Column concrete pouring at site

Make your column shuttering with a window panel at 3 ft height interval.Put a patra made chute at the mouth of opening of window,pour concrete gamela filled in to this.Later vibrate,tamping for compaction.when you come to this height close the window panel,properly (with munda/jack munda/ pins, as per your shuttering done.) By doing this method segregation of concrete is avoided.
