“…Among the various clay modifications, anchoring of carbonaceous materials, which are abundant in oxygen-containing groups and exist on the surface of solid adsorbents such as clay minerals, has emerged as a new class of adsorbent for contaminant removal (Anadão et al, 2011(Anadão et al, , 2014Chen et al, 2011;Kumar et al, 2011;Ai and Li, 2013). Clay minerals or zeolite can act as a uniform dispersion medium for nano-sized carbon particles and thus ideally help improve the composite's reactivity to target pollutant compounds (Katsuki et al, 2005;Anadão et al, 2011;Wu et al, 2014).…”

“…The adsorption capacity of AC/clay was studied in terms of vapor pressure of the gas to adsorb and the pore size distribution of the resulting composites. Using toluene as a contaminant, it was confirmed that the adsorption capacity of AC/clay composites offers a sufficiently large and easily accessible external surface area [155,156]. The initial adsorption takes place at slower diffusion into the narrow microspores of AC/clay composites, where the contaminant is more strongly adsorbed.…”

This paper provides a concise review of recent advances in activated carbon (AC) and its corresponding modified material. Topics covered in this work include the synthesis and characterization of AC as the feedstock materials, as well as the properties and applications of the subsequent hybrid material for different industries. Numerous research studies have since reported remarkable physical, chemical, thermal, conductivity, porosity, and mechanical (stiffness and strength) properties of AC in different types of multiple material matrices, including polymers, metals, and ceramics. The incorporation of AC particles into material matrices may result in the formation of an entire new class of advanced materials, due to the resulting strong interfacial bonds of the hybrid components. Although this requirement is no different from those that offer conventional hybrid materials, the scale of the reinforcement and filled phase of the AC has changed from micrometers to nanometers. This create opportunities to increase the potential applications of AC hybrid materials of the development of fundamentally unique new materials for in chemical conversion, environmental, and fuel storage applications.

“…The main component of bentonite is montmorillonite, which is a clayey mineral belonging to the class of phyllosilicates called smectites. The special properties found in bentonite clays, especially their adsorption and binding capacities, make them particularly suitable for use in sectors such as the ceramic industry, the food industry, the foundry and smelting sector, water treatment [29] and, indeed, many others. In the case under examination, the bentonite clay is a waste from the bleaching oil process and a consecutive anaerobic digestion for the biogas production.…”

There has been a significant increase in the demand for using recycled materials in construction because of the lack and limitation of available natural resources. A number of industrial and domestic waste products are being used in the replacement of traditional materials for road construction, and many studies have been carried out in recent years on the use of different recycled materials in substitution of conventional fillers in Asphalt Concretes (AC). The aim of this laboratory research is to analyze the physical characteristics of three different recycled fillers and compare them with those of a traditional limestone filler. The alternative fillers presented in this paper are: a waste bleaching clay that comes from two consecutive stages in the industrial process for decolouring vegetable oils and producing biogas (Ud filler), a dried mud waste from a tungsten mine (MW filler) and a recycled glass powder (Gl filler). Results show significant differences between the fillers, and, in particular, Rigden Voids (RV) seem to have the largest potential influence on the rheology of ACs.
