THE REGULARITY OF CONCRETE FLOOR SURFACES: A SURVEY OF CURRENT KNOWLEDGE

AN EXAMINATION OF ARTICLES, ADVISORY PUBLICATIONS, CODES OF PRACTICE, STANDARDS, TRADE LITERATURE AND RESEARCH REPORTS YIELDED VERY LITTLE INFORMATION ON THE SURFACE REGULARITY OF CONCRETE FLOORS. A VALUABLE ASSESSMENT OF CURRENT VIEWS WAS, HOWEVER, PROVIDED BY A SEMINAR OF PEOPLE CONCERNED WITH FLOOR CONSTRUCTION, AND USEFUL DATA WERE OBTAINED FROM A SURVEY OF SURFACE REGULARITY CARRIED OUT ON 13 CONCRETE FLOORS USING A BEAM PROFILOMETER DEVELOPED BY THE CEMENT AND CONCRETE ASSOCIATION. VARIOUS METHODS OF SPECIFYING AND CHECKING SURFACE REGULARITY ARE EXPLAINED. THE STANDARDS OF SURFACE REGULARITY AT PRESENT ATTAINED ON DIFFERENT TYPES OF FLOOR ARE SELDOM KNOWN BUT RECENT EVIDENCE SUGGESTS THAT THE TOLERANCES RECOMMENDED IN CP 204 MAY BE THE CLOSEST WHICH CAN REASONABLY BE EXPECTED ON MOST FLOORS. THE MOST COMMON TYPES OF IRREGULARITY OCCURRING ON CONCRETE FLOORS ARE DISCUSSED. RECOMMENDATIONS ARE MADE FOR IMPROVING SPECIFICATIONS FOR FLATNESS, FOR THE PROVISION OF LEVELLING DEVICES ON EQUIPMENT, AND FOR THE USE OF CONSTRUCTION TECHNIQUES WHICH MINIMISE SURFACE IRREGULARITIES. IT IS ALSO RECOMMENDED THAT FURTHER WORK SHOULD BE CARRIED OUT TO ESTABLISH THE DEGREE OF SURFACE REGULARITY REQUIRED ON DIFFERENT TYPES OF FLOOR AND TO DETERMINE THE EFFECTS OF VARIOUS CONSTRUCTION AND FINISHING TECHNIQUES. THERE IS A NEED FOR IMPROVED METHODS OF SPECIFICATION AND FOR ADVISORY LITERATURE IN ACCORD WITH CURRENT OPINIONS AND PRACTICES. /AUTHOR/
