Preface.(International Conference on Durability of Concrete)(Brief Article)
March 1, 2001... As part of the Fifth CANMET/ACI International Conference on Durability of Concrete in Barcelona from 4 to 9 June 2000, there was a special technical session on `near surface tests for the assessment of strength and durability of concrete'....

Why assess the properties of near-surface concrete?
March 1, 2001... Abstract The deterioration of concrete structures is a major problem in many countries throughout the world. This has prompted the search for methods of predicting the service life of both existing and new structures. Current prediction...

Reliability of partially-destructive tests to assess the strength of concrete on site.
March 1, 2001... Abstract The range of available tests for assessing the strength of insitu concrete based on measurements of surface zone properties is examined, together with developments in supporting documentation. Attention is concentrated upon a...

Assessment of the durability of concrete from its permeation properties: a review.
March 1, 2001... Abstract Concrete is a versatile and most popular construction material. Its long-term performance depends on the interactions with the service environment, in which the penetration of deleterious substances is highly significant. The...

Near-surface moisture gradients and in situ permeation tests.
March 1, 2001... Abstract Both the durability of concrete and permeation test results are influenced by the degree of saturation of capillary pores in concrete. In a laboratory, the moisture distribution of a test sample can be standardised by oven drying,...

Near--surface sensors for condition monitoring of cover-zone concrete.(Brief Article)
March 1, 2001... Abstract With more demands being made on reinforced concrete, 100-year guarantees of durability will become a necessity. Lifetime calculations, and prediction of the residual service-life of structures, require quantitative information on...

Test methods for on site measurement of resistivity of concrete -- a RILEM TC-154 technical recommendation.
March 1, 2001... Abstract This paper describes methods to assess concrete resistivity on site for various purposes related to corrosion and protection of reinforcement. It is based on the first draft of a forthcoming RILEM Technical Recommendation. The...

Half-cell potential mapping to assess repair work on RC structures.
March 1, 2001... Abstract Rational, cost effective strategies for the repair and rehabilitation of bridge components have to be based on reliable information on the level and rate of deterioration. Rapid, non-destructive techniques such as half-cell...

On-site measurements of corrosion rate of reinforcements.
March 1, 2001... Abstract The increasing number of structures suffering corrosion makes the study of their structural safety of importance. The assessment of the residual load-bearing capacity based on the quantification of the actual degree of damage and...
