DO
Installation of the first row	It is done on a perfectly level and plumb surface: – either on a waterproof concrete base of 600 kg/m3, – or directly on a flat slab with adhesive mortar.
Laying the first corner blocks	The installation starts with the corners with, if necessary, special blocks to pass the chain link. The marking of the future construction is done on the ground and is facilitated by the installation of a marking cord: the use of a laser level is then very practical. The blocks are then placed at each end: pull a cord between the blocks to facilitate alignment. Check for level and plumb. Glue the vertical joint before installing the block and only on specific corner blocks since they are not profiled.
Installation of the second row	– The blocks of the first row are glued with the glue comb. – The cellular concrete block is presented on the block below, with staggered joints, and is made to rest lightly on the lower edge before being put in place in one go, without moving it to avoid removing the glue. – The handles present on certain types of blocks are very useful for this positioning. – Check the level, plumb, and tap with the mallet to adhere to the glue and adjust the level.
Checking the level	– Using an aluminum mason’s rule that you slide over the blocks, check that all the blocks are perfectly level. – If not, there is a gray mark on the cellular concrete. – It is then possible to grind the block with a rasp.
