Construction materials for sustainable development

Our Geopolymer Concrete cures faster than ordinary Portland concrete – 5 days vs. 28 days, respectively, leading to significant construction cost savings. For a typical commercial project such as a 10-story condo-hotel in Orlando, FL, a $68.6M project, accelerated curing leads to estimated savings of $11.9M, calculated only on the basis of reduced labor costs and construction loan interest.

Our proprietary Geopolymer formulations are based on inexpensive low-quality industrial by-product materials such as fly ash, blast furnace slag, silica fume, etc. The actual choice of source materials depends on factors such as availability, cost, and specific demand end user demand. In addition, the Geopolymer Concrete is lightweight. These conditions lead to material costs savings as high as 45-50% comparing to ordinary Portland concrete, depending on local market conditions.

Construction Applications

  • Geopolymer Concrete
  • Bricks, Tiles, Decorative Structures
  • Mortars, Sealants, Binders
  • Fire-Resistant Panels/Walls
  • Structural & Thermal Reinforcement

Geopolymer Concrete

Geopolymers replace Portland cement
  • Superior mechanical properties.
  • Chemical resistance (acids, toxic waste, salty water).
  • Fire resistance & thermal insulation.
  • Shorter time to max. strength.
  • Impervious.
  • Good abrasion resistance.
  • Low specific creep and drying shrinkage.
  • Excellent resistance to freeze-thaw cycles.
  • Competitive costs.

Toxic Waste Management

  • Toxic waste encapsulation and stabilization
  • Landfill capping and/or base liners
  • Mine tailings: Pipes, Reservoirs, Leaching Pads

Geopolymer Concrete Types

Same types as Portland cement-based concrete are possible:
  • Ready-mixed
  • Pre-cast
  • Pre-stressed
  • Pumped
  • Cellular

Infrastructure Applications

  • Marine applications: Superior chemical resistance
  • Sewage Pipes: Superior chemical resistance
  • Very high strength applications: Bridges, columns, piers and dams.
  • Very early strength concrete for fast repairs
    • Full-depth pavement patches
    • Short stretches of new pavement
    • Bridge decks, overlays
  • Soil stabilization
