patch with nonshrink grout. Patch tie holes and defects when the forms are
removed. Concrete with extensive honeycomb including exposed steel
reinforcement, cold joints, entrapped debris, separated aggregate, or other
defects which affect the serviceability or structural strength will be
rejected, unless correction of defects is approved. Obtain approval of
corrective action prior to repair. The surface of the concrete shall not
vary more than the allowable tolerances of ACI 347R. Exposed surfaces
shall be uniform in appearance and finished to a smooth form finish unless
otherwise indicated.
[3.5.2
Not Against Forms (Top of Walls)
Finish surfaces not otherwise specified with wood floats to even surfaces,
and match adjacent finishes.
]3.5.3
Formed Surfaces
3.5.3.1
Tolerances
ACI 117 and as indicated.
3.5.3.2
As-Cast Rough Form
Provide for surfaces not exposed to public view. Patch holes and defects
and level abrupt irregularities. Remove or rub off fins and other
projections exceeding 6 mm 0.25 inch in height.
3.5.3.3
As-Cast Form
Provide form facing material producing a smooth, hard, uniform texture on
the concrete. Arrange facing material in an orderly and symmetrical manner
and keep seams to a practical minimum. Support forms as necessary to meet
required tolerances. Material with raised grain, torn surfaces, worn
edges, patches, dents, or other defects which will impair the texture of
the concrete surface shall not be used. Patch tie holes and defects and
completely remove fins.
3.5.4
[_____] Finish
**************************************************************************
NOTE: Add information where special type of finish
is desired. Refer to ACI 301 for information on
smooth rubbed finish, grout cleaned finish, cork
floated finish, and exposed aggregate. Areas
requiring special finish should be clearly
indicated. Coordinate with the specifications.
**************************************************************************
Provide concrete indicated with a [_____] finish as follows:
[_____].
[3.5.5
Surface Finish Samples
**************************************************************************
NOTE: Include when either job complexity or
aesthetics justify the additional cost associated
with these requirements.
**************************************************************************
Provide
a minimum of three sample concrete panels for each finish for each
