The aim of this study was to propose a correlation for the hydraulic parameters of pervious concrete (PC). Thus, three aggregates from civil construction waste and one basalt aggregate (reference) were used to produce PC. The ratio c/a (cement: aggre

A impermeabilização dos solos devido a urbanização vem sendo um dos grandes problemas da atualidade já que leva a uma mudança radical do ciclo hidrológico. Além disso, contribui para as enchentes, hidroplanagem e proliferação de doenças. D

To study the influence of the curing procedure polymer-modified cement mortars (PMCM) were realized in two stages. In stage 1, PMCM with different percentages of PVA (5, 10, and 15%) were produced considering two times of PVA addition in the mix (3 a

Os resultados encontrados indicam que existe uma influência direta do tipo de sedimento e da velocidade de adição do mesmo no fenômeno da colmatação do CoPe, sendo os sedimentos finos (argila) os mais prejudiciais na perda da permeabilidade do
