Scientific means of investigation
X-rays diffraction spectra of hardened geopolymeric materials (resins and cements) do not supply accurate information (amorphous structure). High-resolution MAS-NMR (Nuclear Magnetic Resonance) spectroscopy of 29Si and 27Al is a very powerful tool that provides useful structural data. For more updated information, see in Davidovits’ book, Geopolymer Chemistry & Applications, the Chapter 4. You may also [...]
Chemical Structure and Applications
The atomic ratio Si:Al in the poly(sialate) structure determines the properties and application fields. A low ratio Si:Al (1,2,3) initiates a 3D-Network that is very rigid. A high ratio Si:Al, higher than 15, provides polymeric character to the geopolymeric material. One third of Davidovits’ book, GEOPOLYMER Chemistry & Applications, is dedicated to applications. See the [...]
Innovation and further researches
Prof. Joseph Davidovits presents the road map for the next couple of years on geopolymer science innovation and research, at the 2nd International Congress on Ceramics, Verona, Italy, July 4th, 2008. Watch the video on Vimeo. There is a great need for innovation and therefore further research must be carried out. We have listed below [...]
