Aerlite-iX is a pure synthetic protein based preformed cellular concrete foam. Aerix Industries developed and supplies the product. CJGeo is an Aerix Industries factory-trained installer. We are based in Virginia and install cellular concrete throughout the eastern United States. Cellular concrete can be used for a variety of applications, such as:
- Lightweight fill
- Insulating fill
- Annular space grouting
- Pipe abandonment
- Tunnel & vault abandonment
Aerlite-iX Mix Designs
Aerlite is one of the most commonly used preformed cellular concrete foams in geotechnical and utility installations. It can tolerate very thick lifts, is resilient during pumping, and has high expansion during generation.
Typical densities for neat-mix cellular concrete generated range from 20 lb/cuft to 80 lb/cuft, with associated strengths ranging from 40psi to 1100psi. Sanded base mix is used to achieve higher densities, but is associated with lower strengths.
The foam generator mixes water and concentrate to a specific dilution ratio. Then, the foam generator aerates the mixture, which causes it to expand. The preformed foam doesn’t change volume after generation.
The expanded preformed foam is either:
- introduced to a transit mix truck containing a set amount of slurry (batch-generation), or
- injected inline downstream of a slurry pump (continuous generation).
Low volume pours can use batch generation. Larger volume placements require continuous generation. There are two types of continuous generation. Dry batch generation yields higher break strengths. Wet batch works best with small pours.
Aerlite-IX Applications
Heat of hydration of the cement in cellular concrete can affect the dimensional stability of the material during initial curing. Because Aerlite-iX is a synthetic protein foaming agent, it is tolerant of thicker lifts than MearlCrete or other organic protein-based preformed foams such as Aerlite (a synthetic/organic blend). Depending on density, lifts up to 20′ thick are possible.
Aerlite-iX doesn’t make pervious cellular concrete. We use Aquer-iX to generate pervious CJFill-High Permeability cellular concrete. Aquaerix creates an open cell bubble structure in the cellular concrete. This allows for permeability around 35cm/hr. MearlCrete, Aerlite and Aerlite-iX all create closed cell bubble structures within the cellular concrete, providing the lowest permeabilities possible.
