Abstract:
Q. My company is the general contractor on a midrise reinforced concrete building. The owner’s inspector is requiring us to remove concrete splatters on the column and wall dowels before we can install the forms for the next level. I have been in this business for more than four decades, and this is the first inspector that has required this action. We have to use wire brushes and grinders to remove the splatter. The splatter also roughens the bar surface, so I don’t understand how it could negatively affect bond. The inspector has cited ACI 301-101 as justification, specifically quoting Section 3.3.1.1: “reinforcement shall be free of materials deleterious to bond.” Is there a reference we can use to persuade the inspector that splatter is not deleterious to bond?
