Geopolymers have been recently explored as sorbents for wastewater treatment, thanks to their mechanical and chemical stability low-energy manufacturing process. One specific application could be the removal of ammonium (NH4+) through exchange with Na+ ions. Additive (AM) represents an especially interesting option fabrication, it allows tailor size, distribution, shape, interconnectivity pores, therefore access charge-bearing sites. The present study provides a proof concept NH4+ from using...
In this review, we summarize the research activities carried out by our group at University of Padova on additive manufacturing ceramics from liquid feedstocks. Particularly, evaluate use preceramic polymers, geopolymers, and sol-gel solutions. We mainly focus processing with feedstocks because they have some advantages respect to slurry-based in which powders are present. lower viscosity, enhanced transparency, lack scattering sedimentation advantageous features for vat photopolymerization...
Geopolymers can be optimized to have interesting physical characteristics, which are influenced by the raw materials and additives utilized in their formulations. For this reason, various formulations of two metakaolin-based binders with filler additions different natures, i.e., sands carbonates, were tested. The aluminosilicate source used is a commercial metakaolin (Si/Al = 1.44). feasibility consolidated samples thermal behaviors evaluated. viscosity tests fresh geopolymer pastes...
This work analyzed the effect of particle fillers on rheology geopolymer-based inks and microstructure mechanical properties lattices fabricated by Direct Ink Writing subjected to different curing firing temperatures. Adding effectively improved printability pure geopolymer ink; ground filler was most effective. In particular, it increased yield strength storage modulus, speeded up recovery after extrusion expanded working window. The response did not increase with addition nor temperature...
Volcanic ash-based on AAMs (alkali-activated materials) have been tested for the first time production of ceramics with improved thermal performances high temperature applications. Samples using sodium or potassium solutions were prepared. For set, different variations liquid/solid ratio to find optimal feasibility, evaluating in terms good workability and absence water gel surface after hardening. The results this preliminary test allowed select best formulations lower l/s ratio, namely...
