    A Caracterização e Resistência do Seixo Fino (Quebradinho) no Município de Santarém - PA
    (Universidade Federal do Pará, 2015) QUEMEL, Laise Deanne Figueira; PICANÇO, Marcelo de Souza
    Civil construction works in Santarém have been using a coarse aggregate popularly called 'quebradinho' in structural concrete. This work aimed to study the resistance of the 'quebradinho' or 'gravel' in natura and washed, proving its efficiency as an aggregate for concrete in buildings and reducing construction costs in the region. Using the ABCP method for resistance proof, the results of physical characterization and mechanical properties of concrete dosed with such aggregates were shown. All molded specimens presented satisfactory results within the compressive strength standards between the 3rd and 28th days. It is concluded that the use of quebradinho is economically viable and effective, although further studies on water absorption and durability are needed.
