These make it possible to maintain a comfortable indoor temperature, without thermal energy loss, guaranteeing considerable cost savings in the use of environmental air conditioning systems.
These increase the breathability of the walls preventing the formation of mould and considerably lightening the structure of the building.

How to use CLC blocks.
Applications.

CLC blocks (or FOAM CONCRETE) are used as filling for outdoor walls and to build partition walls, as their breathability, lightweight and fire resistance make them ideal.  Also used for the construction of load-bearing walls in non-earthquake areas, with a thickness of no less than 25 cm and a minimum density of 800 – 1,000 Kg/m³ with smooth blocks or with holes for the installation of steel bars and concrete casting.
Lastly cellular concrete blocks are very commonly used for the fencing of containment walls or the perimeter of dwellings.

How to make CLC blocks.
Material and machinery for the production of CLC blocks.

In the production of CLC blocks, the raw materials (water, cement and sand) are mixed in a mixer, the foam produced by the TECHCELL HT foaming agent and by a foam generator is then added.
For a maximum daily production of 15 m³, the material is pumped into moulds in series and after at least 8 hours the produced panels can be cut into blocks of the required sizes.

For larger production, the material is poured into 1 m³ moulds and cut into blocks after at least 8 hours.
The drying stage is carried out without the addition of specific machinery such as furnaces or autoclaves.
The FOAM CONCRETE (CLC) is left in the moulds until the cutting phase.

Thanks to the type of blade of our Block cutter, the material can be cut wet or dry therefore it is not necessary to cut within a certain amount of time.

To increase the technical characteristics of CLC blocks, the auxiliary additives for CLC, DSP XL, FBR, HDR can be added to the mixture.

Advantages to the use and the production of CLC blocks.

Thermal insulation, lightweight, reduced cost of production, easy workability and versatility (ideal of construction and restructuring). With Coisoimper machines, the independent production of cellular concrete blocks required for the construction of civil and industrial buildings is even more advantageous.

Is suggested to use also the auxiliary additives for CLC to increase the technical characteristics.

The material is poured into specific forms that determine the panel size.
Based on the forms, the panels can have smooth sides, male/female coupling or holes to pass cables through or to lighten the weight.
The dry density of the prefabricated panels depends on the end use, it can vary from 600 Kg/m3 to 1,000 Kg/m3.
Based on size and weight, the panels can be moved manually or with due systems. 

Advantages to the use and the production of CLC panels.

There are multiple advantages to using CLC panels, the most important being insulation and lightweight.
They are also rigid and stable and are ideal for construction and restructuring, in addition to having a reduced production cost.

A quick, low cost, single-storey home construction system (Social House) without the need for a factory with production line as the walls are cast directly on site, with FOAM CONCRETE.
Casting is carried out directly on site in formwork where steel reinforcement is already installed, if necessary, and the electrical and hydraulic systems.

Where to use the technique CLC walls cast on site?

The on-site casting technique for walls and partitions can be used for the complete construction of low cost, single-storey homes (Social House) or for filling non load bearing walls where the load bearing structure (pillars and beams) are made with concrete or steel. In this application the thickness of the outer walls must not be less than 20 cm with minimum density of 1.000-1.200 kg/m³. While the partition walls can have a minimum thickness of 10 cm.
The on-site wall casting system is also suited for building fences and containment walls.
Walls made with FOAM CONCRETE maintain a comfortable indoor climate, without thermal energy loss, also allowing considerable savings on the costs of use in environmental conditioning systems.
It also increases the transpirability of the walls preventing the formation of mould and considerably lightening the structure of the building.

How to cast CLC walls on site?

It is particularly easy to cast walls on site using the COISOIMPER system.
After installing the formwork, the FOAM CONCRETE is mixed and pumped by a complete machine, KOMPATTO R16, directly into the formwork.
From the next day the formwork can be removed, and it can be of any type as long as it is resistant to hydrostatic pressure and watertight.
To make CLC walls all you need are water, cement, sand and foaming agent TECHCELL HT.

To increase the technical characteristics of CLC walls, the auxiliary additives for CLC, DSP XL, FBR, HDR can be added to the mixture.

Filling and stabilization of the subsoil with FOAM CONCRETE.

Filling and stabilization of the subsoil with FOAM CONCRETE.

Geotechnical filling with FOAM CONCRETE (CLC) is an alternative to digging and therefore to replacing unsuitable and unstable land (clay or marshy) with compacting land or other traditional materials suited to modifying the subsoil.

FOAM CONCRETE on top of unstable soil reduces the vertical dead load and increases the amortization capacity and stability with the addition of minimum weight.

Applications of FOAM CONCRETE in the geotechnical filling system.

FOAM CONCRETE is ideal in situations where it is necessary to make areas of clay soil or with stagnant water, stable.
Its fluid characteristic means it can fill any cavity that is irregular or hard to reach with heavy-duty machinery (such as lorries, wheel tractor-scrapers…).
It can also be used to fill derelict cavities (tunnels, cisterns, mines), to fill road ramps, to fill arches in historical centres and to insulate gas lines.

Advantages of FOAM CONCRETE in geotechnical filling.

The Geotech filling system has many advantages, the first being that of facilitating changes to the subsoil, making the land stable using less resources and energy than with traditional methods, without having negative effects on the environment and maintaining a high level of soil permeability.

FOAM CONCRETE also has a high logistic advantage as great amounts of material are not transported, nor is compacting roller machinery, used, rather it is self-produced directly on site with small machines.

Plus, the raw materials are simply water, concrete and TECHCELL foaming additive. Its fluidity allows fast application and is self-compacting and therefore does not need any special processing for levelling.

Slabs in FOAM CONCRETE, used for cladding Steel Frame structure.

The SLABS HP are lightweight and easy to handle, produced with a medium FOAM CONCRETE mixture.
They can be self-manufactured using COISOIMPER systems and local raw materials combined with specific COISOIMPER additives.

The main characteristics of CLC SLABS HP are flexural strength and therefore strong resistance to hydrostatic pressure and with a 2 cm thickness. The standard dimensions are 75 x 60 cm and the weight is 9 kg.

Technical characteristics of CLC SLABS HP:
– High compressive strength
– Resistance to impact
– Flexural strength (during the filling of FOAM CONCRETE)
– Tear resistance (for fixing wall units)
– Fire resistance and protection to the Steel Frame
– Lightness (so good thermal insulation).

Using CLC SLABS HP.

The CLC SLABS HP are mainly used to replace fiber cement panels or similar and as cladding on exterior and partition walls on steel structures.
Plus, the slabs are used as “disposable formwork” thanks to the flexural strength during pumping, and therefore the use of formwork is not required.
