Design and Development of an In-situ Chloride Migration Test
… determination of this parameter requires a long test duration and, hence, migration test methods have been developed. The principle of migration tests is to accelerate the transport of chlorides through concrete by the application of an electrical potential difference. However, no migration test …

Development of a new test protocol for the permit Ion migration test
… is to remove cores from the structure and test them in a laboratory to determine the chloride diffusion coefficient using the steady state diffusion test. This test is not popular due to its long test duration to achieve a steady state of flow of chlorides through the test specimen, which …

Enhancing the service life of concrete exposed to chloride attack
… degree of accuracy, four contemporary chloride test methods were used in this work to measure the chloride penetration of concrete, which are: (i) Method A-rapid chloride permeability test to ASTM C1202; (ii) Method B-chloride migration test to NT Build 492; (iii) Method C-Multi-Regime test to …

Rapid assessment of the potential chloride resistance of structural concrete
… the three allowed methodologies, the immersion test was carried out. At least two water-cement ratios were produced for each mix design to enable normalisation of the results. The performance of concrete was compared on the basis of equal compressive strength, i.e. 40 and 50 N/mm2 and an equal …

Durability Assessment and Service Life Prediction of Concrete in Extreme Aggressive Environment
… Resistivity (SR) and Bulk Resistivity (BR) tests, which will be used to qualify concrete mixes used in in extremely aggressive chloride environments. To achieve these objectives, the research uses a systematic approach that combines experimental testing with analytical modeling. Different …

Movement ecology of two threatened anadromous species, twaite shad Alosa fallax and sea lamprey Petromyzon marinus, revealed by acoustic telemetry.
… and space use during both freshwater spawning migrations and the marine life-phase is poorly understood, compared with anadromous species of the Salmonidae family. Here, the movement ecology of threatened twaite shad Alosa fallax (‘shad’) and sea lamprey Petromyzon marinus was investigated …

Physical performance and durability evaluation of rubberized concrete
… procedure. Then, three types of durability test were conducted namely, 1) Chloride ion diffusion test, 2) Abrasion wear resistance test, and 3) Freezing and thawing test. Up-to-date, many successful achievements were reported by researchers around the world. However, in Asian cases, very …

Estrategias quimiométricas aplicadas a técnicas cromatográficas para el análisis de monómeros y aditivos
El eje central de la tesis de investigación consiste en la implementación de procedimientos analíticos, empleando como técnica de análisis la cromatografía líquida con distintos detectores (FLD y DAD), que presentan bajo impacto tanto medioambiental como económico. Los métodos desarrollados se han …
