Lightweight foam 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 500kg/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, floor & roof screeds, trench reinstatement, road foundations and void filling.
The Portafoam foam generator is a machine that produces stable foam from a mixture of chemical foaming agent, water, and air.
| The Portafoam PM2 system is most versatile since it can mix from 0.1 m3 up to 3 cubic meters of foamed concrete at one time |
This foam generator, which runs from an air compressor, consists of components such as the MSD unit, foaming unit, and a lance unit. Unlike pressure tank systems, Portafoam runs on a principle of providing continuous and constant foam with minimum refill. They are also more accurate and easier to run compared to fully air operated systems. 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, 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. synthetic or protein). The Portafoam foaming generator can be attached to several other devices such as an auto-timer control, pressurized holding tanks and other proportioning systems which makes foam concrete production more efficient or gives greater flexibility to foam generation.
| The Portafoam PM-3 system has a large flow rate and is fitted with digital timer for accurate dosage of foam |
Portafoam comes in 3 different models, which is the TM-1, PM-2 and PM-3 which yields about 100 lit/min, 200 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.
