WHY FOAM STABILITY MATTERS TO THE CEMENT, CONCRETE & BUILDING INDUSTRIES

Problems associated with most of the conventional surfactant and protein based foam agents.

  Low early & 28 days strength

It is well-documented that protein based foam cement has serious foam collapse and compatibility problems when it is formulated into high strength cement and concrete with low water/cement ratios and superplasticizers. Such drawbacks significantly limited such foam agents for use in the high performance cement and concrete industries.

  Foam collapse and loss of air entrainment in high fly ash containing cement & concrete

It is known that the carbon content in fly ash will adsorb most of the surfactant foam agents and causes foam collapse and reduces the air entrainment efficiency of such air entraining additives. Various equipment and deivice have to be used to monitor the increase of foam agent dosage when such problems take place in the cement and concrete slurries.

  coarse texture, appearance and poor handlability as density decreases

As shown in the pictures above, most of the surfactant and protein based foam cement have coarser textures and poor handling features caused by the limited foam stability in the composites. Such shortcomings become more serious at low densities where increased foam content is needed. Such weaknesses will prevent their usage in high end building materials such as decorative stones and roof/wall panels.

 

What a stable foam can do for the cement, concrete & BUILDING industries

 

  High stability of the Allied foam systems and the product’s excellent compatibility with various charge-containing additives such as plasticizers and superplasticers allow foamed cement slurries be used at very low water/cement ratios (as low as 0.26) and formulated into various high early and 28 days strength cement and concrete composites for the building industry.

  The inertness and the full compatibility of the Allied foam systems toward the various hydrophilic and hydrophobic additives/particles of different nature allow them to be used with all kinds of fly ash formulated cement and concrete for a diversity of applications.

  Fine Texture and Good Strength/Handling Features derived from Allied stable foams make cured building members extremely appealing and durable.

TECH LICENSE OPPORTUNITIES (January, 2014)

Allied Foam Tech, through its ~ 20 years of internal R & D effort and global industrial experience in building trade, has developed a wide range of proprietary lightweight building composites, process and performance properties based on its patent pending lightweight fiber cement technologies and composites.  Major building product manufacturers interested in licensing rights please click here.

A few highlights are given below:

·         1. Superlight and flexible cement sheets with great adhesion characteristics, high water resistance, and high impact and compressive strengths (MOR > 750 psi,  indented compressive strength > 1,000 psi and 24 inches static water column test > 48 hours).

·         2. Lightweight and flexible (roll forming) decorative sheetings for various exterior or interior wall wrap or wall covering applications.

·          3. Asphalt-free flexible shingle (110-130 mils) and underlayment materials (50 to 70 mils) with UV resistance, freeze-thaw stablility, great coating and granule adhesion, tear strength and lightweight that is not available in the current roofing industry.

·          4. Foamed curable thin sheets, with their uv stability, flexibility, high tensile strength, great adhesion to metal and water resistance, are very adaptable for the manufacture of roofing shakes and metal roof tile composites.

·          5. Lightweight flexible cementitious coatings for the various commercial foam boards such as polystyrene and polyurethane foam boards.

·          6. Lightweight cast stones with high mouldability (low slump), good fire resistance and quick demolding behavior, high tensile strength and adhesion for pigment and coloring should be very suitable for direct replacement of the various heavy stone or other concrete cast stone products.

·          7. The flexible cementitious composites allows prefabricated or cast in place sandwich panels of various kinds to be made. Extrudable cementitous composites can also be engineered allowing for friendly adaptation of the various manufacturing process, curing and storage capabilities.

Such foam cement can easily reach a compressive strength of > 270 psi at an air dried density of 29 pcf.

*All the commercial pervious lightweight cement systems rely their permeability on either the very coarse open pores or the interconnected capillaries derived from severe foam collapse. Such cellular cement composites are typically very low in compressive strength, e.g. 80 - 150 psi at densities ~ 30 pcf.

Foam concrete or lightweight concrete derived from Allied's aqueous foams are suitable for both precast and cast-in-place applications. Some of the highly insulative cementitious foams at densities 48 kg/m3(3 pcf) to 645 kg/m3(40 pcf) or higher can be used as block fills, lightweight roof deck and void-fill materials. Good strength characteristics with reduced weight make lightweight concrete based on Allied's aqueous foams  suitable for structural and semi-structural applications such as lightweight partitions, wall and floor panels, and lightweight blocks. Cementitious foams derived from Allied's premium systems are suitable for thin layer coating applications where specific performance criteria are required.

Foamed concrete and foamed cement made with Allied's foam have very fine pore structure, unlike that made with conventional proteinaceous and surfactant foams. The pore structure of Allied's foams hardly show any sign of deterioration as the density of the foamed cement decreases to below 160 kg/m3 (10 pcf). At densities below 160 kg/m3, the pore texture of foamed cement derived from conventional foam agents becomes so coarse that most of them show severe structural collapse.

The dynamic nature of Allied foam systems allows different foam rheology to be incorporated into the host cement/concrete matrix to satisfy a wide range of slump loss requirements.

The inert nature of Allied foam systems makes them  compatible with different kinds of aggregates,  fillers, extenders,  retarders, accelerators, colorants, hydraulic inorganics and many other additives.

Highlights on Allied’s WORK with Foamed DECORATIVE STONES, Blocks and Foamed Panels
(WE PROVIDE FOAM PRODUCTS, FOAM MACHINERY AND TECH SERVICE IN PROCESS & MIX DESIGNS)
Autoclaved aerated concrete (AAC) was introduced  in Europe over half a century ago as a lightweight construction material. The key features AAC has over conventional foamed concrete are significantly better strength and lower shrinkage/cracking. However, most of the attempts over the last few decades to introduce AAC to the US either failed or hardly made any signifcant impact to the construction industry. The million of dollars of capital investment needed for the manufacture of AAC over the conventional precast plant is just one of the many reasons reported in the literature.
Freshly prepared decorative stone panels with low shrinkage and non-cracking features are shown below:
 
3.6 feet x 2.6 feet (1.1 meters x 0.8 meters)
Total weight = 28 pounds or 12.7 kg.

Extrudable Foam Cement Blocks

2. Improved Foamed Cement Roof Deck Designs 

Highly sloped industrial and residential roofdecks or roofings become possible with Allied's high slump-loss foamed cement product and mix design.

lightweight roof deck,foamed concrete Allied's stable foam with high slump loss can be applied directly on corrugated metal sheets of new or repaired roofs without foam dewatering and possible water leakage to the interior structure of the floors underneath while such problems have always been associated with conventional cellular concrete roof decks.

lightweight roof deck,foamed concrete Using Allied’s 35pcf/10 pcf foamed cement composite as roof deck structure will achieve the right combination of thermal insulation and light weight like conventional cellular concrete/styrofoam blocks but with appreciable labor and time savings and the flexibility in roof deck designs with varied shapes and contours not achievable before.

Strength Development and Water Uptake of Foamed Cement 
Allied foams are compatible with different kinds of cement, fly ash, sand/aggregate fillers, retarders, accelerators and water reducers. The AFT-400 series of foam reagents provide cement and concrete with very low water uptake. Cementitious foams at densities as low as one tenth (1/10) that of dense concrete will still maintain lower than 15% (by volume) water uptake in a 24 hour water immersion test.
The following table shows some typical strength and water uptake characteristics of a lightweight cement formulation using Allied AFT-400:
