“…It should be pointed out that within this research, only one clogging event was undertaken, but with a significantly higher clogging agent concentration than it should appear in a pavement service life. For a holistic approach to pervious concrete pavement behavioural assessment in clogging conditions, repetitive clogging events could be tested with different clogging agent types and with a simulation of some kind of a maintenance program as presented in different literature [21,22,[26][27][28].…”

“…One of the main disadvantages of pervious concrete pavement is also its maintenance, which is oriented mainly to clogging prevention that can lead to permeability reduction. Numerous research works within the last few years [21][22][23][24] emphasize the importance of the clogging phenomenon on pervious concrete pavement performance. Clogging is caused by the interlocking of the pores with clogging particles and pore size definition can be useful in determining clogging potential [25], which is also related to the tortuosity of the connected porosity [26].…”

This paper aims to assess the influence of clogging on paving material (pervious concrete) drainage characteristics as well as the influence of the properties of an unbound base layer on drainage characteristics of the whole paving system. The clogging influence has been studied measuring the drainage characteristics on pervious concrete flags before and after their clogging, according to ASTM C1701-09. Additionally, the drainage characteristics of uncontaminated pervious concrete as a paving material was assessed using the falling head method. To assess the influence of properties of an unbound base course (UBC) on drainage characteristics of the whole paving system, the unbound base layer was compacted in two different levels of compaction and the drainage characteristics were measured (according to ASTM C1701-09). It is concluded that pervious concrete prepared with a smaller aggregate fraction is more prone to clogging. Regarding the influence of UBC, it is important to find a balance between pervious concrete infiltration and UBC exfiltration rate, particularly in a case of pervious concrete flags made of coarse aggregate.

“…Dentre os pontos discutidos anteriormente para que o concreto permeável cumpra sua função drenante e removedora de partículas deve-se ter atenção a periodicidade de limpeza para desobstrução dos poros, neste aspecto Sandoval et al (2020) explica que por possui uma ampla área exposta, no concreto permeável o intemperismo naturalmente provoca seu entupimento, prejudicando a capacidade de infiltração da água no solo e a capacidade hidráulica de armazenamento do material, destacando ainda a limpeza com água e o ar como formas de desobstrução de acordo com a natureza do sedimento.…”

Nos grandes centros urbanos, a constante impermeabilização das vias intensifica alagamentos e enchentes, gerando inúmeros transtornos à população. O uso do concreto permeável como mecanismo de drenagem de águas pluviais e residuárias tem sido uma solução parcial para esse tipo de problema de drenagem, inclusive com a adição em sua composição de materiais com propriedades adsorventes que visem a melhoria de parâmetros físico-químicos e biológicos da água. Portanto, este artigo tem como objetivo geral trazer importantes resultados de diversos estudos utilizando concreto permeável com adições minerais e mostrar os benefícios nas propriedades mecânicas e adsorventes desse tipo de concreto, com ênfase na utilização do biocarvão. Para isso, optou-se como metodologia, fazer uma breve revisão da literatura, no qual foram analisadas pesquisas concluídas disponíveis em base de dados online como Scopus, Science Direct a partir do ano de 2015 utilizando como descritores em inglês: “Concrete” AND “Biochar”, “Concrete porous” AND “Biochar”, “Pervious concrete” AND “Biochar”, “Treatment of water” AND “Concrete porous”, “Cementitious materials” AND “Biochar”. Foram selecionadas 51 referências sendo assim especificados: 48 artigos científicos, 1 norma e 2 capítulos de livros. Constatou-se que a adição de minerais adsorventes e biocarvão no concreto podem promover melhoria de parâmetros de qualidade da água como diminuição de turbidez, nitrogênio totais (NT), Fósforo Totais (PT), DQO, DBO, entre outros, e promoverem, em alguns casos, ganho de resistência mecânica dos concretos produzidos.

“…Shang and Sun [70] developed a Green pervious concrete by introducing organoclay to the conventional pervious concrete as a remediation function for PAH removal. PC with a small addition of organoclay could substantially remove PAHs contaminants and it also has much stronger adsorption and retardation capacity than the conventional pervious concrete [66] . PC has a great potential to be used as a pavement material with the stormwater purification function.…”

Pervious concrete a sustainable solution with limited fines or no fines and interconnected voids, has many environmental benefits, such as reducing the stormwater run-off, improving the groundwater table, reducing water pollution, and mitigating urban heat island. Many research works have been done in Pervious Concrete (PC) by varying different parameters such as, types of aggregate, aggregate gradation, water-to-cement (w/c) ratio, cement-to-aggregate ratio, geopolymer binder, ultra-high strength Matrix and compaction techniques. All these parameters have direct influences on the strength, porosity, permeability, hydraulic efficiency and durability characteristics of PC. The main aim of this paper is to review the recent work carried out in pervious concrete under six different categories (i) Effect of binders, coarse aggregate, admixtures and fibers used in PC (ii) Mechanical and durability properties (iii) pore structure characteristics (iv) Study on Clogging Effect (v) Role of PC in the water purification process and (vi) Numerical model in PC.
