Exhaustive research has gone into producing a viable alternative to Portland cement. Over 4,000 experiments using hundreds of different ingredients have been tested over several years on a quest to design mixtures that would outperform and outlast traditional concrete.We have discovered that materials consisting of Class C fly ash and ground granulated blast-furnace slag (GGBS) increase strength significantly, reaching levels as high as 20,000 pounds per square inch.

Geopolymer Concrete VS Portland Cement Concrete

Geopolymer Concrete

  • Resistance to freeze and thaw cycling Freeze and Thaw
  • High chemical resistance Acid Resistance
  • Strength development time can be greatly reduced. The ultimate strength can be achieved within about 2 hours using electrical treatment, 4 to 6 hours using heat and 28 days with normal curing
  • Supports an insulating R-value as high as 8 per inch of material when cellular mixtures are utilized
  • Dynamic and designer selected modulus properties Modulus
  • Faster or slower set times, which are operator determined Time of Set
  • Has an extremely low air and water permeability (unless a permeable mixture is requested) RCP
  • Withstands extreme heat without degradation
  • Volume change (shrinkage) is reduced to a negligible amount Shrinkage

Portland Cement Concrete

  • Susceptible to freeze and thaw cycling
  • Susceptible to low pH material attack
  • Limited methods to expedite strength development
  • Limited insulating properties
  • Typical and difficult to change modulus properties
  • Limited set times
  • Some control on permeability
  • Extreme age degradation and carbonation when heated
  • Volume change is difficult to control with ASTM specifications
