“…The pull-out tests were conducted following a procedure similar to EN 10080:2005 [6] and the testing principle is shown in Figure 1. The method was chosen because it has been standardized and the experimental model can be performed relatively easily, suitable for available equipment.…”

Bond behavior between the reinforcement steel bars and surrounding concrete is considered as an important characteristic for reinforced concrete structures, including lightweight aggregate concrete ones. This paper presents an experimental investigation on the bond behavior of 14mm diameter steel bars embedded in lightweight aggregate concrete. The bond slip relationship between rebar and lightweight aggregate concrete shows a conventional behavior, similar to traditional reinforced concrete. The development length of 14 diameter steel embedded in lightweight aggregate concrete is smaller than the requirement in ACI 318-11.

“…Most of design standards, especially Vietnamese ones, regulate only the development length of reinforcement for traditional concrete. The paper introduces the empirical research according to EN10080:2005 [6] to determine the adhesive behavior between lightweight reinforced concrete and bars of diameter 14mm (14).…”

In recent decades, lightweight aggregate concrete (LWC) became a popular building material due to its desired properties. However, various attributes of LWC, such as bond behavior of used reinforcing, have not been described thoroughly. In this regard, LWC produced with 0%, 50%, and 100% expanded clay aggregate was designed, and the physical–mechanical properties were assessed for material characterization. Subsequently, the bond behaviors of LWC reinforced with steel, glass fiber reinforced polymer (GFRP), and basalt fiber reinforced polymer (BFRP) bars were evaluated by pull-out tests. The results of the experimental program allowed the effects of expanded clay aggregate incorporation on LWC properties to be quantified. The bond strength of BFRP bars was not affected by the replacement of coarse aggregate by expanded clay aggregate, whilst the GFRP bars showed lower bond strength values of LWC specimens. Contrarily, in the case of steel bars, both the bond strength and bond stiffness were higher for LWC specimens than for those of normal concrete. Finite element software ATENA 3D was used for simulation of the bond behavior of LWC, and the model validated by the experimental results referred to reasonably corresponding outputs.
