Hi All,

I am looking at cast the "trough" of my outdoor BBQ out of
"concrete" (i.e. the bit where you light the charcoal). Can I used
normal concrete with some reinforcing bars? I have assumed not but
wondered if anyone had tried it?

I was pointed in the direction of "castable 1400" which is fine to
1400 deg c but this is very expensive (£25/ bag). I was also
wondering whether I switch regular cement with fondu cement and mix
the concrete as usual would work? Also, is it OK to use reinforcing
mesh/ bars? I was wondering whether they would expand within the
concrete as they got hot and crack the whole thing?

Any help appreciated.

thanks

Lee.
