Foam Concrete provides us with tomorrow´s knowledge today and helps us, using the most innovative technology, to optimize our building processes, whilst at the same time improving product quality and ecological sustainability.
Foam concrete is a type of porous concrete. According to its features and uses it is similar to aerated concrete.
Foam concrete is created by uniform distribution of air bubbles throughout the mass of concrete.
Foam concrete is produced by mechanical mixing of foam prepared in advance with concrete mixture, and not with the help of chemical reactions.
Foam is prepared in special device – foam generator and after that mixing in special mixer.
Construction companies can increase profits and save valuable time using Lightweight cellular concrete (LCC) technologies.
By working together and integrating the technologies used in buildings, we can optimize them to reduce energy consumption and improve safety.
LCC use can be a partial solution for several environmental problems, deforestation could be substantially reduced by relinquishing the demand for timber used in residential construction.
LCC is an environmental friendly technology, that can be executed at the project site, consist to mix a base mortar and preformed foam, the foam is produced with a foam generator unit, adding foam in the 20% to 50% range produces concrete with densities ranging from 1900 Kg/m3 down to 1200 Kg/m3, the result is a lightweight cellular concrete that can be used in non-structural and structural precast and cast-in-place applications, with a significant reduction in transportation, labour and equipment costs.
Additional benefits in lower densities include greater thermal insulation, improved sound absorption and decreased permeability to water, lower thermal conductivity improves fire resistance, the LCC can be cut, nailed and screw without pre-drilling.
It is important to have a mix design, this will depend on the strength requirements needed for the particular application, desired densities and compressive strengths are controlled by altering the amount of foam, sand, and cement in the mix, substantial increases in strength will result by reduction of water/cement ratio, such as is possible with a efficient mixing equipment.
Other admixtures such as water reducing agents may contribute to strength increases.
As with ordinary concrete, the compressive strength at any given density and mix proportion will also vary with the type of cement, quality and fineness of the sand and final water content of the mix.
Foam Concrete is normal concrete with bubbles of air inside. Therefore it has the same characteristics with many additional advantages.
CLC (foam concrete) blocks are used for building cottages, wall insulation in multi-storey buildings and internal partitions.
CLC also can be produced and poured for floors and roofs on-site. In roofs it can be used because of very good insulating and lightweight.
For floors CLC offers faster installation and a less expensive option because of the flowing and self-levelling properties.
CLC is easy to produce. The ingredients are cement, sand, water and foaming agent.
The components are mixed in Foam-Prof machine and in this mix added the foam that produced in special foam generator that attached to Foam-Prof machine.
The produced foam concrete pour into the special moulds for blocks or on the floor (roof) on the construction site.
