Influence of the Mixing Processes of the Constituents of Incorporated Geopolymer Materials with Glass Waste

摘要

During the production of geopolymeric materials a great challenge exists when it comes to the process of dosing and mixing the constituents, called activators and precursors. In addition, these materials have a great potential for incorporating different solid waste. The objective of this work was to evaluate the different ways of mixing the constituents of the geopolymer materials, evaluating the influence of these variations in the mixing process, molding and curing temperature of the mixtures, and incorporating the glass waste as an activator of the mixture with a molar ratio of 3.5. Prismatic specimens were made and properties such as mechanical resistance to flexion, linear shrinkage, and water absorption were evaluated for each condition evaluated. It can be concluded that the order of insertion of the components in the mixture, as well as the molding mode and cure temperature directly influence the technological properties of the specimens.
