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. Influence of temperature on the adhesion of fibre reinforced polymers to timber surface
Resumo Os reforços de compósitos poliméricos com fibras de carbono (CFRP) e de vidro (GFRP) têm sido largamente usados em estruturas de madeira, onde eles podem estar expostos a condições adversas de temperatura. Para serem usados adequadamente, são necessárias informações sobre a sua adesão ao substrato. O objetivo desta pesquisa é avaliar a inf

4. Bond between steel and concrete made with ceramic waste aggregate
Abstract The reduction of natural resources combined with a substantial increase in the generation of solid waste in large urban centers, justifies the search for methods of reusing the construction industry waste. The ceramic industry has a high disposal rate during the manufacturing, transportation and eventual replacement of its products. In this case, re

5. 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

6. 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

7. Effect of Sonic Vibrations on Bond Strength of Fiberglass Posts Bonded to Root Dentin
Resumo Vibrações sônicas podem melhorar a resistência e a durabilidade da união de pinos de fibra de vidro, melhorando a penetração do sistema adesivo à dentina, bem como o escoamento do cimento. O objetivo deste estudo foi avaliar o efeito da vibração sônica na resistência de união de pinos de fibra de vidro à dentina radicular, através de en

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. Adhesion strategy and early bond strengths of glass-fiber posts luted into root canals
This study investigated the effect of coinitiator solutions and self-adhesive resin cement on the early retention of glass-fiber posts. Cylindrical glass-fiber posts were luted into 40 incisor roots with different adhesion strategies (n = 10): SB2, Single Bond 2 + conventional resin cement (RelyX ARC); AP, Scotchbond Multipurpose Plus (SBMP) activator + prim

12. Desenvolvimento de união de multimateriais através de rebitagem por injeção (Injection Clinching Joining) / Development of multimaterial joints through injection clinching joining
Multimaterial structures are currently a technologically attractive field of research. The growing use of polymer composites replacing metals in structures aiming for weight and emission reduction is part of the motivation of this study. The currently used techniques adhesive bonding and mechanical fastening are limited in certain aspects, opening a path for
