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 tow

We investigated a novel processing technique of municipal solid waste incineration (MSWI) ashes. By using two thermodynamic driving forces - a strong alkaline activator and a compaction pressure, the otherwise relatively nonreactive MSWI ashes could

In a recent study, we developed ultralow-binder-content (UBC) structural materials based on lunar soil simulant and thermoset binders. In the current research, we investigated thermoplastic binders. Compared to thermosets, advanced thermoplastics cou

Strong structural materials were produced by using JSC-1a lunar soil simulant, with only 4 wt% epoxy binder. The flexural strength reached 12–16 MPa, comparable with typical steel-reinforced concrete. The processing mainly involved dropping a hamme

In order to reduce the use of class F fly ash in geopolymer parts, we investigated the compaction self-assembly (CSA) technology, which could greatly decrease the fly ash content from ~ 25 to ~ 10 wt%. In CSA, a compaction pressure was applied on the
