The Australian sprinkler code prohibits this. There are very good reasons for this. If you use steel pipe it will corrode and leak. If you use copper or plastic pipe it will be damaged during construction (bent or squashed during pouring of the concrete) and may leak or not allow the required amount of water to pass through. Any changes to sprinkler locations required due to later architectural changes are impossible to achieve. In the past when the code did not prohibit this some buildings were built with pipe cast into the slab. There were some disasters and 5 to 10 years later the buildings had to be retro fitted with pipe below the slabs due to leaks (very difficult jobs). I would not recommend casting sprinkler systems into slabs.
