Product Summary

The information below summarizes many aspects of the CoreTech cellular concrete technology:

Product Summary – CoreTech Cellular Concrete

  • A unique lightweight concrete with air cells uniformly distributed throughout the material
  • Produced through a proprietary chemical, mechanical, and blending technology
  • Can utilize the mixture of other materials such as polymers, crumb rubber, fibers, fly ash, or perlite for special applications requiring enhanced fluxural, thermal, or weight specific properties
  • Maintains load-bearing capability, resists water / wind / fire weather elements, capable of modification with common hand tools, is a “green” technology, and is a lower cost methodology compared to traditional construction techniques


CoreTech Cellular Wall Panels

  • CoreTech Wall Panels are composed of traditional metal framing which is embedded in a cast of cellular concrete.
  • The panels can be cast with exterior and interior molds to look like brick, stucco, wood, drywall, or any fascia desired.
  • Each panel is manufactured to specification for its particular placement and configuration within a building plan.
  • The casting process is done in a controlled manufacturing environment to ensure high quality standards are met.
  • A proprietary form system allows for multiple wall panels to be cast simultaneously.
  • Each panel is tracked through production to delivery to the building site.
  • Panels are erected with tilt-up methods and joined at the building site.
  • Time & money savings through elimination of traditional construction labor and material costs such as framing, house wrap, masonry, insulation, and drywall


CoreTech’s Commitment to the Environment

  • Creating timber-free products reduces reliance on clear cutting of forests or imports of foreign produced timber.
  • Utilizing little or no aggregates in our products decreases the overall demand for the mining and transport of sand or gravel.
  • Advanced applications of our products utilize recyclable resources such as crumb rubber or fibers found in waste products such as old tires.
  • CoreTech’s production techniques can utilize recycled water to reduce reliance on local water supplies.
  • Unusable or rejected manufactured cellular product can be crushed and reused to make new product.


CoreTech’s Fly Ash Usage

  • Fly ash is a waste product of coal burning electrical plants that is normally dumped into the environment or landfills.
  • Using fly ash as a component of cellular concrete reduces the effects of energy waste on the environment.
  • The composition of fly ash is highly suitable for its usage as an admixture to cellular concrete.
  • Fly ash is non-corrosive to metals and reduces water permeability of concrete.
  • Fly ash can replace as much as 65% of the Portland cement mixture used in cellular concrete depending upon the application specs of the end product.


Fly Ash Use Equations

Assuming a compatible ash from a coal fired plant with a standard type of mix design:

28 lbs cement per cubic foot of cellular concrete
50% (by weight) replacement of cement with ash
32 cubic feet of cellular concrete in a standard 8' X 8' panel
800 maximum panels per day in a production CoreTech plant
= 28 X 0.5 X 32 X 800 = 358,400 lbs
= 179.2 tons maximum daily fly ash consumption


Note that several factors can affect the actual consumption rate including such items as smaller closure panels, adjustments in mix design, etc.  However, a 50% ash usage per pound of cellular concrete product is a reliable and conservative estimate for most applications.

CoreTech Wall Panels vs. Brick

  • Current usage of fly ash in concrete is predominantly in brick products.
  • CoreTech’s wall panel systems provide a superior approach toward construction that reduces labor costs and increases material strength over and above brick construction methods.
  • CoreTech’s controlled manufacturing environment for cellular concrete wall panels assures the uniformity of panels and reduces labor mistakes in construction.
  • Tilt-up wall methodology is already in wide usage for commercial construction and is far more accurate than brick construction methods.
