Cement Geofoam, Geotechnical Fill, Lightweight Fill

	Cement Geofoam Fill
FOR OVER 20 YEARS ALLIED HAS BEEN PROVIDING TO CLIENTS WITH THE HIGHEST PERFORMING AQUEOUS FOAM SOLUTIONS & TECHNOLOGIES IN THE INDUSTRY


CEMENT GEOFOAM, CEMENT GEOTECHNICAL FILL OR LIGHTWEIGHT CEMENT FILL
Allied Low Slump CEMENT Geofoam - A GAME CHANGER in the Geofoam MarkET
Allied "Cement Geofoam" will greatly simplify the application and cost relative to the "Expanded Polystyrene (eps) Geofoam"
Highway/Rail Embankment, Bridge Underfill, Landscape Architecture, Slope Stabilization, Levees, Airport Runway, Road Construction
Allied 5-50 pcf Low Slump Cement Geofoam	Conventional 07-2.0 PCF Low Density EPS Geofoam
Low load on the surrounding soil	Low load on the surrounding soil
Casting with a continuous low slump pour	stacking of individual blocks delivered on site
Shape & conform to the landscape easily with the low slump cast	Shape & conform to the landscape easily with the precast blocks
Foam formation on site through compressed air and foam agent	Huge number of eps blocks have to be delivered on site
No fire hazard, good solvent resistance	Fire hazard, lack of solvent resistance (geomembrane needed)
Intimate soil contact with easy surface leveling and slope build-up	Sand leveling or other means needed for block alignment
Uniform and bulk cast without gap, no concerns for buoyancy or individual piece heaving/floatation due to ground water	Inter block locking plates may be needed to avoid uneven block alignment, gap formation or uneven heaving due to ground water
Uniform & continuous pour/cast with ease of contour buildup	Interblock locking and trimming may be needed for block alignment
Wide range of density and strength possible (5 - 50 pcf, 2 > 500psi)	Density & strength are limited (0.6 - 2.0 pcf, 2-10 psi at 1%)

Allied Low Slump Cementitous Geofoam - easy to shape & conform to the landscape without moulds
Cast w/o Mould - Wet	Cast w/o Mould - Dry (d=25 pcf)	Mould-free Cast- Wet	Mould-free Cast - Dry (d=8 pcf)

Fiber Re-enforced Allied Cement Geofoam vs EPS Geofoam - Very Comparable Toughness During Compression

* Higher compressive strength can easily be reached by a slight density increase of Allied Cement Geofoam, e.g. 85 psi at a density of 16 pcf.

Landscape Architechture on the Roof - An application with allied low slump foam cement

HARVARD UNIVERSITY - NorthWest Science Building, 530,000 ft² multidisciplinary research facility

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.

Another example of low load pavement with Allied low density and yet high strength foam cement is shown by a recently renovated sports field on the roof of an existing gymnasium-120,000 square foot coverage with foamed cement pumped 2 stories in height and 500 feet across the entire field.
(the weight limit, compressive, shear and other performance demand and its intended use made the
project one of its kind in the US roof deck industry.)
