OLIVEIRA, Dênio Ramam Carvalho de2025-03-172015https://rigalileo.itegam.org.br/handle/123456789/733Natural fine aggregates are widely used in construction for the production of mortars and concretes. This study analyzed the behavior of fine aggregate from Laranjal do Jari-AP, comparing it with the traditional fine aggregate from the metropolitan region of Belém-PA. Physical, mechanical, and durability tests were conducted following ABNT standards. The results showed that the aggregate from Laranjal do Jari-AP exhibited higher compressive and tensile strength, in addition to meeting durability standards, demonstrating potential for use in mortars in civil construction.ArgamassaAgregado miúdoConstrução civilResistência mecânicaDurabilidadepdf.Engenharia Civil e Materiais de Construção
