What is considered an "intentionally roughened surface" per ACI318?
What is considered an "intentionally roughened surface" per ACI318?
(OP)
ACI 318 states for the purpose of shear friction the interface of hardened concrete should be roughened to an amplitude of at least 1/4". Does this need to be done using a tool? or can the surface be considered roughened if no finishing work is done and it naturally cures such that the aggregate extends out 1/4"?
My feeling is that the statement "intentionally roughened" means it needs to be done with a tool. I'm looking at a case where a concrete corbel is cast separately and "mucked" in to a concrete wall or spandrel pour in a precast plant.
