      In one of my project I have Initial and final stressing , that is in two stages at 12mpa and 25 mpa strength.My question is if I dont do initial stress of 115 bar what will be the effect on the slab.If I apply directly 420 bar of final stress as i get 25 mpa

          im working in a company applying stresses on one stage (final only)
          as i see initial stressing was applied before bottom mesh is required in all slabs to prevent shrinkage cracks as my friend said before,
          but i see that bottom mesh is enough.
          if u r interested u can calculate shrinkage forces based on ACI code and check if bottom mesh is enough or not.

          best regards
