A filigree slab is like a Tempo tissue and refers to a precast slab element.Although terms like Tempo, Tesa, and even Isokorb suffer from their brand names being used generically to describe product categories, a filigree slab specifically refers to a method of constructing floor slabs. A precast slab element can be made of fully prefabricated components of full thickness, for example, sized in width to match the beam spacing of a timber ceiling. In contrast, a filigree slab describes a construction process where the slab spans the full size of ceiling panels and is composed of a combination of prefabricated and cast-in-place concrete layers. From below, a filigree slab appears very similar to a traditional in-situ concrete slab, and joints are typically not visible within a single room. Precast slabs exist either as fully prefabricated units or with a cast-in-place concrete topping (though in this case, not installed in panel sections).https://www.instagram.com/11antgmxde/

In my opinion, you are defining it incorrectly. The precast concrete slab always needs to be complemented with cast-in-place concrete. What you are referring to, for example, are prestressed concrete precast slabs. However, their construction is completely different and they are not meant to be concreted on site (though they also have a chamfer, at least the ones I have seen so far).

Their construction is quite different and they are not filled with concrete on site (although they also have a chamfer, at least the ones I have seen so far )Yes, prestressed concrete precast slabs are, in that sense, "complete," since no additional cast-in-place concrete is required. A chamfer is safer: it does not weaken the component where that would be problematic and is less fragile than a right-angled edge, which is more prone to chipping.guckuck2 schrieb:
The precast slab always needs to be supplemented with cast-in-place concrete.Other semi-precast slab variants, like the ones I mentioned and also called precast slabs, have become less common on the market since the "filigree slab" gained popularity. It makes sense that the term, now "freed up" for new uses, is often used for filigree slabs from other manufacturers. "Precast slab" is a generic term and therefore not subject to trademark protection, but "Filigree slab (R)" is, as far as I know, a trademark of one manufacturer, and competitors probably want to avoid trademark infringement claims. Haha, I just noticed that the search function in the trademark register at DPMA is about as "in need of improvement" as this forum’s search function By the way, precast slabs as semi-precast slabs are also offered by several brick manufacturers, all of which need to be completed with cast-in-place concrete.

Could you show the image section in a larger context?What exactly should I photograph, or what are you interested in?
@Bookstar Thanks, okay 10 cm (4 inches). And how far does water travel in normal concrete?
