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. |

(New Store of a World Renowned Industrial/Commercial Conglomerate) | ||||||||||||||||||||||
Great Adhesion, High Resiliency, Low Load per Unit Area | ||||||||||||||||||||||
SHOPPING MALLS, MULTI-FLOOR OFFICES, SCHOOLS, HOSPITALS, INDUSTRIAL FACILITIES AND MANY MORE | ||||||||||||||||||||||
|
||||||||||||||||||||||
Per square foot load increase can be less than 3 lbs. at 1 inch thickness | Great adhesion to clean concrete base even without priming | |||||||||||||||||||||
Unlike the conventional gypsum based underlayment, Allied foam cement grout is exterior durable with low water absorption and excellent water resistance. | Controllable slump that allows ease of slope build-up or screed to level | |||||||||||||||||||||
High tensile strength, good vibration/crack resistance and great adhesion to various load-bearing topping materials | Typical dry densities from 30 - 40 pcf (480 - 650 kg/m3), ideal lightweight grout for fixing uneven floors. | |||||||||||||||||||||
Allied foam grout can be pumped over several hundred feet while still maintains desired performances | Much more cost effective and with significantly better sound and thermal insulations versus conventional tile grout |

The World's 1st Low Slump Cement Geotechnical Roof Fill used Allied's Cement Composite Design, Foam Products & Machinery. | ||||||||
The award winning facility places more than half the total square footage of the facility below grade, and incorporates three functioning green roofs. The south façade of the Northwest Science Building defines a new South Yard, equipped with low landscape furniture. The yard is a green roof over extensive basement levels, with skylights bringing daylight into the underground areas. |
