“…Similar conclusions have been demonstrated by Fu et al [16] and Hou et al [13]. Further, the effect of fiber polymer on the damping property of cement-based materials has been reported by Jeon et al [17]. However, the results indicated that the addition of a polymer emulsion could significantly reduce the mechanical properties of cement-based materials [10,18], which limits the applications of polymer emulsion in improving the damping property of cement-based materials.…”

“…Compared with the cement mortar modified with 30% SEA, the compressive strength of the specimens with addition of 0.25%, 0.5%, and 1% fiber increased by 0.4%, 5.5%, and 8.7%, respectively, after 28 days curing. This is mainly due to the polypropylene fiber plays a "bridge joint" role in the cement mortar [17], which can connect dispersive SEA to exert the function of synergies. It can also effectively prevent the extension of cracks in the cement mortar and enhance the compressive strength of the cement mortar.…”

This study proposes a new cement mortar incorporating damping aggregate (DA) and investigates the mechanical properties and damping property of the cement mortar. Four types of DA were prepared, lightweight aggregate presaturated water and three types of polymer emulsion. Further, the effects of polypropylene fiber and rubber powder on the performance of the cement mortar were studied. The experimental results showed that the damping ratio of specimens containing 70% DA was approximately three times higher than that of the reference mortar, with a slight decrease in the mechanical properties. Adding fiber was more effective than rubber powder in improving the damping ratio of the cement mortar, and the optimal dosage of fiber was 0.5%.

In this study, recycled aggregate concrete (RAC) modified with polypropylene fiber (PP) and air-entraining agent (AGA) was prepared, and the effects of PP and AGA on the static (compressive strength, Young’s modulus, and splitting tensile strength) and dynamic properties (dynamic modulus of elasticity and damping ratio) of RAC were investigated. The experimental results showed that the addition of an AGA and PP had a favorable effect on the damping ratio of the concrete, however, the addition of the AGA had a slightly negative effect on the mechanical performance of the concrete. The AGA and PP contents required to achieve the optimum damping ratio of the concrete with the least reduction in the mechanical performance were 0.02% and 0.10%, respectively. Furthermore, the addition of AGA was more effective than that of PP in improving the damping property of the concrete.

“…O Concreto Polimérico (CP) é um material compósito feito de agregados minerais como areia e cascalho em combinação com um polímero que detém a função de substituir total ou parcialmente o aglutinante tradicional de Cimento Portland na mistura [2][3][4][5][6]. O CP pode ter suas características mecânicas aprimoradas com a adição de nanofillers ou utilização de fibras (sintéticas ou naturais), nesse caso, recebe o nome de Concreto Polimérico Fibro-Reforçado (CPFR) [3,6,[7][8][9][10][11][12]. A alta permeabilidade, baixa resistência à abrasão, baixa resistência ao ciclo gelo degelo, longo tempo de cura e fenômenos como carbonatação e ataque por íons de cloro, são algumas das desvantagens apresentadas pelo concreto tradicional [13][14][15].…”

Resumo: Este artigo apresenta uma revisão sistemática sobre o uso de concreto polimérico reforçado com fibras sintéticas na construção civil, com intuito de aprimorar o conhecimento sobre o tema e fomentar futuras pesquisas. Definidas as perguntas norteadoras do trabalho, deu-se início ao processo de busca por meio da criação de filtros, estratégias de coleta e critérios de exclusão pré-estabelecidos. Os resultados apontaram escassez de estudos relacionados com a aplicação de fibras sintéticas em Concretos Poliméricos. As matrizes poliméricas compostas por resinas epóxi e os reforços sintéticos de fibras de vidro foram os materiais mais empregados no desenvolvimento de pesquisas. A Coreia do Sul juntamente com a China e Portugal, foram os países que apresentaram maior número de pesquisas. O emprego no reparo de rodovias e a eficiência no combate de vibrações sísmicas, foram os assuntos mais comumente estudados pelos pesquisadores. O artigo sugere realização de estudos que empreguem resíduos industriais como reforços sintéticos com objetivo de diminuir custos produtivos e viabilidade no emprego do material em maior escala, além de futuros trabalhos envolvendo Prospecções Tecnológicas.
