Geofill Cellular Concrete products are lightweight materials produced by blending a cementitious slurry with a stable, three-dimensional pre-formed foam meeting ASTM C869. The foam is produced by diluting a liquid concentrate with water, then pressurizing it with air and forcing it through a conditioning nozzle. The foam is then blended with a base mix consisting of cement, fly ash, water and sometimes aggregate. This causes the base mix to expand and become lighter. The air bubbles hold their shape until the cement hydrates permanently trapping the air in the material. The density and strength of the material is a function of the mix design. While specific Geofill product performance characteristics will vary, all Geofill cellular concrete products offer these substantial benefits:
Low Density/Lightweight - Lateral or vertical
load reduction can be achieved without
reducing strength or stability. Densities range
from 15 to 120 pounds per cubic foot.
Non-Permeable or Permeable - More flexibility
to solve specific construction challenges.
High Bearing Capacity - Lightweight, yet
stronger than soils or compacted fills.
Extremely Pumpable - High air content makes
it easy to pump Geofill materials long distances
at low pressures.
Highly Flowable - Self-leveling and will flow into
and fill any void.
Compaction - No compaction is necessary.
Use this product when future settlement
cannot be tolerated.
Thermal Insulating Properties - Provides good
Energy Absorbing - As cellular concrete is
compressed during impact, resistance increases
and kinetic energy is absorbed.
Geofill LD Pervious
Geofill LD Pervious is the latest advancement in low density cellular concrete. This engineered, open-cell lightweight material is capable of reducing loads without disturbing or re-directing natural water flow.
Ideal for applications where drainage is needed in combination with a lightweight material, Geofill LD Pervious is available in densities/strengths ranging from 20 to 30 PCF and 50 to 200 PSI.
