DURABILITY OF CONCRETE STRUCTURES IN DENMARK

THIS STUDY IS A COMPREHENSIVE DESCRIPTION AND EVALUATION OF THE DURABILITY OF CONCRETE STRUCTURES IN DENMARK AND OF THE PHENOMENA OF THE FIELD DETERIORATION OF CONCRETE. DOCUMENTARY REPORTS AND ARTICLES PREVIOUSLY PUBLISHED FORM THE BASIS OF THE STUDY, BUT EXAMINATIONS FROM RECENT YEARS WORK ARE ALSO INCLUDED. THE METHODOLOGY DEVELOPED FOR THE STUDY REPRESENTS AN ATTEMPT TO CREATE A SYSTEMATIC COMBINATION OF: SURVEY INSPECTIONS OF CONCRETE STRUCTURES, DETAILED FIELD EXAMINATIONS OF SELECTED STRUCTURES, MACROSCOPIC EXAMINATIONS OF CONCRETE SPECIMENS, AND THIN SECTION EXAMINATIONS. TYPICAL SYMPTOMS OF FIELD DETERIORATION ARE DESCRIBED, AND THE EXTENT TO WHICH THE FEATURES OF DETERIORATION CAN BE CORRELATED WITH THE POTENTIAL CAUSES OF DETERIORATION SUCH AS ALKALI-AGGREGATE REACTIONS, FROST, AGEING, SHRINKAGE ETC. IS DISCUSSED. THE GREATER PART OF THE EXAMINED CONCRETE HAS BEEN EXPOSED TO COMBINE INFLUENCES OF THESE AGENTS DUE TO THE NATURAL CONDITIONS IN DENMARK. BUT SPECIMENS PRECLUDED FROM THE ACTION OF ONE OR SEVERAL OF THESE AGENTS, ARE ALSO INCLUDED IN THE INVESTIGATIONS, AND HAVE BEEN VALUABLE FOR COMPARISON. DIAGNOSES OF THE DETERIORATION OF SEVERAL STRUCTURES EXAMINED BY THE WRITER ARE GIVEN. IT IS EMPHASIZED THAT THESE DIAGNOSES STILL CONTAIN A GREAT DEAL OF PERSONAL JUDGMENT ON ACCOUNT OF THE LACK OF DATA ON CONCRETE CHARACTERISTICS, EXPOSURE ETC., AND DUE TO THE LACK OF KNOWLEDGE CONCERNING FUNDAMENTAL ASPECTS OF THE PROCESSES OF DETERIORATION AND THEIR INTERDEPENDENCE. /AUTHOR/
