Concreto impregnado com polímero (CIP): uso e aplicação do EPS reciclado para redução da permeabilidade de superfícies de concreto

Abstract: A redução da porosidade, e conseqüente redução da permeabilidade, pode ser uma solução para aumentar a durabilidade do concreto e preservar suas características superficiais. Dentro desse contexto, esta pesquisa foi desenvolvida com o objetivo de identificar um novo material a ser aplicado no sistema CIP (Concreto Impregnado com Polímero) de forma econômica, eficiente e com simplicidade, a fim de reduzir a permeabilidade das superfícies de concreto pré-fabricado. Adicionalmente: a) empregar um tratamento que n… Show more

“…It can be seen in the micrographs the deposition of sulfonated polystyrene in the form of lamellae, and the presence of polymeric film (SPS) on the microstructure of the modified mortars. As the admixture content increased, modification in the microstructure of the polymeric film was observed in the mortars, from a lamellar structure to the more continuous polymeric film [33], as shown in Figures 10c-10e. In Figure 10c, it is possible to identify both types of polymer structures: lamellar structures in the center of the micrograph and continuous film to the right, indicated by the arrow.…”
