Foam concrete – definition and physical characteristics

Foam concrete is a type of porous concrete. According to its features and uses it is similar to aerated concrete. The synonyms are:

aerated concrete

lightweight concrete

porous concrete

  • The foam concrete (a non-stem-cured one) – is a new building
  • material that is used within the needs of house-building and industrial construction.
  • A non-steam cured foam-concrete exceeds a steam cured kind in many ways. It does not need frying ovens to be produced.
  •   The factory can be situated even on a construction site.
  • However it does not yield to a steam-cured one in characteristics.
foam concrete
Foam concrete
  • Foam concreteis 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. (For example machine Foam-Prof consist from special mixer and foam generator mounting together).
here we will look at the main feature of foam concrete and will compare it with other materials
Here we will look at the main feature of foam concrete and will compare it with other materials.
  • Foam-Prof machines could produce foam concrete with different densities from 200kg/cub.m. to 1600kg/cub.m.
density 300 500 kg m3 19 38 lbs ft3
Density 300-500 kg/m3 (19-38 lbs/ft3)
  • Density 300-500 kg/m3 (19-38 lbs/ft3) Made with Cement & Foam Only
  • Foam concrete with this densities is used in roof and floor as insulation against heat and sound and is applied on rigid floors (i.e. in itself it is not a structural material). It is used interspace filling between brickwork leaves in underground walls, insulation in hollow blocks and any other filling situation where high insulating properties are required.
density 600 900 kg m3 38 56 lbs ft3
Density 600-900 kg/m3 (38-56 lbs/ft3)
  • Density 600-900 kg/m3 (38-56 lbs/ft3) Made with Sand, Cement & Foam
  • Used for the manufacture of precast blocks and panels for curtain and partition walls, slabs for false ceilings, thermal insulation and soundproofing screeds in multi-level residential and commercial buildings. Foam concrete of this density range is also ideal for bulk fill application.
density 1000 1200 kg m3 56 75 lbs ft3
Density 1000-1200 kg/m3 (56-75 lbs/ft3)
  • Density 1000-1200 kg/m3 (56-75 lbs/ft3) Made with Sand, Cement & Foam
  • This material is used in concrete blocks and panels for outer leaves of buildings, architectural ornamentation as well as partition walls, concrete slabs for roofing and floor screeds.
density 1200 1600 kg m3 75 100 lbs ft3
Density 1200-1600 kg/m3 (75-100 lbs/ft3)
  • This material is used in precast panels of any dimensio for commercial and industrial use, garden ornaments and other uses where structural concrete of light weight is an advantage.

water absorption
Water Absorption
  • Trials undertaken have shown that the closed cell bubble structure produced GreenFroth protein foaming agent create a foamed concrete with very low water absorption.
  • The higher the air content the higher the water absorption figure with a fully submerged sample of a mid density (770kg/m3) foamed concrete absorbing just 13% of water by weight over a 10 day period. A dense concrete block submerged for the same time absorbed over 50% of water by weight.
fire resistance
Fire Resistance
  • Foam concrete is extremely fire resistant and well suited to applications where fire is a risk. Test have shown that in addition to prolonged fire protection, the application of intense heat, such as a high energy flame held close to the surface, does not cause the concrete to spall or explode as is the case with normal dense weight concrete.
foam concrete advantages
Foam concrete - advantages.
  • Foam concreteis an almost ageless and everlasting material not subject to the impact of time. It does not decompose and is as durable as rock. High compression resistance allows to use produce with lower volumetric weight while construction, which increases the temperature lag of a wall.
  • Foam concrete prevents loss of heat in winter, is humidity proof, allows to avoid very high temperatures in summer and control air humidity in a room by absorbing and output of moisture, thus helping create a favourable microclimate (Microclimate in a wooden house).
quickness of mounting
  • Small density, and, therefore, lightness of foam concrete, large sizes of blocks compared with bricks, allow to increase the speed of laying by several times. Foam concrete is easy to process and trim – to cut channels and holes for electrical wiring, sockets, and pipes. The simplicity of laying is reached through high exactness of linear dimensions, the tolerance is +/- 1 mm.
acousting insulation
  • Foam concrete has a relatively high property of acoustical absorption. In buildings constructed of porous concrete the acting requirements for acoustic insulation are met.
ecological compatibility
  • During maintenance, foam concrete does not produce toxic substances and in its ecological compatibility is second only to wood. Compare: the coefficient of ecological compatibility of porous concrete is 2; of wood – 1; of brick – 10; of keramzite blocks – 20.
  • Due to high workability, it is possible to produce various shapes of corners, arches, pyramids, which will attach beauty and architectural expressiveness to your house.
  • High geometrical exactness of dimensions of concrete produce allows to lay blocks on glue, to avoid “frost bridges” in a wall and to make inner and outer plaster thinner. Foam concrete weighs from 10% to 87% less than standard heavy concrete. Sufficient reduction of weight leads to sufficient economy on basements.
fire safety
  • Foam concrete produce protect from fire spread and correspond to the first degree of refractoriness, which is proved by tests.
  • Thus, it is can be used in fire-proof constructions. Under the impact of intensive heat, like blow lamp, on the surface of foam concrete, it does not split or blow, as it happens with heavy concrete. AS a result, armature is longer protected from heating. Tests show that foam concrete 150 mm wide can protect from fire for 4 hours. During tests carried out in Australia, an outer side of a foam concrete panel 150 mm wide was exposed to temperatures up to 12000C.
  • Favourable combination of weight, volume and packaging makes all building constructions convenient for transportation and allow to use motor or railway transport
range of uses
  • Thermal and acoustic insulation of roofs, floors, warming of pipes, production of collapsible blocks and panels of partitions in buildings, as well as floors and basements foam concrete of higher density.

  • When comparing foam concrete with other materials, one must keep in mind that:
  • it is ecologically clean, “breathes”, uninflammable.
  • easy to produce in steady-state conditions as well as on a construction site
  • is produced from components available in any region
  • its prime cost is low
