STUDY AND PHYSICAL CHARACTERIZATION OF SOIL-CEMENT BRICKS USING TONER POWDER WASTE|可持续建筑材料数据集|工业废物管理数据集

Soil-cement bricks are a sustainable alternative in civil construction due to their efficient physical-mechanical properties, using soil, cement and water in pre-defined proportions. Studies have been developed with the aim of incorporating new materials into their composition, resulting in better properties compared to conventional bricks currently on the market. Thousands of toner cartridges are discarded daily in landfills and, due to their significant amounts of non-biodegradable and polluting toner powder, they generate a global problem that has challenged researchers. This study evaluated the combination of soil-cement bricks produced with toner powder waste, aiming to find an ecologically acceptable solution for this material and also to boost sustainability in civil construction. Through analyses of each material used and a careful review of the literature, bricks were developed with 3% toner powder waste in their composition. After curing the samples, the bricks were subjected to mechanical compressive strength tests, revealing values significantly higher than the minimum requirements established by Brazilian standards. The results demonstrated the technical feasibility of using toner powder residue in the production of soil-cement bricks, and its relevance for the sustainable management of industrial waste, with the promotion of more sustainable practices in civil construction.

土壤水泥砖因其高效的物理力学性能，在土木工程领域成为一种可持续的替代材料，其通过按照既定比例混合土壤、水泥和水制成。为了将新型材料融入其组成，提升其性能，相较于市场上现有的传统砖块，研究人员已开展了一系列研究。日复一日，成千上万的硒鼓墨盒被丢弃在垃圾填埋场，由于其中含有大量的不可降解且污染性的墨粉，这一现象引发了全球性的问题，对研究者构成了挑战。本研究评估了利用硒鼓墨粉废弃物生产的土壤水泥砖的组合，旨在为这种材料找到一种生态可接受的解决方案，并促进土木工程领域的可持续发展。通过对所用材料的分析以及文献的细致审查，研发出了含有3%硒鼓墨粉废弃物的砖块。经过养护后，这些砖块接受了机械抗压强度测试，结果显示其值显著高于巴西标准所规定的最低要求。研究结果表明，在土壤水泥砖的生产中利用硒鼓墨粉残留物具有技术可行性，且对工业废弃物的可持续管理具有重要意义，有助于推动土木工程领域更加可持续的实践。
