More Information About Foamed Concrete
DENSITY & STRENGTH
Porofoam can be tailored to your requirements, our technical team will create a suitable mix design for your application. Porofoam can achieve strengths of up to 20 N/mm2and our unique production process allows us to produce an extremely wide range of dry densities from as low as 300kg/m3 up to 2000kg/m3. For strengths and densities outside of this range our team will work with you to provide a solution.
FOAM CONCRETE PLACEMENT GUIDANCE
Porofoam can be pumped, horizontally, vertically, or directly placed in layers of up to 1m single lift depth in order to maintain the required air void structure. The fluid nature of Porofoam allows the concrete to free flow into even the smallest of spaces making it highly suitable for voidfill applications. Porofoam can be pumped by either a conventional concrete pump or rotor stator pump. The material typically remains fluid for 2/3 hours after mixing with the foam (dependent upon ambient conditions). Porofoam also exhibits no settlement characteristics that may occur with granular fill materials allowing a much more stable fill.
Porofoam foamed concrete can be supplied with or without coarse aggregate depending on the type and application. The stable bubble structure can be introduced into the mix in three ways:
By blending a pre-formed foam into a mortar base mix after mixing or at site, enabling the achievement of ultra low densities.
By adding specially formulated air-entrained admixtures into the concrete during the mixing process. This generally produces an entrained air content of between 10% and 25%. The resultant material is referred to as High Air-entrained Concrete (HAC) or High Air-entrained Mortar (HAM)
By adding foam generating admixtures to a mortar base mix after mixing or at site. This will produce higher levels of entrained air than air-entraining admixture and consequently a lower density.
