Members of the SICon research group participated in the publication of an article in the “Journal of Building Engineering” in collaboration with researchers from UENF and UFF.
The article is entitled: “Potential use of ceramic waste as precursor in the geopolymerization reaction for the production of ceramic roof tiles” and is part of the volume 29 of the May 2020 issue of the “Journal of Building Engineering”.
The authors of the article are: Afonso Rangel Garcez de Azevedo, Carlos Maurício Fontes Vieira, W.M. Ferreira, Kátia Cristina P. Faria, Leonardo Gonçalves Pedroti, Beatryz Cardoso Mendes.The group is composed of researchers from Universidade Estadual do Norte Fluminense Darcy Ribeiro (UENF), Universidade Federal de Viçosa (UFV), and Universidade Federal Fluminense (UFF).
The experimental program comprised of chemical characterization, particle size analysis, X-ray diffraction, real specific grain mass, pozzolanic activity index (PAI) and Scanning Electron Microscopy (SEM) of the ceramic waste (chamotte or grog) in order to evaluate its potential to replace metakaolin as a precursor agent in the production of geopolymers. This study also aimed to assess the technological performance of the geopolymeric products and the viability of their application in the production of ceramic roof tiles comparing two manufacturing processes: molding and pressing.
