Item Acesso aberto (Open Access) Concreto permeável geopolimérico aplicado na pavimentação(Universidade Federal do Pará, 2023-03-07) ARAÚJO, Wendel Melo Prudêncio de; MACEDO, Alcebíades Negrão; http://lattes.cnpq.br/8313864897400179In the recent scenario, groundwater retention plays a key role in achieving environmental sustainability. This can be achieved by using pervious concrete as a paving material in roads, parking lots, garden areas and low traffic road applications. Due to its mechanical limitation, much research has been carried out to develop a more resistant material. Geopolymeric permeable concrete is synthesized by the alkaline activation of materials rich in aluminate and silica in an alkaline medium. This work aims to produce samples of geopolymer permeable concrete, using red ceramic residue and metakaolin as precursors, for application in permeable paving. The results showed that the use of red ceramic in the production of pervious geopolymer concrete up to a concentration of 30% is feasible, since higher concentrations can compromise the physical, hydraulic and mechanical properties.
