Abstract:
The Brazilian Standard stipulates a quality standard for ceramic roof tiles, causing many products to be discarded because they don´t match the required level, which accentuates the local environmental impact, unintentionally increasing the amount of waste. Therefore, this work aims to study the incorporation of glass waste for the future production of geopolymeric roof tiles. Reference compositions were prepared, with 10%, 20% and 30% addition of glass residue, originating from the cutting of flat glass, and subsequently the compressive strength was evaluated at 7 and 28 days. Other parameters such as consistency index, density in the hardened condition, water absorption by immersion and void index were also studied for further analysis of the geopolymer mortar. The results demonstrated that, incorporating 20% of the residue, a compressive strength of 30MPa could be achieved for a sample at a controlled temperature for 28 days. Therefore, the researched material has great potential for use, but further investigation is still needed to determine the complete efficiency of the material.
