Surface Preparation of Concrete
|Publication Date:||1 January 1997|
This standard gives requirements for surface preparation of concrete by mechanical, chemical, or thermal methods prior to the application of bonded protective coating or lining systems.
The requirements of this standard are applicable to all types of cementitious surfaces including cast-in-place concrete floors and walls, precast slabs, masonry walls, and shotcrete surfaces.
An acceptable prepared concrete surface should be free of contaminants, laitance, loosely adhering concrete, and dust, and should provide a sound, uniform substrate suitable for the application of protective coating or lining systems.
When required, a minimum concrete surface strength, maximum surface moisture content, and surface profile range should be specified in the procurement documents (project specifications).
The mandatory requirements of this standard are given in Sections 1 to 7 as follows:
Section 1: General
Section 2: Definitions
Section 3: Inspection Procedures Prior to Surface Preparation
Section 4: Surface Preparation
Section 5: Inspection and Classification of Prepared Concrete Surfaces
Section 6: Acceptance Criteria
Section 7: Safety and Environmental Requirements
Appendix A does not contain mandatory requirements.
