The problem often arises of installing machines that must operate with high precision, such as drilling machines, milling machines and lathes, in such a way that they are damped and therefore ensure that resonant vibrations are as little as possible and are not propagated. . Machine foundations made of cast steel, granite or polymer concrete are known. Cast steel foundations are not useful in all cases as they can emit resonant vibrations, polymer concrete is not thermally stable enough in all cases, although granite meets the necessary requirements better,
Foundations from natural rock are very expensive as they have to be crushed and processed.

ことができる。 The base (1; in the attached drawing) containing the inorganic material according to the invention can be manufactured in all desired dimensions by molding. Due to its high specific gravity and structure, this foundation has only a slight tendency to resonance and makes it possible, among other things, for damping arrangements in high-speed precision machines. The surface can be later processed for mechanical installation (2; in the accompanying drawing). This foundation has a high compressive strength of at least 60 N/mm 2 and a sufficient hardness of about 6 to 7 on the Mohs scale. An aqueous potassium silicate solution containing potassium hydroxide forms a curing agent, which reacts with the oxide mixture or with the hydrous silicic acid or metakaolin. The potassium silicate solution may be a commercially available potassium silicate solution, a so-called water glass solution or, according to the invention, a hydrous amorphous dispersible powdered silicic acid may be dissolved in a solution of potassium hydroxide or a hydrous solution may be used to liquefy solid potassium hydroxide. It can be produced by stirring and mixing into amorphous silicic acid.

重量％がSiO2として測定される。 Oxide mixtures containing amorphous SiO 2 and aluminum oxide contain highly variable amounts of both oxides, the total proportion of which is often more than 75-90% by weight of the oxide mixture, but not other oxides. The content may be lower or higher than 75% by weight. The oxide mixture is anhydrous. It consists solely or mainly of a mixture of oxides. Such oxide mixtures are typically produced as powders in industrial high-temperature melt processes and initially form a vapor or gas phase from which they are separated as fine powders on cooling. Frequently, the oxide mixture does not correspond to the composition of the industrial melt product. In the radiograph, there is no crystalline SiO2 , but
