The "Portafoam System"
Lightweight Foamed Concrete The Easy Way
---------
We have been supplying the technology for the production of lightweight foamed or cellular concrete locally & worldwide. We from small to large scale production of pre cast wall blocks and panels. In addition we also have experience in providing foaming technology for cast in-situ wall systems, decorative architectural components, floor screeds,roof insulation and also foundations / or bases for roads and building aprons.
Our technology is not just about equipment & materials but its also know how & method in producing quality foam concrete . Therefore we place great emphasis on equipment, training & consultancy. We have been providing training & tailoring our systems to small & medium builders for some time now and have exported our technology overseas.
We have made production of lightweight foam concrete simple with low capital investment and we have tailored our equipment & techniques towards this end. Our equipment is user friendly, easy to install
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.
-------------------
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.

We market 2 types of foaming agents;
a)Synthetic – suitable for densities of 1000 kg/m3 and above.
b)Protein - suitable for densities from 400 kg/m3 to 1600 kg/m3.
Foams from our protein foaming agents comes from natural sources and have a weight of around 80 g /liter and expansion of about 12.5 x using Portafoam foam generator. They generally are more stable than synthetic foams but have a shorter shelf life of about 12 months in open conditions. They also give a higher strength of concrete compared to synthetic foams.

Dilution of foam concentrate can vary from 1:33 to 1: 39
40 lit premix expands to about 500 lit stable foam @ about 80 g/lit foam weight
Synthetic foams have a density of about 40 g/liter with an expansion of about 25 x using Portafoam. They are very stable at concrete densities above 1000 kg/m3 and give good strength. Their shelf life is about 16 months under sealed conditions.
20 lit premix expands to 500 lit stable foam at about 40 g/lit foam weight
Our foaming agents are of top quality and have been proven by its usage in many countries around the world for various uses such as block production, in-situ concrete, decorative concrete and void filling. For further inquiries contact :
Technical Assistance
We have 3 types ;
1) Basic - Learn about the basic principles of making foam concrete.
2) Advanced - Save R&D time and use our special formulations & methods and start making your product using foam concrete.
3) Special Consultancy - Ask us to look at your production & quality and on a project to project basis.
Some may think that making foam concrete is simply mixing foam with some basic raw materials. Contrary to this, making good quality foam concrete is an art and has to be learnt. Just like making a cake , even if you have right equipment and materials you may not have the right recipe or technique in making it, so you end up with an inferior product.
Making foamed concrete requires more than just having the equipment
Foam concrete can be made in a range densities using various mix design ratios depending on the application. No single mix design or formulation can apply or is best for all types of jobs. Some projects can fail due to the lack of understanding of the properties and performance of foam concrete.
Being a University company, we have data from hundreds of castings and have been involved in training many private and public corporations. We have the equipment and experience to advise and train you so that you can produce foam concrete of the right quality. We understand foam concrete better and can help you to implement your projects.
Some of the areas covered in our technical assistance are;
1.Foam Properties & Adjustments to the foam generator
3.Flow Rates & Quality of foam ( e.g. foam stability ).
4.Overcoming mistakes in mixing and other malfunctions.
5.Raw materials, their properties and use in foam concrete
6.Mix design of foam concrete ( standard mix)
7.Basic mixing of foam concrete (e.g. mixing procedures, w/c ratio, flow test, density test)
8.Control of target densities ( eg. wet & dry density )
9. Factors controlling strength, shrinkage and absorption of product.
10. Mixing procedures, efficiency and timing of mixers
Training & technical assistance can be carried out at USM ( a local university on the beautiful island of Penang, Malaysia) or at your/the client premises if required. Hotel accommodation can be arranged.
Mixers for Foamed Concrete
Although mixing of foamed concrete can be done by using normal drum or pan mixers, it is always better to use mixers dedicated to mixing foamed concrete in order to get the foam into the mix quickly and obtain a uniform and smooth mix. This is especially important in the production of foamed concrete blocks and panels.
One such mixer system is the LN 300 E and LN 300 D . Letters at the end signify if its electrical or diesel operated. The capacity of each mixer is 1m3 and this size has been found to allow efficient mixing of foamed concrete.
LN 300 E is an electrical operated mixer with top loading principle. It has several features such as replaceable steel blades, rubber linings, pneumatic cleaning, special exit valve, chutes and can even be fitted with a PM2 or PM3 foam generator. The mixer allows about 1 to 2 m3 / hr depending on the batching system used.
The LN - 300 E mixer complete with control panel, exit valve, steel platform for top access. Its compatible for both labor and machine operated batching system
The mixers can be attached to a conveyor system with a hopper. With this configuration, the raw materials can be batched quickly without mistakes on site. A special hopper can also be attached to the exit point to allow storage of foam concrete and free the mixer for the next mix.
The mixers can also be attached to our special foam concrete pumps DN 100 . These pumps operate in accordance with the speed of the mixer and allow quick placement of foamed concrete especially for cast in-situ work.
