“…The permeability coefficient for mixes P 1-4 and V 1-4 was determined by testing cylinder-shaped specimens described in 2.4 using the constant head permeability test presented in [6]. The method is convenient for materials with the permeability coefficient of k >10 -4 cm/s and based on Darcy's law.…”

“…Due to such composition, pervious concrete made without additives has a relatively low compressive strength varying from 2.8 to 28 MPa [2,3,4]. To avoid filling of voids with cement paste, its quantity is regulated by prescribing a lower water to binder ratio, usually between 0.26 and 0.5 [5,6,7]. Due to its relatively low strength and high permeability, pervious concrete is suitable for the construction of less trafficked pavement structures, footpaths and parking areas, namely in regions with frequent downfalls.…”

Effect of aggregate grading on pervious concrete propertiesFresh and hardened pervious concrete properties are experimentally determined in the paper. The correlation between the compressive strength, flexural tensile strength, flow coefficient, and aggregate grading is analysed. As there is no approved method for determining the flow of water through pervious concrete, the testing was conducted in accordance with the already known methods, but using own apparatus. Optimum strength and flow capacity results were obtained on gap graded samples with the 0-2 mm sand content of less than 15 %. Utjecaj granulometrijskog sastava na svojstva procjednog betona U radu su eksperimentalno određena svojstva svježeg i očvrsnulog procjednog betona. Analizirana je zavisnost tlačne čvrstoće, vlačne čvrstoće savijanjem te koeficijenta protočnosti o granulometrijskom sastavu agregata. Budući da ne postoji propisani način određivanja protjecanja vode kroz procjedni beton, ispitivanje je provedeno sukladno poznatim metodama, ali s pomoću samostalno izrađenih pomagala. Na uzorcima s diskontinuiranom granulometrijskom krivuljom, gdje udio frakcije pijeska 0-2 mm u sastavu mješavina nije prelazio 15 %, dobiveni su optimalni rezultati čvrstoće i protočnosti. Einfluss der Kornzusammensetzung auf die Eigenschaften durchlässigen BetonsIn dieser Arbeit sind Eigenschaften frischen und gehärteten durchlässigen Betons durch experimentelle Versuche ermittelt worden. Der Zusammenhang zwischen Druckfestigkeit, Biegezugfestigkeit, Durchflusskoeffizient und Gesteinskörnung ist analysiert worden. Da kein bestimmtes Verfahren zur Ermittlung des Wasserflusses durch durchlässigen Beton vorgeschrieben ist, sind in den Versuchen bekannte Vorgehensweisen mittels der eigenen Ausrüstung angewandt worden. Optimale Resultate in Bezug auf Festigkeit und Durchlässigkeit sind an Proben mit diskontinuierlichen Sieblinen erzielt worden, die einen 0-2 mm Sandkorngehalt unter 15 % nachweisen. Schlüsselwörter:durchlässiger Beton, Festigkeit, Gesteinskörnung, Durchflusskoeffizient

“…Coal bottom ash (BA) is generated by the combustion of pulverized coal, and many features of BA largely satisfy the aforementioned conditions to fabricate a porous concrete (Singh and Siddique 2014;Kim et al 2014a). In particular, the highly porous structure and the rough surface property of BA is suitable for forming sufficient voids in the matrix of porous concrete (Kuo et al 2013;Kim et al 2014b). However, BA contains and may leach a variety of heavy metals such as cadmium, copper, and lead, inhibiting a broad range of applications in a construction industry (Jang et al 2015a).…”

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.
