2. Numerical approach of the steel-concrete bond behavior using pull-out models
ABSTRACT This paper deals with the analysis of monotonic loading behavior in pull-out tests. The main objective is to obtain a reliable numerical model to represent the steel-concrete bond behavior using previously obtained experimental results. The tests were performed in RILEM pull-out specimen using 10 mm steel bar and concrete with compressive strength o

3. Caracterización de resinas epoxi para uso en conectores de ductos flexibles
ABSTRACT In the offshore productions of gas and oil are frequently used flexible pipes. The end fitting is the connection between the flexible pipe body and the production unit, at the assembly of this component is used epoxy resin to fill the free space inside it. This polymeric material holds the tensile armor wires to form the anchoring system. A critical

4. Influencia de la temperatura en ensayos de arrancamiento sobre diferentes sistemas epoxi-acero de uso en conectores de ductos flexibles
ABSTRACT In the offshore oil fields located in deep and ultra-deep waters they are used flexible pipes. In many cases inside these pipes, the hydrocarbons are transported at elevated temperatures. At the ends of the flexible pipes are installed end fittings, these are the connection with sea platforms and different subsea systems. In the assembly of end fitt

5. Interfacial Shear Stress with Pull-out Test at Zeolite Ceramic Matrix and SS316 Single Fiber
ABSTRACT Natural zeolite ceramic is a material that can be used as bioceramics but it is fragile to crack. The weakness of ceramics can be overcome by making ceramic metals. The use of SS316 (stainless steel 316) fiber to strengthen the zeolite ceramic had been done in order to determine the interfacial relationship by using a fiber pull-out test. The conten

6. Experimental Study of the Compressive Strength of Multi-Coat Renders
Mortar compressive strength is a standard requirement and should be tested on stand-ardized specimens with a 40 mm square cross section. However, these specimens with only one type of mortar (base-coat layer) do not represent the render traditionally ap-plied to façades since that must consist of at least two layers (base coat and top coat, with different f

7. Experimental Investigation of Steel-Concrete Bond for Thin Reinforcing Bars
Abstract The steel-concrete bond is a fundamental property in reinforced concrete structures. Although there are several studies on the steel-concrete bond, few of them have evaluated the performance of reinforcing bars with diameters less than 10.0 mm, which includes 5.0, 6.3, and 8.0 mm diameters, which are normally used in reinforced-concrete elements. Th

8. Does MTA affect fiber post retention in repaired cervical root canal perforations?
Abstract This study evaluated the effect of mineral trioxide aggregate (MTA) on the retention of fiber posts in repaired root canal perforations. Ten-millimeter post spaces were prepared in 60 endodontically treated bovine incisors. Root perforations were created in half of the root canals in the cervical area prior to being filled with white MTA-Angelus. Fi

9. The Bond Strength Behavior of Polymer-modified Mortars During a Wetting and Drying Process
Polymer-modified mortars are highly popular for setting exterior tile systems and low-porosity ceramic tiles because they possess greater flexibility and higher bond strengths than conventional mortars which increases cladding serviceability. However, the long-term performance of this application is not completely understood and many pathologies has been rep

11. Ensaios de arrancamento e cisalhamento em descontinuidades simuladas reforçadas com barras de aço / Pull-out and shear tests on discontinuities reinforced with steel bars
Ancoragens são muito utilizadas na estabilização do maciço rochoso pela rapidez e baixo custo, embora sua análise não seja completamente entendida devido à interação de diferentes materiais como rocha, graute e aço. Este documento apresenta os resultados de um estudo realizado em juntas lisas reforçadas com ancoragens. Foram ensaiadas ancoragens c

12. Implementação de ensaios de arrancamento cíclico de geossintéticos / Implementation of cyclic pull out tests of geosynthetics
Os ensaios de arrancamento cíclicos são utilizados para avaliar o comportamento de sistemas de solo reforçado quando submetidos a carregamentos cíclicos, podendo ser aplicados na área de pavimentos reforçados com geossintéticos ou em comportamento sísmico de solos reforçados com geossintéticos. O comportamento de sistemas de solo reforçado submeti
