Glass Waste Powders as Additives Based Ceramic Materials for Additive Manufacturing of Bricks

The use of recycled materialsMaterials in the field of additive manufacturingAdditive manufacturing (AM) is a solution that gives value to glass wasteGlass waste after its use in many countries, giving relief to a growing problem worldwide with the use of recyclingRecycling. This investigation shows results for the use of wasteWaste glassGlass bottles for the manufacture of bricks by the additive manufacturingAdditive manufacturing (AM) technique using additivesAdditive. Bricks of different geometry than the conventional one were produced from yellow clayClay from the city of Campos dos Goytacazes, RJ, Brazil, with the addition of 10% by weight of glass wasteGlass waste powder. With the purpose of reducing the water content in the composition, wasteWaste glassGlass powders were evaluated. Density, linear contraction, porosityPorosity, and water absorption tests were carried out to evaluate the technological properties of the materialMaterials. The characterizationCharacterization of raw materialsMaterials was also carried out by means of x-ray fluorescence (FRX), to evaluate the microstructureMicrostructure of the samples. Compression strength and dilatometryDilatometry tests for initial clayClay and clay-glassGlass mixtures were also included, detailing the behavior and various parameters of the processProcess. The production of ceramic pieces by additive manufacturingAdditive manufacturing (AM) with the addition of glassGlass residue becomes highly viable because, in addition to contributing to the development of pieces with better quality, reduces the wasteWaste environmental impactEnvironmental impact.
