The feasibility of transforming the residues cultivation two rocks into secondary raw materials through alkali activation process has been assessed. Mixtures a sulfate-bearing kaolinitic clay (L02-K) and sludge derived by sewing Pietra Serena stone (sPS) have investigated. These were preliminarily treated at high temperature to improve their reactivity (heat-treated samples are hereafter labell...

This study investigates the removal of tungsten from simulated water using biopolymer coated particles (i.e. chitosan coated clay) and natural clay. The effects of initial tungsten concentration (from 20 to 500 ppm) and water pH (4, 5.5 and 6.4) on zeta potential and tungsten removal were studied for both chitosan coated clay and natural clay. It was found that the net surface charge of natural...

Chimpanzees of the Sonso community, Budongo Forest, Uganda were observed eating clay and drinking clay-water from waterholes. We show that clay, clay-rich water, and clay obtained with leaf sponges, provide a range of minerals in different concentrations. The presence of aluminium in the clay consumed indicates that it takes the form of kaolinite. We discuss the contribution of clay geophagy to...

Deoxyribonucleic Acid (DNA) has been recently found to be an efficient renewable and environmentally-friendly flame retardant. In this work, for the first time, we have used waste DNA from fishing industry to modify clay structure in order to increase the clay interactions with epoxy resin and take benefit of its additional thermal property effect on thermo-physical properties of epoxy-clay nan...

Hybrids based on recycled high density polyethylene (RHDPE) and organic clay were made by melt compounding. The influence of blending method, compatibilizers, and clay content on clay intercalation and exfoliation, RHDPE crystallization behavior, and the mechanical properties of RHDPE/clay hybrids were investigated. Both maleated polyethylene (MAPE) and titanate could improve the compatibilizat...

A controlled greenhouse experiment was conducted to study the fraction, uptake and fixation of phosphorus (P) and potassium (K) in three soils with contrasting characteristics. The experiment was carried out in two phases, viz., sorghum-Sudangrass depletion and test crop experiment with maize with three levels of fertility status (depleted, original and fertilized with 40 mg kg-1 P and K) and t...

The present study aims to develop an innovative scientific methodology for adjusting the physicochemical composition of any clay soil make it appropriate construction applications. realized research was carried out on unexploited clayey extracted from Bensmim village (Morocco). Another sample "Extrabrick" brick manufactory also used as a reference since is produce high-quality bricks. Raw mater...

The article investigates the possibilities of obtaining high–quality expanded clay based on Gurlen deposit Republic Uzbekistan, with additives from local oil and fat combines – gossypol pitch dune sand Tuprakkala massif. It is determined that addition to raw mixture within specified limits significantly increases swelling mass. was also mass (together pitch) in moderate quantities contributes a...
