Dissertação (Mestrado em Processos Construtivos e Saneamento Urbano) – Universidade Federal do Pará, Instituto de Tecnologia, Belém, 2015.https://rigalileo.itegam.org.br/handle/123456789/418The 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.pdf.Agregado graúdoConcretoBritaSeixoQuebradinhoDissertaçãoEngenharia Civil
