STUDY OF PLASTIC COATED CONCRETE SURFACINGS

UNTERSUCHUNGEN AN KUNSTSTOFFBESCHICHTETEN

THE RESEARCH IS BEING CARRIED OUT UNDER A PARTIAL CONTRACT UNDER THE CONTRACT ENTITLED 'STUDY OF PLASTIC COATINGS ON CONCRETE PAVINGS' (BAST). IN COLLABORATION WITH THE BAST, THE LAYING OF THE COATING IN THE FIELD IS BEING OBSERVED AND EVALUATED. THE AFMPA IS ALSO CARRYING OUT STUDIES OF THE SYNTHETIC RESINS AND PLASTICS MORTARS USED IN THE FIELD, IN ORDER TO COMPARE THE REQUIREMENTS LAID DOWN IN THE DRAFT SPECIFICATION WITH THE VALUES ACHIEVED IN CONJUNCTION WITH THE BEHAVIOUR OF THE COATINGS UNDER TRAFFIC. THE PRINCIPLE VALUES TO BE DETERMINED ARE: LINEAR SHRINKAGE, TENSILE AND BENDING STRENGTHS, IMPACT STRENGTH, WATER ABSORPTION, COEFFICIENT OF EXPANSION, IR DIAGRAM, RESISTANCE TO TEMPERATURE CYCLING OF COATED SLABS.
