This work reports the behavior of montmorillonite magnetite mixtures of varying composition in aqueous dispersions and evaluates their adsorbing properties using a cationic organicpollutant, methylene blue (MB+), and an ...

Gas aggregation is a well known method used to produce clusters of different materials with good size control, reduced dispersion, and precise stoichiometry. The cost of these systems is relatively high and they are generally ...

In this Chapter, a thermodynamically consistent gradient model is proposedfor natural aggregate concrete and then, modified to take into account theaddition of different contents of recycled aggregates and its influence ...

Geometric mean diameter (GMD), erodible fraction (EF), and dry aggregate stability (DASt) are soil parameters deduced by dry sieving that are used to identify soil susceptibility to wind erosion. Values of GMD, EF, and ...

Indian Black Earths (IBEs) are distributed throughout the Amazon. They are characterized by their high chemical fertility and agricultural potential. IBEs have high organic carbon, favouring the improvement of soil structure. ...

At present, reducing the environmental impact of the construction industry is a major subject of study. In terms of the use of recycled concrete aggregates (RCA), most recently conducted studies have shown that the use of ...

Biomolecules labeled with superparamagnetic nanoparticles can be selectively removed from complex reaction mixtures using an external magnetic field. Amino-functionalized superparamagnetic iron oxide nanoparticles (amino-SPION) ...

Research has been developing ways to mitigate water absorption effects from recycled concrete aggregates use in new concrete mixtures, so that the mechanical and durability characteristics of these aggregates and the ...
