THE CHARACTERIZATION OF THE Ca-K GEOPOLYMER/SOLIDIFIED FLUID FLY-ASH INTERLAYER
A Ca-K geopolymer matrix based on clay material and blast-furnace slag was filled with aggregates, ash pellets made from fluid fly ash, and the interlayer formed between the two components was studied. The scanning electron-microscopy investigation of the inseparable interlayer demonstrated that the...
