Week 5
Lecture/Recitation
Geopolymers

Lab
In lab Group 7 worked on our 3D design. Some changes to the design needed to be addressed so Group 7 filled in and rounded all the angles in the mold design.
Geopolymers
+
- inorganic material, non-crystalline network
- si-o-al framework
- amorphous - metal
- crystalline - window glass
- how to tell apart? how much light goes through
- as long as the wavelength goes through the thickness
- Flyash - based geopolymer
- alkali - activated flyash polymer
- class F flyash is typically used
- activators
- sodium hydroxide solution - very expensive - high foot print
- sodium silicate solution -re used more
- potassium silicate solution
