Advantages of Cellular Concrete

 

High Strength/Low Density/Lightweight
Typical cast densities range from 25 to 55 per cubic foot, with compressive strengths of 40 to 750 psi, respectively. With its low density, cellular concrete imposes little vertical stress on the substructure, a particularly important issue in areas sensitive to settlement.  Due to its low density, cellular concrete is a viable solution for reducing loading on burdened soil.  Additionally, cellular concrete is less susceptible to differential settlement.  Heavier density cellular concrete with higher strengths is produced and used for specialty applications.

 

No Compaction Required
In some cases mechanical compaction can be difficult and unsafe due to limited or inaccessible areas.  In excavations with poor soils that are not easily or incapable of being compacted, cellular concrete forms a 100% compacted foundation over the soft soils.  When compaction of conventional backfill against retaining structures or deep foundations, traditional methods can cause damage or movement to the adjacent structure or just be too time consuming.  In these instances, cellular concrete is a great solution.

 

High Fluidity
High air content makes it easy to pump materials long distances at low pressures.  The material is naturally self-leveling and fills the smallest voids, cavities, and seams.  When placing in excavations cellular concrete conforms to every sub grade contour.

 

Rapid Installation
High volume production and placement (via hose) of cellular concrete is a continuous operation from a mobile central plant on location.  Since the foam is the largest volume contributor in cellular concrete, limited deliveries of the raw materials are required, resulting in minimal disruption to the construction site.

 

Settlement Free Construction
The principle of equilibrium and the use of cellular concrete aims for settlement-free construction. When higher density soils are excavated, they are replaced with cellular concrete, so that the combined weight of the cellular concrete and the new construction is less than or equal to the weight of the removed soil.  Thus the effective stress of the underlying soil has not changed, preventing settlements.

 

Reduced Sound Transmission

When used in roof deck, flooring, cast-in-place walls, floors or roofs, block or per-fabricated elements, fir or partition wall applications, or as cavity fill for vehicles, the void structure of cellular concrete reduces the passage of sound.

 

Ease of Removal
Cellular concrete can be designed for specific strengths to allow for future removal for maintenance of utilities or excavation.  Sometimes excavation of flowable fill materials can be difficult due to unpredictable gains in strength due to delivery and production methods.  Cellular concrete is produced on location to exact requirements, and can be easily excavated with common construction equipment.

 

Thermal Insulation

Cellular concrete provides good insulating qualities.  It is thermally efficient and is an unmoving insulation material which maintains long term in-place stability for a variety of construction and industrial applications.  This low to medium density cement material is highly flowable in its initial state allowing for easy placement and complete filling of formed spaces of any shape or configuration.  Cellular concrete mixes harden to provide a material with proven high temperature resistant characteristics which permit it to be used as a fire resistant material.  It is also environmentally safe and non-polluting.

 

Provides Shock & Energy Absorption

Used beneath roadways, bridges, and ramps, buildings and other structures, it reduces soil loading while adding compressive and shear strength.   As cellular concrete is compressed during impact, resistance increases and kinetic energy is absorbed.   In America and Japan in particular, contractors and engineers frequently use cellular lightweight concrete provide shock absorption in earthquake zones.

 

Recyclable

Cellular concrete is inert and can be safely removed and reused.  Once green use of recycled concrete is as aggregate in vegetated roof construction (green rooftops). 

 

Recycled Content

Cellular concrete can incorporate ground granulated blast-furnace slag or fly ash in the slurry or grout mix design without adversely affecting cellular concrete performance.  The use of these post-industrial byproducts eliminates the need to landfill the materials and reduces the need for virgin materials in cellular concrete production and the environmental impacts from the extraction and processing of these virgin materials.

 

More Flexibility For Specific Construction Challenges
Cellular concrete can be constructed into various formations and profiles.  It can be produced as a non-permeable or a permeable material capable of reducing loads without disturbing or re-directing natural water flow.  It also forms a rigid, well-bonded body after
hydrating; thus, it is effectively a freestanding structure on its own and does not impose lateral loads on adjacent structures.

 

Pervious to Water

Cellular concrete is optimal for applications where drainage is needed.  It is capable of reducing loads without disrupting or redirecting the natural flow of water.
