Hot-pressed geopolymer: Dual effects of heat and curing time

摘要: Abstract Hot-pressed curing of geopolymers introduces an efficient fabrication almost pore-less and high strength binders with a minimum usage alkali activator in extremely short time. This study presents the dual effects temperature time on kinetics mechanical properties VA-based hot-pressing geopolymer. Moreover, elevated aluminosilicate precursors dissolution pressure loss hot-pressed geopolymer are investigated. It is observed that increment temperatures improves dissolving trends aluminosilicates. Furthermore, system associated liquid phase removal gelation particles; and, successive repressing mixture to initial condition reduces porosity matrix significantly. The increase key point acceleration geopolymerization kinetic, however, essential stabilization reaction.
