      Dear engineers,
      normally when the grades of concrete are different for columns and beams,what we do is use the higher grade concrete for filling the column portion and allow this concrete to fill  the beam portion with 45 degree dispersion.And after filling the columns place the concrete on the beam portion.
      Regards
      salim
