Four experimental mixtures were developed: two using Portland cement CP II-F 32 and two with geopolymeric matrices activated by sodium hydroxide and sodium silicate solutions. The aggregates used were coarse crushed stones of two sizes (b0 and b1), in addition to 5% of fine sand in the conventional mixes. Compressive strength, splitting tensile strength, and permeability tests were conducted according to ABNT standards. The results showed that geopolymeric concretes achieved higher compressive strength, reaching 19.2 MPa for the mix with smaller aggregate, while conventional concretes did not exceed 6.3 MPa. Regarding tensile strength, the geopolymeric mixtures also performed better, indicating improved bonding between the matrix and aggregates. As for permeability, all mixtures met the requirements established by NBR 16416 (k > 1 mm/s), with the conventional concrete containing coarse aggregate b1 exhibiting the highest permeability coefficient—about 13% higher than the corresponding geopolymer mixture. It is concluded that the use of geopolymeric binder, in addition to reducing environmental impact through lower CO₂ emissions, provides higher strength concrete while maintaining adequate permeability for light-traffic pavement applications.Acesso AbertoConcreto permeávelGeopolímeroConcreto convencionalPervious concreteGeopolymerConventional concrete.CNPQ::ENGENHARIAS::ENGENHARIA CIVILTrabalho de Curso - Graduação - MonografiaAttribution-NonCommercial-NoDerivs 3.0 Brazil
