| Abstract Scope |
Studies using the geopolymerization process of the brick wastes from civil construction in the production of new materials, with characteristics and properties similar to traditional ceramics, has been growing in the recent years. The present work used these brick wastes as precursor material and Na2SiO3 (alkaline sodium silicate) and KOH (potassium hydroxide) as alkaline activators on the geopolymer dosages, where the blend was determined with the molar ratio SiO2/Al2O3 equal to 4.0. The molded and pressed specimens were left to mature at room temperature and at 60°C during 7 and 14 days. Afterwards, they were submitted to the flexural strength, linear shrinkage, water absorption and apparent porosity tests. The results showed that, the longer the cure time, the better the technological characteristics of the specimens, both at room and controlled temperature. Thus, it was verified that the brick wastes are an interesting alternative as binder in the production of geopolymeric ceramics. |
