Abstract A polymer-enhanced bentonite-sand mixture has been widely used as a clay liner. This research focuses on the potential use of chitosan natural polymer mixed with bentonite liner base material. The is type calcium bentonite, which easily obtained in market. Meanwhile, produced from shrimp shell waste and also available process mixing percentage 2–6% was carried out using certain method,...

Photocatalyst nanocomposites of ZnO/bentonite clay are synthesized by Solid-state ion exchange method. Ion exchange intercalation process of clays is used to incorporate the catalyst into the basal space of the layered structure of clays. The purpose of this study is to find a new method, which is focused on simplifying and saving time to prepare ZnO-bentonite composite with photocatalyst prope...

Plastic concrete consists of aggregates, cement, water and bentonite, mixed at a high water cement ratio, to produce a ductile material. It is used for creating an impermeable barrier (cut-off wall) for containment of contaminated sites or seepage control in highly permeable dam foundations. The effects of water to binder ratio and clay dosage on mechanical properties of plastic concrete were i...

The present study reports, the synthesis of ZnO-bentonite nanocomposite by the incorporation of ZnO with bentonite clay. The nanocomposite was characterised by XRD and SEM. ZnO-bentonite was effectively used for removal of Methylene Blue (MB). Removal of MB takes place by photocatalytic degradation and adsorption. Photocatalytic degradation of MB occurs by advanced oxidation process. The factor...

Presence of heavy metal ions in wastewater is an important public concern. Adsorption are commonly used technique to remove various pollutants, including the ions, from contaminated water sources. However, common methods for adsorption are not completely efficient at low ion concentrations and the adsorbent should be improved in order to reaching the acceptable levels of adsorption efficiency. ...

Carbon dots and their derivatives with fascinating photoluminescent properties have recently attracted tremendous scientific attention. This work describes the preparation of novel fluorescent bentonite clay (B), modified carbon dots...

Abstract This study deals with improving the properties of lightweight aggregate by addition Ca-bentonite mineral to expandable clays. The bentonite can result in advanced materials which meet international standards. Besides material, twelve different clays (from Egyptian and Hungarian mines) were studied X-ray fluorescence (XRF), powder diffraction (XRD, Rietveld method), a heating microscope...
