NDT assessment of concrete structures. Limehouse link tunnels
Assessing the durability of concrete has become an important function of engineer's responsibility for maintaining concrete structures. Bridge engineers have been at the forefront of emerging technology relating to their durability, as bridges are particularly susceptible to deterioration due to often-harsh environments. With the growth of non-destructive testing (NDT) over the past 25 years a bewildering array of tests has appeared. Within the industry detailed knowledge of the tests has not always kept pace with the growth, as engineers have struggled to keep abreast of increasing complexity. Because of this testing quality and interpretation of results have suffered, compounded on occasion by insufficient knowledge of such specialised techniques by those supervising the work. Appropriate advice is not readily available being spread amongst many different specifications and references some of which outdated. In order to make the step from knowing, for example, that destructive contaminants are present in the concrete, to selecting the best methods for repair, engineers require guidance on techniques available both for condition assessment and for interpretation of the data. This paper discusses NDT techniques available to assess the condition of structures and provide the fullest information enabling effective repair strategies to be developed show casing current methods attempting to manage the inevitable deterioration of concrete structures.
