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 ...
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 ...
Esclerometria como ferramenta de controle de qualidade para peças de concreto para pavimentação
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de Construção CivilEngenharia CivilUTFPR, 2015-11-17)
Although the term quality control has grown tremendously in recent centuries, it’s possible to see that humanity has always been concerned with this type of control, for example the Egyptian embalming. However, it is ...
Validation of Performance-Dependent Failure Criterion for Concretes
(American Concrete Institute, 2011-05)
This paper focuses on the reformulation of the internal functions of the performance-dependent failure criterion (PDFC) for concrete, proposed by the authors, and its validation for different concrete qualities and stress ...
Estudo comparativo de ensaios destrutivos e não destrutivos para concreto
(Universidade Tecnológica Federal do ParanáCuritibaDepartamento Acadêmico de Construção Civil, 2012-04-12)
Concrete is the most used material in construction and better suited to resist compressive loads. Since it an indispensable material and that in its aging is subject suffering from various types of conditions and with high ...
Avaliação da resistência à compressão do concreto usinado: comparação entre o método de moldagem remota e moldagem in loco
(Universidade Tecnológica Federal do ParanáPato BrancoConstrução Civil, 2014-12-02)
The use of ready-mixed concrete is increasing in the last decades, as the pressure from the market to use a high quality product, using less storage spaces and less production of residuals also increased. For the quality ...
