This research deals with recycling of the left over residue from processing of ornamental stones known as residue from the marble cutting process and gnaisse cutting process. The experimental program consisting in analyzing the physical and the mechanical properties of the residue and of the concrete, respectively, it will be present in that work. The tests indicate the better residue’s properties than natural sand for concrete production.   Maria Teresa Gomes Barbosa Departamento de Construção Civil Universidade Federal de Juiz de Fora Campus Universitário  Bairro Martelos Juiz de Fora – MG - Brasil CEP 36036-330 Tel.: (32) 3229-3405 E-mail: teresa.barbosa@engenharia.ufjf.br     Cláudia Valéria Gávio Coura Departamento de Construção Civil Universidade Federal de Juiz de Fora E-mail: gabiocoura@yahoo.com.br     Larissa de Oliveira Mendes Departamento de Construção Civil Universidade Federal de Juiz de Fora E-mail: larissa.mendes@engenharia.ufjf.br     Recebido em 03/07/08 Aceito em 23/12/08   A areia natural, por ser um material de grande utilização em obras de engenharia, tem sofrido um esgotamento progressivo de suas jazidas, com o conseqüente aumento de seu custo, levando à busca de soluções alternativas. No presente trabalho efetuou-se um estudo de caracterização e avaliação do emprego de rejeitos de mármore triturado e rocha de gnaisse britada, em substituição ao agregado miúdo natural, para a produção de concretos. Realizaram-se os ensaios de trabalhabilidade, resistência à compressão axial, módulo de deformação e absorção por imersão. Os resultados apontaram que os concretos elaborados com o rejeito de mármore apresentaram características mecânicas e de durabilidade superiores, comprovando a viabilidade da utilização desses rejeitos na confecção de concreto.
