Identification of steel bars immersed in reinforced concrete based on experimental results of eddy current testing and artificial neural network analysis
(2013-03-01)
This paper presents an experimental research on the use of eddy current testing (ECT) and artificial neural networks (ANNs) in order to identify the gauge and position of steel bars immersed in concrete structures. The ...

Bond tests and on-site structural concrete quality control
(2010-01-01)
Quality control of structural concrete has been conducted for decades using the axial compression test. The Pull-Out Bond test is suggested here as an alternative to the axial compression test of concrete. Well known and ...
Prestress losses in high performance lightweight concrete pretensioned bridge girders
(PRECAST/PRESTRESSED CONCRETE INST, 2005)
The purpose of this research was to determine the time-dependent behavior of high performance lightweight concrete and to examine how long-term behavior affects the prestress losses in high strength precast, prestressed ...
Steel bars identification in reinforced concrete structures by using ANN and magnetic fields
(2005-12-01)
This work proposes a methodology for non destructive testing (NDT) of reinforced concrete structures, using superficial magnetic fields and artificial neural networks, in order to identify the size and position of steel ...

Autocicatrização do concreto com diferentes tipos de cimentos em interação com catalizador cristalino
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia CivilUTFPR, 2019-06-26)
In a concrete structure, there are microcracks and cracks that have expected or unexpected characteristics. These microcracks may will be the way to external agents with degradation effect. For this reason, there is a need ...
Avaliação da eficiência do ensaio de aderência aço-concreto para estimativa da resistência à compressão axial do concreto
(Universidade Tecnológica Federal do ParanáPato Branco, 2014-07-30)
In the construction sector the quality control of products and services is done through supervision of works and testing of materials that require, in most cases, modern equipment and qualified professionals, where the ...
