LITEBUILT® AERATED LIGHTWEIGHT CONCRETE
Goldbar
Aerated Lightweight Concrete has been on the market since the early 70's and there is a host of chemical manufacturers who claim to have the right formulation to produce aerated concrete.
However, there are few companies who can come up with genuine reference projects where their product has been used successfully (this excludes geotechnical applications where virtually any foaming product can be used).
The fact of the matter is that most foaming chemicals have a high content of organic protein and the source of supply can be from a number of sources, which inevitably leads to wide variations in strength and consistency in the final product – aerated concrete. Moreover, other raw materials used in the process like cement and sand also differ between the various suppliers.
When PAN PACIFIC ENGINEERING PTY LTD got involved in the late 80ís in aerated concrete applications, we started to realize that there was a total lack of serious technical support, realizing however that this material is a product of the future.
Our approach was different. We were focused on the application aspect of the product and – with lots of hard work, sweat and tears – made sure the final product was acceptable to Builders, Architects, consulting Engineers and Authorities.
After testing and using many of the chemical formulations available on the market, we came to the conclusion that – in order to control the quality of the final product – we had to produce our own, superior formulations which we market under our own trademark, namely LITEBUILT®.
This solves however only half of the problem. The more important aspect has been the continuous development of the manufacturing techniques for wallpanels, in situ casting and masonry blocks. Today we are able to claim that – to our knowledge – we have the only foamed concrete masonry block plant in operation in the world and there are numerous refer-ence sites in various countries where LITEBUILT® has been used, including major projects in Indonesia, Malaysia, Thailand.

LITEBUILT® PROCESS
Goldbar
The LITEBUILT® Aerated Lightweight Concrete process is based on the principle of entrapping a multitude of air bubbles in the concrete mix, who retain their structure during the curing period.
Firstly, the mix composition of cement / sand / water / foam according to specification has to be chosen. After batching the basic ingredients, LITEBUILT® Foaming Agent is introduced to the mix which then can be poured into panel molds of virtually any shape or size.
The LITEBUILT® Aerated Lightweight Concrete Mix normally cures in open air within about 24 hours (unless it is used in cold weather conditions) before handling is recommended.
It is possible to add other products to the LITEBUILT® Foam Mix to obtain lightweight composite concrete. Notably the use of various fibers increases the strength of the product and prevents cracking in adverse conditions.

ADVANTAGES OF LITEBUILT® AERATED LIGHTWEIGHT CONCRETE
Goldbar
Dot
Reduced weight, with a wide range of possible densities and strength. Compared with dense weight concrete, reduction in weight from 10% to 87% can be achieved.
Dot
The cost advantage would be typically around 15 to 20% (in Australia) compared with dense weight concrete.
Dot
Additional, substantial savings are achieved due to a lower deadweight of the building. Structural components and foundation cost are greatly reduced, in particular on high-rise projects.
Dot
Quick turn-around in the manufacturing process (24 hours – or less, if accelerators or steam curing methods are employed).
Dot
Fast construction speed because of precast panel technology – typically half, when compared with conventional construction methods.
Dot
Fire rated to a minimum of 2 hours for a 75 mm (3") thick panel (Test reports are available).
Dot
No obnoxious or toxic fume emission – no health hazards both in the manufactur-ing process and if product is subjected to heat (such as in case of fire).
Dot
Ongoing savings on power / energy costs (for air-conditioning and heating) are very substantial because of its thermal insulation qualities.
Dot
LITEBUILT® Aerated Lightweight Concrete can be sawn, sculptured with hand or common power tools and be penetrated by normal building nails and screws.
Dot
Compressive strength can be varied according to requirements. This is a function of density, moisture, mix proportion, chemical and physical characteristics of components materials and curing method. A 10% LITEBUILT® Foam content in the concrete mix renders it stronger than dense weight concrete. Higher percentage of foam in the mix reduces the strength in favor of lighter weight and better insulation characteristics.
Dot
Low water absorption because of its closed cellular structure.
Dot
Acoustic properties are such that sound is being absorbed, not reflected as is the case with dense weight concrete or brick walls.
Dot
The reduced weight facilitates cartage and handling and reduces transport cost.

