Frequent Questions

Explore all the applications of cellular concrete.

Cellular concrete is prepared by mixing water, concrete, foam and possibly inert substances in special mixers equipped with foam generators.

It is a lightweight concrete, made from a mixture of air and concrete.

Cellular concrete is used in the erection of buildings for civil use, making houses which respond better to requirements on soundproofing and thermal insulation. Furthermore, cellular concrete is indicated for restoration, in particular for energy adaptations; it is also possible to lighten wooden floors and roofs through its use. Not to be forgotten is its use in industrial building, where resistance and safety of the materials used in erecting industrial sheds and production establishments is required. Neither should the speed of laying the material and the use of pre-fabricated panels in cellular concrete be overlooked.
There is also a growth in geotechnical applications of filling cavities and for road cavities.

Cellular concrete does not catch fire even if subjected to direct flames. It is classified as Euroclass A1.
Resistance to fire: EI 180 of 10 cm thickness (as per the certificate in our possession).

Isoltech proposes a special acrylic additive for cellular concrete, to be mixed with local sand and concrete, to produce a thin filmed binding agent for perfectly binding cellular concrete.

Plaster for use on cellular concrete must be made of concrete and local sand, mixed with acrylic additive ACRI 105, according to Isoltech’s indications.

Isoltech supplies complete and exhaustive technical documentation on cellular concrete for various densities.

Isoltech supplies all certification in its possession to professionals, clients, appliers and building companies

The absorption of water is really very modest for average densities, on the higher specific weights it is nearly nothing, while on the lower densities, it may be considered as pervious.

No, Isoltech does not produce or sell cellular concrete blocks. Isoltech supplies its clients with the necessary technology for production of cellular concrete and the expertise to enable autonomous production. In addition to foaming agents, auxiliary additives and machinery, the company supplies training and support for initiating production on site.

Autoclaved cellular concrete is prepared in large energy-consuming industrial plant, while non-autoclaved cellular concrete is produced in small or medium sized plants with very low energy consumption, and is produced close to the user market (zero miles).

The main uses of cellular concrete are: Thermal insulation, roofing slopes and terrace suspended layers, flooring sub-layers, geo-technic filling, blocks for walling, on site vertical filling, pre-fabricated panels.

GLOSSARY OF SUSTAINABLE BUILDING


Cellular concrete, through its mass and porous surface, muffles the propagation of the sound wave and guarantees exceptional insulation, be that for the passing wave or for sound refraction.

Reduction in pressure of the sound wave obtained with cellular concrete.

Cellular concrete made up of very fine silica sand and of concrete, with other components, to be finished off maturing in an autoclave.

Application of the cellular concrete. Nonetheless, it is considered as a real building system which allows for the creation of vertical structures with high thermal insulation. For more information about Cast in Situ Application …

Artificial hydraulic binder which is transformed into a thermal insulator with its cellular structure.

“Dry density” is defined as the weight of a cellular concrete mix when the mixing water in excess of the hydration water has evaporated.

Product obtained from a foaming agent in a water solution with compressed air; indispensable for production of cellular concrete.

Agent which produces foam for obtaining cellular concrete. For more information refer to Foaming Agents web page.

“Humid density” is defined as the weight of a cellular concrete mix in its fresh state before placing into service. Its value is expressed in kg/m3, and is the sum of the concrete and the water necessary for working and placing into service; the weight of the foam inserted is possibly inert.

Light weight and economical foamed volume obtained with cellular concrete.

Reduction in sound wave pressure obtained with cellular concrete.

Together with layers between the flooring slabs and the paving, where according to the function of the thickness, it could be single or double layered.

This is the technology developed by Isoltech to produce cellular concrete with a density of between 100 and 200 kg/m3, guaranteeing an elevated potential for insulation.

A complete and ecological construction system which does not require furnaces and autoclaves. Uses very little energy to produce a cellular concrete, utilizing extremely limited amounts of natural resources. A building solution which significantly lowers production costs and, thanks to its simplicity, is very attractive for emerging economies.
