Lightweight foamed concrete is normally made from mixing a stable foam to slurry of cement, sand & water.
This action incorporates small-enclosed air bubbles within the mortar thereby making it lighter and possessing special
properties such as low thermal conductivity and high fire resistance. Its density ranges from as low as 400kg/m3 to as high as 1600kg/m3
therefore allowing it to be used in a variety of applications such as pre - cast wall blocks and panels, cast in-situ lightweight walls, floor
& roof screeds, trench reinstatement, road foundations and void filling.
Fresh Foamed Concrete
The Portafoam foam generator is a machine that produces stable foam
from a mixture of chemical foaming agent, water, and air.
This foam generator, which runs from an air compressor, consists of components such as the mechanical delivery unit, foaming unit,
and a lance unit. These components allow great flexibility to the user in terms of the scale of production of foam concrete since it
can accommodate to future production requirements.
Portafoam is lightweight, modular , transportable and may be used on-site or adapted to existing concrete production plants. Its size, output, and mobility are also well suited for small to medium scale production and laboratory work on foam concrete.
Several control devices on Portafoam enable the adjustment of foam properties and allow it to work with different foaming agents (e.g. protein or synthetic) such as Noraite PA-1 and Noraite SA-1 which have been tested and are compatible with Portafoam. The Portafoam foaming generator can be attached to several other devices such as an auto-timer control, pressure tank delivery unit and valve junction box
which makes foam concrete production much more efficient.
Portafoam comes in 3 different models, which is the TM-2, PM-2 and PM-3 which yields about 150 lit/min, 250 lit/min and 500 lit/min
foam respectively. Portafoam is expandable, adjustable, easy to use and maintain and is one of the most competitively priced foam
generators in the building industry today.
