Resumo

O objetivo do presente estudo é avaliar as propriedades físicas e mecânicas do concreto com resíduos de borracha de pneus (RCN) como substituto parcial da areia, considerando os materiais locais da cidade de Cochabamba, Bolívia, com o intuito de promover uma economia circular. Para este fim, a areia foi substituída por RCN (por volume) em quatro porcentagens: 0% (referência), 5%, 10% e 20%, avaliando suas propriedades mecânicas (resistência à compressão, à tração e à flexão) e propriedades físicas (massa específica, absorção de água e relação de vazios). Os resultados indicam que há uma tendência à diminuição com uma maior porcentagem de RCN tanto para a resistência mecânica quanto para as propriedades físicas, com exceção da mistura de 5% de RCN, que mostrou resultados comparáveis ao concreto com areia natural. O RCN pode ser usado na produção local de concreto até 5% sem comprometer suas propriedades mecânicas e físicas e proporciona uma abordagem sustentável.
