Definitions
- the invention relates to level-compensating fillers according to the preamble of claim 1, a process for their production according to claim 3, a process for their use according to claim 11 and a product containing them according to claim 12.
- Level-compensating fillers for the formation of subfloors in the form of bituperl (bituminized perlite grains), expanded clay concrete, EPS lightweight concrete (EPS is a standardized abbreviation for expandable or expanded polystyrene) and the like are known. These bulk materials should be heat-insulating, load-bearing for the load on floor constructions and should be loadable as soon as possible and also dried out so that the floor built up on top, e.g. Wood / parquets, etc., no moisture damage.
- the invention aims to provide level-compensating fillers which do not have these disadvantages.
- EPS foam particles in particular with a size of up to 20 mm, preferably less than 10 mm and particularly preferably with a size of less than 2 mm, are encased in a plaster shell.
- this sheathing is applied as follows: EPS grains such as styrofoam or the like - which have preferably been heat-treated / sintered beforehand (so that the particle Surface is melted) with a mixture of water and paste, in particular wallpaper paste (for example methylane wallpaper paste) moistened.
- EPS grains such as styrofoam or the like - which have preferably been heat-treated / sintered beforehand (so that the particle Surface is melted) with a mixture of water and paste, in particular wallpaper paste (for example methylane wallpaper paste) moistened.
- paste is to be understood as an adhesive in the form of an aqueous swelling product which, in contrast to glues, forms a highly viscous, non-stringy mass in a low consistency.
- the basic materials are starch, cereal flour and water-soluble cellulose compounds in use.
- the moistening is carried out in such a way that, for example, 100 l of EPS grains are introduced into a compulsory mixer, then, for example, 1/16 l of glue powder (approx. 60 cm 3 ) is dissolved in 8 to 10 l of water, stirred and then poured into the compulsory mixer .
- 10 to 12 liters of building gypsum powder, alpha gypsum powder or alabaster gypsum powder can also be added immediately.
- the gypsum powder particles adhere immediately to the EPS particle surfaces and would harden within a few minutes.
- Another method that can be used according to the invention consists in a mixture of glue water (wallpaper paste, as previously described) and delayed in a mixing trough in which EPS particles are already located
- Add gypsum powder (alpha gypsum) in the form of a "gypsum soup" e.g. 8 1 water in which 0.10 1 glue powder is dissolved, stir with 9 1 gypsum powder.
- the possibly sintered EPS particles are coated with this "gypsum soup”.
- 10 to 15 l of dry gypsum powder - electric gypsum or building plaster - are again added, here too, individual EPS grains are formed, which are coated with gypsum stone.
- individual tuber formation can occur (approx. 5 vol.%) If the mixer shaft runs too slowly.
- these sacks can be filled with EPS particles filled with gypsum stone, e.g. 50 1 or 100 1 bags, again dry gypsum powder are added, e.g. 5 to 20 or 30 vol. %.
- this dry material After emptying the sack contents e.g. on floors this dry material is drawn off at level, then sprayed with cold or warm water mist from above (similar to a steam jet). After only 10 minutes the surface has become so solid that it can be walked on.
- the advantage achieved according to the invention is that the floor structure can be continued immediately, e.g. through the
- a separating layer can be laid beforehand, especially if mastic asphalt is to be applied on top.
- This separating layer consists of corrugated cardboard, which has been made insensitive to moisture. Any moisture content that initially appears as an excess when sprayed with the water spray will disappear in the course of the next few hours, for example with a layer of "gypsolite" fill (“gypsolite” I call the EPS particles, which are coated with the gypsum stone shell) of approx 10 cm because the first moisture penetrates only about 3 cm deep. Afterwards, the residual moisture in the upper moistened layer is successively directed downwards by capillary and solidifies the gypsum dust underneath. A solution has thus been found, in which a further floor construction can take place immediately after pouring the gypsolite layer and subsequent spraying.
