“…A porous structure is the key feature of PC, and porosity is the most important factor influencing mechanical strength, permeability, and durability. In general, the porosity of PC mixtures is 15-30% and the corresponding permeability coefficient lies in the range of 1-15 mm/s [17,18]. Higher porosity produces higher permeability, but is disadvantageous to mechanical strength and durability.…”

Pervious concrete (PC), as an environmental friendly material, can be very important in solving urban problems and mitigating the impact of climate change; i.e., flooding, urban heat island phenomena, and groundwater decline. The objective of this research is to evaluate the strength, permeability, and freeze-thaw durability of PC with different aggregate sizes, porosities, and water-binder ratios. The orthogonal experiment method is employed in the study and nine experiments are conducted. The compressive strength, flexural strength, permeability coefficient, porosity, density, and freeze-thaw durability of PC mixtures are tested. Range analysis and variance analysis are carried out to analyze the collected data and estimate the influence of aggregate size, porosity, and water-binder ratio on PC properties. The results indicate that porosity is the most important factor determining the properties of PC. High porosity results in better permeability, but negatively affects the mechanical strength and freeze-thaw durability. PC of 15% porosity can obtain high compressive strength in excess of 20 MPa and favorable freeze-thaw durability of 80 cycles without sacrificing excessive permeability. Aggregate size also has a significant effect on freeze-thaw durability and mechanical strength. Small aggregate size is advantageous for PC properties. PC with 4.75-9.5 mm coarse aggregate presents excellent freeze-thaw durability. The influence of the water-binder ratio on PC properties is not as significant as that of aggregate size and porosity. An optimal mix ratio is required to trade-off between permeability, mechanical strength, and freeze-thaw durability.functionally and environmentally friendly material [9]. It allows rainwater to permeate into the ground and replenish groundwater, which effectively alleviates the rapid decline of groundwater. In addition, PC pavement can solve other urban environmental problems [10][11][12]. With the development of Chinese sponge city construction, PC will be widely applied in road structure [13]. Therefore, PC is of great significance for mitigating climate change, solving urban problems, and promoting the development of human society [14][15][16].The main properties of PC are strength, permeability, and durability. A porous structure is the key feature of PC, and porosity is the most important factor influencing mechanical strength, permeability, and durability. In general, the porosity of PC mixtures is 15-30% and the corresponding permeability coefficient lies in the range of 1-15 mm/s [17,18]. Higher porosity produces higher permeability, but is disadvantageous to mechanical strength and durability. Due to the absence of fine aggregate and the existence of high porosity, the strength of PC is lower than that of traditional impervious concrete. The compressive strength of PC is 5-30 MPa and tensile strength is 1. 20]. In addition, the freeze-thaw durability of PC is a very important property, especially for PC used in seasonally frozen regions. However, the freeze-thaw durability ...

A summary of 246 studies published in 2016 on topics related to the characterization and management of urban stormwater runoff is presented in the following review. The review is structured along three major topical areas: (1) general characterization of stormwater quantity and quality; (2) engineered systems for stormwater control and treatment, including erosion and sediment control practices, constructed stormwater ponds and wetlands, bioretention, permeable pavement, greenroofs, and rainwater harvesting and (3) watershedscale application of stormwater treatment and control practices. Common research themes and needs highlighted throughout this review include efforts to better understand stormwater transport and treatment mechanisms and their representation in models, advancements to optimize the design of stormwater control measures to meet specific hydrologic and/or water quality targets, and increasing understanding of the biophysical and social factors that influence watershed-scale implementation of low impact development and other stormwater control measures.

“…This concrete has a drainage capacity greater than the conventional one, which reduces the flow of rainwater present in the surface runoff [4]. PC is composed of Portland cement, coarse aggregate and water, with little or no small aggregate (sand), which facilitates the formation of interconnected internal voids that allow the fast and safe flow of water [1,2,5,6]. In terms of mechanical strength, this material works in the range of 3-30 MPa [7][8][9][10], and can be used on pedestrian sidewalks and light traffic pavements.…”

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. Por ta...
