Materials | Powder | Liquid |
---|---|---|
CPC without macropores | CPC powder | Water |
CPC–sodium phosphate without macropores | CPC powder | Sodium phosphate solutiona |
CPC–sodium phosphate with macropores | CPC powder+mannitolb | Sodium phosphate solutiona |
CPC–chitosan with macropores | CPC powder+mannitolb | Chitosan solutionc |
This was a 0.75 mol/L sodium phosphate solution (Abbott Laboratories, North Chicago, IL) to cause fast-setting to the cement.
Mannitol was a porogen that was used to create macropores in CPC. The mannitol/(CPC powder+mannitol) mass fraction M was fixed at 0.4 for Group 1.
Chitosan biopolymer was used to cause fast-setting and strengthening to the cement. The chitosan/(chitosan+water) mass fraction = 15%.
