| Abstract Scope |
Geopolymeric materials have been widely studied due to technological and environmental advantages, which in the case of applications in ceramic materials is due to the non-need for sintering the parts. The objective of this work was to evaluate the potential of using the glass polishing residue as a constituent element of the activating solution, together with NaOH, in geopolymerization reactions, aiming at the production of ceramic artifacts. Specimens were submitted with thermal curing at 60 ºC and ambient temperature of 23 ºC with in ratio to SiO2/ Al2O3 of 3 and 4. Were evaluated of technological properties such as apparent specific mass, linear shrinkage, water absorption and mechanical resistance to flexion in the specimens. The results showed a potential for application of the glass polishing residue as a component of the alkaline solution, improving the properties evaluated when in thermal curing and with a SiO2/ Al2O3 ratio of 4.0. |
