Análise do comportamento à tração por compressão diametral de solo da formação Guabirotuba com adição de cerâmica vermelha e cal

Abstract

In the face of climate emergencies, with record temperatures and extreme events affecting many people, it is essential to develop resilient infrastructures to save lives and minimize economic losses. Waste reuse is crucial in this context, mitigating environmental impacts and saving resources, aligning with the 2030 Agenda and the Sustainable Development Goals (SDGs). In the construction industry, SDG 9 (resilient infrastructures), SDG 11 (sustainable cities), and SDG 12 (sustainable production and consumption) are particularly relevant. The red ceramics industry generates significant waste, representing 7% of global production, resulting in millions of tons discarded annually. This work evaluates the tensile strength by diametral compression of soil from the Guabirotuba Formation with the addition of red ceramic waste (RCW) and lime. Samples with different waste and lime contents were analyzed, studying the influence of these mixtures and comparing the results with previous tests. The research demonstrated significant improvements in the strength of the mixtures after 28 days of curing. The results were consistent with simple compression strength tests conducted in previous research, allowing resource optimization. The use of “in situ” soil from the Guabirotuba Formation stabilized with lime and RCW reduces environmental impacts, improving the mechanical properties of the soil and providing an adequate destination for ceramic waste.
