“…Fakitsas et al regarded that the reason for these findings was due to the water absorption of the RA when it was submerged in water. Ranjbar et al and Gesoglu et al reported high water absorption characteristics of RAs compared with natural aggregates. As a result, the saturating treatment and a maximum replacement at 30% for RA were suggested in SCC.…”

“…For years now researchers have been studying the impact of the amount of added crushed recycled aggregate on concrete strength. Results compiled and presented in studies [14,21,[27][28][29][30][31][32] do not provide an unequivocal assessment of the impact exerted by cullet on concrete strength. Researchers argue that as the contents of recyclate are increased, the compressive strength of concrete tends to drop.…”

“…Nesse sentido, a relação resistência à tração/compressão dos concretos com agregados reciclados do presente estudo variou entre 9,70% à 10,58%, e o concreto referência apresentou relação igual a 11,21%. De mesmo modo, [26,28] notaram diminuição na resistência à tração em concretos autoadensáveis produzidos com agregados reciclados. O módulo de elasticidade do concreto é dependente do módulo de elasticidade dos agregados utilizados.…”

“…No entanto, não foi encontrada uma relação clara entre o percentual de incorporação e a redução desta propriedade das composições estudadas. [28] relataram diminuição do módulo de elasticidade, entre 13,12% a 18,42%, dos concretos autoadensáveis produzidos com emprego total de agregados graúdos reciclados. E semelhantamente, [29] observou a redução de 13,71% desta propriedade em composições onde houve substituição do agregado graúdo natural pelo reciclado, na proporção de 20%.…”
