Verfahren zur Abdichtung oder Verfestigung von porösen Formkörpern, Gesteinen oder porösen Formationen unter Verwendung von hyperfeinem Zement
The method for producing a hyperfine cement with a particle size of D 50less than 1 mu m for improving fire protection in polymer materials or components from pressed textiles or natural fibers, comprises grinding cement or cement clinker in a non-aqueous solvent and grinding aids in a ball mill or rotational ball mill, partially separating the non-aqueous solvent and optionally the grinding aids from the obtained hyperfine cement by filtering, centrifugating, decanting or distilling off, and drying the moist hyperfine cement to a free-flowing powder. The method for producing a hyperfine cement with a particle size of D 50less than 1 mu m for improving fire protection in polymer materials or components from pressed textiles or natural fibers, comprises grinding cement or cement clinker in a non-aqueous solvent and grinding aids in a ball mill or rotational ball mill, partially separating the non-aqueous solvent and optionally the grinding aids from the obtained hyperfine cement by filtering, centrifugating, decanting or distilling off, and drying the moist hyperfine cement, which remains after grinding and optionally partially separating the other components, to a free-flowing powder. The obtained cement is mixed in dry form with water to a low-viscous mash. The cement is Portland-cement. Independent claims are included for: hyperfine cement with a particle size of D 50less than 1 mu m; and #a method for sealing or hardening porous molded articles, rocks or porous formations.
