Hi,
in other forums and on the internet, I often read that steel fiber reinforced concrete slabs are rather unpopular, especially for residential buildings. However, I can’t quite understand the reason from the technical jargon.
We also have a steel fiber concrete slab, and whether it’s good or bad – we have to deal with it now. Our structural engineer added conventional reinforcement steel in one area (about one-third of the total surface). Otherwise, the description seems quite sparse, so I hope it holds up:
Now the question is, what is the problem with steel fiber reinforced concrete (SFRC)? Does it crack?
It needs to last 50 years, after that I don’t care. Is that realistic?

- Total area 110m² (1,184 ft²)
- Thickness 15cm (6 inches)
- Concrete grade: C 25/30 XC4 XF1 XA1
- Fiber content of 20kg/m³ (1.3 lb/ft³)
- Structural design
Now the question is, what is the problem with steel fiber reinforced concrete (SFRC)? Does it crack?

I don’t understand why you are asking this question after having signed your construction contract?
Best regards, Bauexperte

It would be interesting to know which provider you signed with and under what conditions...Specific company names are only to be discussed in the private Prime forum. I don’t want to register there. Also, I don’t want to criticize a company without having good knowledge. Apparently, there are load-bearing and non-load-bearing concrete slabs? Since we have a perimeter foundation below, I hope the load on the slab will not be too high.
