On one of my recent jobs, a newly hired rod buster apparently misunderstood his task. Instead of greasing the forms for ease in removal, he GREASED ALL OF THE REBAR!!!! The reinforcement was for a continous footing and wall foundation for a 4-story building. The field engineer ordered all of the rebar to be removed and replaced or cleaned to his satisfaction. Unable to remove the grease, all of the rebar was re-installed. I have seen rebar greased before but only in greased caps at expansion joints. Obviously the grease would have an effect on the bond with the concrete. However, if placed in the correct location it should still take the tension forces for which it was intended. Any thoughts on this?
