ACOUSTIC CEMENT BOARD, WATER PERMEABLE FOAMED CEMENT

The world's first foamed cement and concrete with control of % Open POREs vs Close POREs

* economical porous material for all weather acoustic panels *

(highway, mine, tunnel, railroad, mass transit, power plant, subway, marine vessel, airport, heat pump)

Allied Foam Tech has developed the world's first foamed cement and concrete with total control of % "open pores vs close pores" and a precise engineering of the various degrees of water permeation of the foamed cementitious composites for acoustic panels, retaining walls, road pavement, void fills and water purification/filtration discs.

The water permeability of conventional pervious foamed or unfoamed concrete systems rely heavily on the gaps among the coarse/loose packed aggregates, very coarse and open foam bubbles or the interconnecting capillaries derived from extensively coalesced or collapsed foam bubbles in the foam cement matrix. In contrast, the fine pore size, spherical shape, and high compressive strength of Allied Foam Tech foamed cement and concrete of various degrees of water permeation are indistinguishable from one another, even their degrees of close pores vs. open pores are very different.
Allied chemically engineered open and closed pore properties within their cell structure are very similar to that of urethane and polystyrene foams, but without their associated poor fire resistance, yet with outdoor durability and great cost advantage.

Such foamed 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.
