Definitions

• the present invention refers to a method to increase t adherence between a relatively glassy surface, e.g. a ste surface and a substance, e.g. mortar, concrete, grout, plast or the like, which can be applied on or around said surfa and which pourable and which solidifies to a rigid form.
• a relatively glassy surface e.g. a ste surface
• a substance e.g. mortar, concrete, grout, plast or the like
• a form face is coated by a plastic material, for example a gelcoat, whereby short fibres or flocks are spraye on to the plastic material, whereby the fibres are raised b electrostatic charging.
• a plastic material for example a gelcoat
• short fibres or flocks are spraye on to the plastic material, whereby the fibres are raised b electrostatic charging.
• the gelcoat has cured concrete i cast against it.
• the gelcoat forms an integrated layer wit the concrete and when this has cured the form face will b removed.
• the form face do not constitute an part of the completed product.
• 'BU consists of a pan of galvanized sheet of steel, in which th concrete mass is cast.
• the pan thereby constitutes the tensil reinforcement of the concrete slab.
• the sheet of steel can act as a rein orcement, i spite that one has tried to give the sheet such a roug surface as possible, or has provided it with corrugations disintegrations or elevations of other kinds.
• tongues of hobbings and punching of tongues, which are folde against the concrete mass has not been enough to give th necessary adherence to make it possible to contemplate th sheet as an integrated unit together with the concrete sla and which is able to carry occuring extension strains.
• the object with the present invention is to provide a metho to increase said adherence in a simple and a relatively chea way without that the glossy surface being exposed t deformations or weakenings, and which adherence should b accomplished on even surfaces as well as on single or doubl curved surfaces and also in recesses which- are difficult t access.
• the green concrete mass is suck into the fibre flock layer and into every single fibre means of the capillarity and a very unexpected stro adherence is thereby obtained, which results in that it h been possible to produce very thin concrete beams, with thickness of only about 25 mm, and these beams are handl during the manufacturing, the transportation and the mounti without that the slab show any tendency to crack.
• a further object, where the increased adherence will useful, is as an underlayer at grouting of e.g. ste constructions and to increase its fire resistance, whereby th grout or mortar mass may be applied by spraying (e.g guniting).
• the method according to the invention may also b used at manufacturing of phasade or mounting base elements, a manufacturing of floor structures and so on.
