“…The experimental results show that the porosity varied from 19.1 to 28.6%, whereas the permeability varied from 4.3 to 15.3mm/s. Both parameters presented the same tendency: increases in porosity entailed a higher permeability agreeing with the results found in the literature [14,46]. Besides, in order to analyze how the type of aggregate influences the results, a significance analysis using the ANOVA software was carried out.…”

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: aggregate) 1:3.26 and a w/c ratio of 0.34 were used in all mixtures. Compressive and flexure tensile strength tests were performed to mechanically characterize the mixtures produced, whereas porosity and constant head permeability tests were also carried out to assess the material hydraulic properties.Firstly, the experimental results were compared with the requirements established in international guidelines (ACI 522R-10, NBR 16416(2015) and VTT-R-080225-13). The results complied with the guidelines indicating it is feasible to produce pervious concretes with the sustainable aggregates used in the study in low structural applications such as walkways. On the other hand, a correlation between permeability and porosity was proposed based on Darcy’s and Bernoulli’s laws. The proposed equation, obtained by means of a non-linear regression, is an exponential equation that characterizes the hydraulic efficiency of the internal channels of the material considering the pores interconnection. The correlation between porosity and permeability was finally validated using results from the literature showing the same trend found in laboratory, and therefore it was demonstrated that the proposed correlation in an efficient tool to predict the hydraulic efficiency of pervious concrete.

“…The constant head permeability test follows the principle of Darcy's Law [13,[25][26][27] and basically measures the amount of water passing through the specimen over a given time interval. For this test, the specimens used in the compressive strength test were again used, also in the saturated surface dry condition.…”

ResumoThe objective of this work is to make feasible the use of FEA slag instead of the conventional bulk aggregate in the pervious concrete (PC) production, reaching the minimum parameters required by NBR16416/2015 and ACI 522R-10. This substitution would minimize the use of natural aggregates, besides taking advantage of a residue that has no specifi c destination. In order to reach the objective, three FEAs with diff erent grain sizes were chosen: 6-10 mm (A), 10-20 mm (B) and fi nally a mixture of the two previous ones (C) in the proportion 30-70 respectively. In order to evaluate its mechanical behavior, tests of compressive strength and fl exural tensile tests were carried out, while the evaluation of the hydraulic behavior, porosity and constant head permeability test were performed. The compressive strength varies from 19-31MPa and 3-4MPa for fl exural tensile strength was obtained. In hydraulic terms, the porosity varied from 15-20% and the permeability coeffi cient was 10-12mm/s. There is also a direct infl uence of grains of size less than 4.8 mm (small aggregate) on the compressive strength and permeability of PCs. At the end of the results, it was possible to establish a correlation between the compressive strength, the permeability and the percentage of grains inferior to 4.8mm (sand%), being this positive in relation to the studied variables, that is, the mechanical and hydraulics. Therefore, it has been concluded that the total substitution of conventional aggregates by FEA in CoPe manufacturing will comply with the minimum parameters of NBR 16416/2015.O objetivo deste trabalho é viabilizar o uso de escória de forno elétrico (FEA) em substituição ao agregado graúdo convencional na fabricação de concreto permeável (CoPe), atingindo os parâmetros mínimos exigidos pela norma NBR16416/2015. Esta substituição minimizaria a utilização de agregados naturais, além de aproveitar um resíduo que não tem destinação específi ca. Para alcançar o objetivo foram escolhidos três FEA's com diferentes distribuições granulométricas: 6-10 mm (A), 10-20 mm (B) e fi nalmente uma mistura das duas anteriores (C) na proporção 30-70 respectivamente. Para avaliar seu comportamento mecânico foram realizados ensaios de resistência à compressão e tração na fl exão, enquanto na avaliação do comportamento hidráulico, índice de vazios e permeabilidade à carga constante foram realizados. Na compressão foram obtidas resistências variando de 19-31MPa e 3-4MPa na tração na fl exão. Em termos hidráulicos, o índice de vazios variou de 15%-20% e o coefi ciente de permeabilidade de 10-12mm/s. Também se verifi ca a infl uência direta dos grãos de tamanho inferior a 4.8 mm (agregado miúdo) na resistência à compressão e na permeabilidade dos CoPes. Ao fi nal, a partir dos resultados obtidos foi possível estabelecer uma correlação entre a resistência à compressão, a permeabilidade e a porcentagem de grãos inferiores a 4.8mm (%areia), sendo esta positiva em relação às variáveis estudadas, ou seja, as propriedades mecânicas e hidráulica.

It is important to evaluate the effectiveness of permeable pavements on flood mitigation at different spatial scales for their effective application, for example, sponge city construction in China. This study evaluated the effectiveness of three types of permeable pavements (i.e., permeable asphalts (PA), permeable concretes (PC), and permeable interlocking concrete pavers (PICP)) on flood mitigation at a community scale in China using a hydrological model. In addition, the effects of clogging and initial water content in permeable pavements on flood mitigation performance were assessed. The results indicated that in 12 scenarios, permeable pavements reduced total surface runoff by 1-40% and peak flow by 7-43%, respectively. The hydrological performance of permeable pavements was limited by clogging and initial water content. Clogging resulted in the effectiveness on total surface runoff reduction and peak flow reduction being decreased by 62-92% and 37-65%, respectively. By increasing initial water content at the beginning of the simulation, the effectiveness of total runoff reduction and peak flow reduction decreased by 57-85% and 37-67%, respectively. Overall, among the three types of permeable pavements, PC without clogging had the best performance in terms of flood mitigation, and PICP was the least prone to being clogged. Our findings demonstrate that both the type and the maintenance of permeable pavements have significant effects on their performance in the flood mitigation. national scale, with the innovation of finding ecologically suitable alternatives to mitigate the impacts of water-related problems resulting from "too much water" or floods, "too little water" or water scarcity, and "too dirty water" or water pollution [8,9]. One of the core objectives of the construction of sponge cities is to control and mitigate the increasing challenges of urban flooding/waterlogging [10]. The Central Government of China has provided financial support to implement the sponge city plan in 30 pilot cities around China [9][10][11]. However, the sponge city concept is still a relatively new idea and it requires more research on urban hydrologic theory and different engineering approaches in many cities in China.Permeable pavement is one such technology in sponge city construction that is highly recommended by the Chinese Ministry of Housing and Urban Rural Development (MHURD) [12]. This technology has been studied and implemented in many areas in the world to manage urban stormwater under different plans with terminologies such as sustainable urban drainage systems, low impact development, best management practices, and others [13][14][15]. Reductions in storm runoff peak, runoff volume and improvement in water quality by permeable pavement systems have been widely reported [16][17][18][19]. For example, Pyke et al. [16] reported that stormwater runoff was more sensitive to changes in impervious covers than changes in precipitation volume and intensity. Damodaram et al. [19] demonstrated that permeable pavements had...
