Abstract EN
Geopolymer cement is the result of reaction of two materials containing aluminosilicate and concentrated alkaline solution to produce an inorganic polymer binder.
The alkali solutions are corrosive and often viscous solutions which are not user friendly, and would be difficult to use for bulk production.
This work aims to produce one-mix geopolymer mixed water that could be an alternative to Portland cement by blending with dry activator.
Sodium hydroxide (SH) was dissolved in water and added to calcium carbonate (CC) then dried at 80 C for 8 h followed by pulverization to a fixed particle size to produce the dry activator consisting of calcium hydroxide (CH), sodium carbonate (SC) and pirssonite (P).
This increases their commercial availability.
The dry activator was blended with granulated blast-furnace slag (GBFS) to produce geopolymer cement powder and by addition of water; the geopolymerization process is started.
The effect of W/C and SH/CC ratio on the physico-mechanical properties of slag pastes was studied.
The results showed that the optimum percent of activator and CC content is 4% SH and 5% CC, by the weight of slag, which give the highest physico-mechanical properties of GBFS.
The characterization of the activated slag pastes was carried out using TGA, DTG, IR spectroscopy and SEM techniques.
