“…Given the nuisance of the spoil, attempts have been made to incorporate marble waste into many construction materials, which include modifying cement mortar properties (Hwang et al 2008;Corinaldesi et al 2010), application as a recycled aggregate in concrete production (Binici et al 2008;Gencel et al 2012;Topcu et al 2009;Ergun 2011;Hebhoub et al 2011;Belaidi et al 2012;Bacarji et al 2013;Andre et al 2014), as an aggregate in asphaltic concrete (Akbulut, Cahit 2007;Karasahin, Terzi 2007), as a raw material in brick production (Bilgin et al 2012;Eliche-Quesada et al 2012) and as raw material in cement production (Aruntas et al 2010;Aliabdo et al 2014).…”

Abstract. Trinitrotoluene (TNT), a commonly used explosive for military and industrial applications, can cause serious environmental pollution. 28-day laboratory pot experiment was carried out applying bioaugmentation using laboratory selected bacterial strains as inoculum, biostimulation with molasses and cabbage leaf extract, and phytoremediation using rye and blue fenugreek to study the effect of these treatments on TNT removal and changes in soil microbial community responsible for contaminant degradation. Chemical analyses revealed significant decreases in TNT concentrations, including reduction of some of the TNT to its amino derivates during the 28-day tests. The combination of bioaugmentation-biostimulation approach coupled with rye cultivation had the most profound effect on TNT degradation. Although plants enhanced the total microbial community abundance, blue fenugreek cultivation did not significantly affect the TNT degradation rate. The results from molecular analyses suggested the survival and elevation of the introduced bacterial strains throughout the experiment. Keywords: TNT, bioaugmentation, biostimulation, phytoremediation, microbial community.

“…Most studies report a greater absorption of water in the Study of potential advantages of pre-soaking on the properties of pre-cast concrete made with recycled coarse aggregate • 9 case of concrete made with RCA as a result of the incorporation of a more porous material such as cement paste adhering to the aggregate (33,54,55). However, studies such as that of Gencel et al (30) report reductions of 62%, similar to those obtained in this study, with a similar coarse fraction replacement in the manufacture of concrete paving blocks.…”

“…Studies such as that of Etxeberria et al (14) and Kou (25) focus on the properties of recycled concrete (RC) for use as structural concrete, and report satisfactory results provided that less than 25% of the coarse fraction is replaced. Other studies have demonstrated the feasibility of using RA in the production of nonstructural concrete (13,15,26) such as concrete blocks for use in partition walls (11,27), paving blocks (8)(9)(10)(28)(29)(30), paving flags (8, 31) and concrete kerbs and floor blocks (10). These studies have shown that the quality of the pre-cast elements depends on the extent to which NA is replaced by RA, with values that ranged from 25-50% for paving blocks, 30-65% in the case of paving flags, 50% for kerbs and partition wall concrete blocks, or even 100% in the manufacture of floor blocks.…”

Recycled aggregate (RA) from construction and demolition waste is traditionally used for the manufacture of concrete for different applications. Due primarily to high water content required by RA, the quality of the concrete is determined by the amount of replacement RA. The aim of this study is to determine if RA pre-soaking enhances the properties of pre-cast concrete for street furniture, with low mechanical and structural requirements, in which 100% of the coarse fraction is replaced. The results of physical and mechanical tests performed on concrete specimens in which the RA was pre-soaked using five different methods applied are compared with a reference concrete sample and a concrete sample made with non-pre-soaked RA. The results show that non-pre-soaked RA offers improved physical-mechanical properties for pre-cast concrete, except for the workability; problems arising from poorer workability could be improved with the use of plasticizers, which can be easily included in the production process. RESUMEN: Estudio de las ventajas potenciales del premojado en las propiedades del hormigón prefabricado con árido reciclado grueso.El árido reciclado (AR) procedente de residuos de construcción y demolición se utiliza tradicionalmente en la elaboración de hormigón para diferentes aplicaciones. Debido principalmente al mayor contenido en agua requerido por el AR, la calidad del hormigón está determinada por la cantidad de AR reemplazado. El objetivo de este estudio es determinar si el AR premojado mejora las propiedades del hormigón prefabricado para mobiliario urbano, con bajas exigencias mecánicas y estructurales, en el que se sustituye el 100% de la fracción gruesa. Los resultados de los ensayos físicos y mecánicos realizados sobre muestras de hormigón en las cuales el AR se ha premojado usando cinco métodos diferentes se han comparado con una muestra de hormigón de referencia y una muestra de hormigón fabricada con AR no premojado. Los resultados muestran que el AR no premojado proporciona propiedades físico-mecánicas mejoradas en el hormigón prefabricado, a excepción de la trabajabilidad; los problemas derivados de una deficiente trabajabilidad pueden ser fácilmente corregidos con la incorporación de plastificantes en el proceso de fabricación.

“…Latterly, incorporation of sewage sludge was itemized to create good performance blocks and has replaced sand up to 10% with sewage sludge [6]. Several wastes are reused as a substitute of fine aggregates with cement for making concrete blocks which mostly includes CRT funnel glass, marble waste and ferrochromium slag [7][8][9].…”

Water treatment plants (WTP) produce copious quantities of solid waste in the form of sludge that is deteriorating water resources, agriculture lands and human health. It should be discarded properly but a grave issue is finding ecological solution for its ultimate disposal. This study will provide an idea of incorporating sludge into soil-cement bricks that are used for construction providing dual benefits: reducing amounts of sludge and introducing cheaper bricks. A sample of sludge was analyzed for chemical constituents, plasticity value, particle size and content of organic matter. Sludge bricks incorporating 10 % of waste material by weight were prepared. The quality of sludge bricks was evaluated in terms of mechanical and physical properties (compressive strength test, water absorption test and apparent density test). The obtained results have revealed that waste material is mostly composed of plastic and could be utilized for manufacturing of sludge bricks. The compressive strength and density of bricks reduced with increasing amounts of sludge. However, the compressive strength of the bricks could even meet the standard requirement.
