Cimento Portland, terra diatomácea, resíduo sólido, filtragem , SilícioResumo
O potencial da terra diatomácea como um resíduo aproveitável, proveniente de processos de filtragem, se dá devido ao seu alto teor de silício e morfologia favorável para reações químicas. Sua granulometria refinada e estrutura amorfa indicam alta reatividade. Deste modo, foi explorada a aplicação deste resíduo como substituto parcial ao cimento Portland, visando obter um material com propriedades mecânicas, boa durabilidade e menores impactos ambientais associados à destinação de resíduos e à emissão de CO2. A dosagem da argamassa foi realizada substituindo o cimento Portland por até 25% de resíduo diatomáceo. Ensaios de resistência à compressão e absorção de água foram realizados nos corpos de prova moldados com o traço estabelecido, comparando seu desempenho com o do cimento Portland puro. O material desenvolvido ficou próximo do limite normativo para cimentos de classe 32, ficando apenas 5% abaixo do exigido. Esse resultado demonstra o enorme potencial da utilização de resíduos na produção de materiais cimentícios sustentáveis, reforçando a viabilidade técnica e a promessa de um futuro mais verde e inovador para a construção civil.
