“…Since the development of porous concrete in Japan in the 1980s, it has been applied in various ways to restore groundwater supplies and to reduce the runoff from a site (Sriravindrarajah et al 2012;Bhutta et al 2012). In recent years, industrial by-products such as coal ash and slag have attracted several studies to utilize the materials in the fabrication of eco-friendly porous concretes (Jang et al 2015a;Park and Tia 2004).…”

In the present study, a porous concrete with alkali activated slag (AAS) and coal bottom ash was developed and the effect of carbonation on the physical property, microstructural characteristic, and heavy metal leaching behavior of the porous concrete were investigated. Independent variables, such as the type of the alkali activator and binder, the amount of paste, and CO 2 concentration, were considered. The experimental test results showed that the measured void ratio and compressive strength of the carbonated porous concrete exceeded minimum level stated in ACI 522 for general porous concrete. A new quantitative TG analysis for evaluating CO 2 uptake in AAS was proposed, and the result showed that the CO 2 uptake in AAS paste was approximately twice as high as that in OPC paste. The leached concentrations of heavy metals from carbonated porous concrete were below the relevant environmental criteria.

“…In most studies on carbonation of AAS paste, calcium carbonate was only considered as a carbonated product (Park and Tia 2004;Kim et al 2013;Deja 2002). Eloneva et al reported that AAS paste can be used for CO 2 uptake via the carbonation of calcium components (Eloneva et al 2008).…”

“…Previous research on the removal of inorganic contaminants via pervious surfaces (specifically pervious concrete) shows great potential (Drake et al, 2014;Haselbach et al, 2014;Legret et al, 1996;Luck et al, 2008Luck et al, , 2009Pagotto et al, 2000;Park and Tia, 2004;Pratt et al, 1995). Brattebo and Booth (2003) directly compared water from a permeable pavement system to asphalt runoff and found lower concentrations of motor oil, copper, and zinc with the metals reaching state defined levels of toxicity in 97% asphalt samples, but in only 14% of permeable pavement samples.…”

“…Multiple factors, such as fly ash amendments to pervious concrete and the amount of void space created during the fabrication may influence the removal rates of certain contaminants (Luck et al, 2008(Luck et al, , 2009Park and Tia, 2004). Fly ash, a material commonly added to pervious concrete as a cost-effective replacement for Portland cement, has very rarely been studied for its influence on contaminant removal, despite its high organic carbon content.…”

Pervious concrete is a recognised best management practice. This study investigated the removal efficiencies of various pervious concrete formulations when exposed to total suspended solids, Pb , and total suspended solids, respectively. Removal efficiencies of total suspended solids, Cl -, SO 4 2-, and NO 3 -were not largely influenced by formulation. However, both Pb 2+ and PO 4 3-removal were formulation dependent. Analysis of the void space in each individual pervious concrete cylinder was performed and compared to removal efficiency data. Surprisingly, no significant relationship existed between removal of potential contaminants and void space. Pervious concrete can aid in improving water quality of urban runoff.

“…Compare to conventional concrete, PC has a large volume of air voids. Due to the water-permeating, waterdraining, and water retaining performances of the PC, it has been utilized in road pavements, sidewalks, parks, and infiltration beds for water purification [16] [17]. Fly ash-doped porous concrete (FAPC) is prepared based on conventional PC, which by adding certain proportion of fly ash into PC prepare material, and hope to improve the wastewater treatment effect.…”

Abstract-The aim of this paper was to demonstrate the technical feasibility of AMD treatment using fly ash-doped porous concrete (FAPC). The FAPC were prepared through adding the fly ash into the ordinary porous concretes (PC), and the acid mine drainage (AMD) was treated by FAPC in this paper. The results show that: At influent pH of 2.9-3.4 and 24 h hydraulic retention time, the acidity of AMD was improved significant by FAPC, and which the pH of effluent was maintained at 8-9. The average removal rate of turbidity, COD and TP of AMD were 69.7%, 75.4% and 91.9%, respectively. Compared to none fly ash-doped porous concrete that the FAPC improved the AMD purification effect, for turbidity, COD and TP the average removal rate were increased of 13.6%, 10.0% and 1.9%, respectively. The experimental results also show that, the porosity of all FAPC was decreased after the AMD treated, but all in less than 10% and which does not affect the use of FAPC in AMD treatment. In view of the purification effect of FAPC, it provides a new way of AMD treatment and resources.Index Terms-porous concrete, fly ash, acid mine drainage, pH.
