Beschreibung
Zusammenfassung:	It is provided a method of cementing comprising a) providing a cement slurry by mixing: i) a cement composition comprising an cement and an amount of magnetic nanoparticles from 0.01 wt. % to 10 wt. % relative to the amount of cement (0.01% to 10% BWOC), wherein the magnetic nanoparticles have a mean particle size determined by Transmission Electron Microscopy (TEM) from 10 nm to 50 nm and a crystallite size determined by the Scherrer equation which is at least an 80% the mean particle size; and ii) water; and b) applying to the cement slurry an alternating magnetic field of from 25 mT to 60 mT at a frequency from 50 kHz to 200 kHz) in order to set the cement slurry. It is also provided the mentioned cementing composition and an article of manufacture obtainable by the method of cementing.
