Since the advent of Portland cement , concrete structures has become one of the most commonly used in the construction project architectural forms . Hundred years , people have been studying the technology concrete structure detection , in order to grasp the concrete structure in the complex environment of the internal and external damage , the durability of concrete structures full , comprehensive and accurate assessment let the concrete structure to better serve the community in service period . Firstly the actual pier mathematical model assumptions detection , and compare them with the actual test results . In addition, through the use of on-site measurement method , the rebound method , wave velocity method wharf structure detection material properties data base so as to the assessment of the durability of the pier . Secondly , from the erosion of the concrete carbonation and chloride ions on the structure , impermeability and frost resistance , alkali - aggregate reaction and reinforced rust several aspects , careful analysis of the main factors that affect the durability of concrete structures , and raised in the method of improving the durability of concrete under various conditions . Analytic Hierarchy Process . This method starting from the the subkey project and unit cell division through the entire concrete structure , the assessment easy to carry out and achieve flexible , accurate assessment of the purpose . Actual situation proved that this method deserves promotion between the engineering and technical personnel in the field of civil engineering . Finally, the structure of the actual project durability assessment and life prediction . In conclusion , on the durability study the problems that currently exist and the future direction of development in this area some personal views .
