LIFE EXPECTANCY OF REINFORCED CONCRETE
| 项目名称： | LIFE EXPECTANCY OF REINFORCED CONCRETE |
| 摘要： | THE BEHAVIOUR OF THE OUTER LAYERS OF REINFORCED CONCRETE SUBJECTED TO NORMAL WEATHERING WAS STUDIED. EXAMINATION OF A NUMBER OF STRUCTURES SHOWED THAT CALCIFICATION COMES TO A HALT IN A GOOD CONCRETE DURING THE COURSE OF 20-110 YEARS AT A DEPTH OF ABOUT 14 MM. THE OLDEST STRUCTURES EXAMINED WERE 110 YEARS OLD, AND THE CONCRETE IS STILL IN GOOD CONDITION. TODAY ENVIRONMENTAL POLLUTION BY EXHAUST FUMES AND FURNACES ALSO HAS TO BE TAKEN INTO ACCOUNT. THESE EFFECTS WERE EXAMINED AND INFORMATION OBTAINED ON THE EXTENT OF DAMAGE CAUSED BY THEM. THE POSSIBILITY OF PROTECTING REINFORCED CONCRETE WAS STUDIED. PROVEN AND POSSIBLE LIFE EXPECTANCY OF PROTECTIVE TREATMENTS (LAYERS, COATINGS, GLAZES, IMPREGNATIONS) WERE ESTABLISHED. QUESTIONS RELATING TO PROTECTION AND REQUIREMENTS OF TREATMENTS WERE CONSIDERED. |
