Casting slab under stove 20mm thick

[spocks_beard]

Hello

I am considering casting a slab under our cast iron stove as a spark guard and to compensate for the height against the surrounding parquet.
I'm wondering if it's sufficient to cast with fine concrete, or do I need to add reinforcement?
If so, which one?

I know there is fiber-reinforced self-leveling compound, could that be an alternative instead, considering the slab will be quite thin, and thereby avoid extra reinforcement?

Unfortunately, I have forgotten the name, but there is a type of board that you use against, for example, mustocken to not have anything combustible against it. It is sold in standard sheet sizes (1200x2400), and the thickness I looked at was 12 mm. Couldn't you just lay double of those under the stove? It would save a lot of work!

Unfortunately, I have forgotten the name, but there is a type of board that you use against, for example, the timber wall to not have anything flammable against it. It is sold in regular sheet sizes (1200x2400), and the thickness I looked at was 12 mm. Couldn't you lay double of those under the stove? It would save a lot of work!

Do you mean Minerit? http://www.beijerbygg.se/templates/BB_Produkt.aspx?id=35491

I would probably lay Minerit and then tiles.
How large is the area and what kind of substrate are you planning to cast on?
I assume it works well with fiber-reinforced self-leveling compound if the substrate is "dead."

That's right, that's what it's called!

We took a slate slab and sawed it to size. Sprayed it with clear varnish (it became darker and easier to clean). The edges consist of tyrkantsprofil that was split into two "L", varnished, and then mounted with silicone.

Nice! Good idea!
