State of the Geopolymer R&D 2012

It is a review on what happened in 2011 and the first semester of 2012 on geopolymer science and applications. In his keynote, Prof. J. Davidovits developed following topics:

1) Geopolymer science

  • Geopolymer Conferences
  • Exponential increase of laboratories and scientific publications
  • Book “Geopolymer Chemistry & Applications” 3rd edition and Chinese edition
  • Geopolymer Terminology vs Cement Terminology: Na-S-Al-H cement-like terminology is an obstacle to fostering innovation
  • 2 new geopolymer molecular units
  • Al-O-P-O- poly(alumino-phospho) AlPO4-based geopolymer
  • Fe-O-Si-O-Al-O-Si-O- poly(ferro-sialate) (Mössbauer spectroscopy)

2) Geopolymer technologies

  • Pharmaceutical applications of geopolymer pellets
  • Thermostructural fibrous geopolymer composite
  • Heated mold for molding organic fibrous composites (15 meters long)
  • Coatings and adhesives comprising synthetic geopolymer-epoxy compositions
  • Geopolymer binder for recycling waste rockwool, reforming lava spuns into fibers
  • Fire rated Aluminum-geopolymer panels
  • BASF / PCI geopolymer grout launched in Europe
  • First geopolymer binder based on “waterglass” manufactured by waterglass industry

3) Geopolymer Cements / Concretes

  • Paving tiles based on steel slag/geopolymer mass-produced in India
  • 2012 Rio de Janeiro Summit: CO2 increase
  • Costs and carbon emission for geopolymer pastes in comparison to OPC, Australian context
  • Why establish 2 universal and user-friendly geopolymer cements, standards for global economy?
  • 1) (Na,K,Ca)-fly ash-based geopolymer cement
  • 2) (Na,K,Ca)-(ferro-sialate)-based geopolymer cement
  • 3) indusctrial hardener in powder form based on geology

4/ Geopolymer and archaeology

  • Latest analysis of geopolymer stone (Snefru’s Bent Pyramid)
  • Projects on “stand-by” due to polutical situation in Egypt
