The requirements for the project will be specified in this paragraph.*Concrete finishes shall conform to the approved finishes. Finishin
33、g shall be accomplished at the time of concrete placement or immediately after formwork removal, as follows:a. Smooth finish: (1) As cast using flat smooth nonporous forms. (2) As cast using fluted, sculptured, board finish or textured form liners.b. Textured finish: (1) Textured form liners applied
34、 to inside of forms. (2) Distress finish by breaking off portion of face of raised portion of unit.c. Exposed aggregate finish: (1) Finish obtained by applying even coat of retardant to face of form, removing forms after concrete hardens, and exposing coarse aggregate to a depth of _ mm inches by wa
35、shing and brushing or lightly sandblasting away surface mortar.

37、re sealed, faces and other exposed surfaces of cast-in-place concrete shall be washed down, cleaned with soap and water applied with a soft bristle brush, then washed down again with clean water, or by other approved procedures. Discolorations which cannot be removed by these procedures, shall be co
38、nsidered defective work. Cleaning work shall be done when temperature and humidity conditions are such that surfaces dry rapidly. Care shall be taken during cleaning operations to protect adjacent surfaces from damage.3.5 SURFACE SEALINGAfter cleaning, exterior exposed architectural concrete surface
39、s indicated shall be given one coat of surface sealer, spray applied unless otherwise approved. Adjacent surfaces shall be protected to prevent damage from the surface sealer.3.6 PROTECTION OF WORKWork shall be protected against damage from subsequent operations.3.7 DEFECTIVE WORKDefective work shall be repaired or replaced, as directed, using approved procedures.- End of Section -SECTION 03 33 00 Page 7Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-
