Abstract (en)
[origin: WO2020229623A1] The invention relates to the use of a particulate material comprising a particle-shaped synthetic amorphic silicon dioxide having a particle size distribution with a median ranging from 0.1 to 0.4 µm, determined using laser diffraction, in the form of an individual component or one of a plurality of components as an additive for a molding material mixture, comprising at least: a refractory molding base material with an AFS grain fineness number ranging from 30 to 100, particulate amorphic silicon dioxide having a particle size distribution with a median ranging from 0.7 to 1.5 µm, determined using laser diffraction, and water glass in order to increase the moisture resistance of a molded body which can be produced by heat curing the molding body mixture. The invention also relates to corresponding methods, mixtures, and kits.
