Impact self-assembly of low-binder-content geopolymer parts

In the current study, we produce low-binder-content geopolymer parts through impact self-assembly. After sand (the filler) and a small amount of fly ash-alkaline activator mixture (the binder) are premixed, they are impacted by a hammer in a drop tower. The hammer mass is around 2∼5 kg and the drop...
