    CONCRETOS FABRICADOS COM AGREGADOS GRAÚDOS DISPONÍVEIS EM SANTARÉM E REGIÃO OESTE DO PARÁ
    (Universidade Federal do Pará, 2015) MAIA, Carlos Tadeu Arantes; SOUZA, Paulo Sérgio Lima
    The study examines structural concrete production using different coarse aggregates available in Santarém, analyzing fresh and hardened state properties. Gravel, pebble, and quebradinho were tested with three water/cement ratios (0.74, 0.54, and 0.41). Results showed lower water consumption with pebble and higher final strengths with gravel. A cost analysis highlighted the economic advantage of quebradinho for 20 and 30 MPa concretes. Findings support the feasibility of using local aggregates in concrete production.