HIGH RISE BUILDING DEVELOPMENT

LITEBUILT® Aerated Lightweight Concrete's major application is in the manufacture of lightweight panels and blocks.
LITEBUILT® Aerated Lightweight Concrete lends itself to tilt-up construction methods, and panels can be poured on site, saving transportation and handling costs.
If panels are precast in a plant situation, the reduced density also amounts to large savings in transportation and cranage.

STRUCTURAL APPLICATIONS

LITEBUILT® Aerated Lightweight Concrete is widely used in the manufacture of single skin lightweight concrete wall panels, employing tilt-up construction. This is an ideal situation for the manufacture of light commercial structures and factories as well as residential housing.
Alternatively, LITEBUILT® Aerated Lightweight Concrete can be used as a filling material between dense weight con-crete or other material to provide insulation. This is ideal for use in fire rated structures, such as solvent store, munitions storage facilities etc.
Sandwich panels with various surface materials, using LITEBUILT® Aerated Lightweight Concreteas a filler, are gaining increased acceptance for partition walls in office complexes, commercial walling, shopping centers and internal walls of residential houses and flats.

NON-STRUCTURAL APPLICATIONS
Roof / Floor Grading

LITEBUILT® Aerated Lightweight Concrete is often specified for use as a lightweight filling material, or used to provide graded insulation on roof projects beneath waterproofing membranes.
LITEBUILT® Aerated Lightweight Concrete is also recognized as a cost effective way to rehabilitate old floors (i.e. multi- storey buildings that have wooden floors) which require a lightweight self leveling compound.

VOID FILLING

The market for void filling is diverse. Currently used in the mining industry and applications in sewage lining grouting, this market has enormous potential.
Typical applications are void filling in mines, after excavation work or disused trenches and shafts. This is just one example of how this market can be developed.
Any industry that requires grouts for void filling can benefit from the utilization of LITEBUILT® Aerated Lightweight Concrete. For instance, in Oil Drilling, they pump massive quantities of grout around the shaft they place in the newly drilled hole. This market is currently untapped.
A number of companies are using LITEBUILT® Aerated Lightweight Concrete for use in the manufacture of such components, also encompassing such applications as decorative facades, lightweight garden ornaments, lightweight brick and reconstituted stone tiles etc.

COMPETITIVE ANALYSIS
Goldbar
There are several manufacturers producing lightweight concrete products, using a different process, which requires autoclave curing. Their process necessitates curing under high pressure and high temperatures, where the product rises similar to baking. Then the final product has to be cut into shape. Although the product is generally acceptable, the investment level for plant and equipment is considerable. A LITEBUILT® Aerated Lightweight Concrete Plant with similar output would generally require an investment of less than 20% compared to the cost of the autoclave process.
Another competitive product is the use of expanded Polystyrene beads in the concrete mix. This process has several drawbacks when compared with LITEBUILT® Aerated Lightweight Concrete. Firstly, the Polystyrene beads have to be chemically treated to loose their volatile electrostatic properties. This makes the process expensive. Secondly, Polystyrene tends to gasify in high heat, releasing toxic fumes. A number of Fire Authorities around the world have already expressed concern about the product and some countries have banned the product outright for construction use.
Other processes are using lightweight aggregates in their mix, however there are severe restrictions as to the minimum density (typically 1500 kg/m³ (94 lbs/ft³)) and raw materials are often expensive and need to be imported.
The LITEBUILT® process is markedly different from the competitors. It is very simple in its application, is chemically neutral and can be poured and cured in situ. Capital investment is minimal.
LITEBUILT® Masonry Blocks can be cut with a wire saw prior to full curing and they can be joined with ordinary mortar, unlike their competitors, who use a special compound.
