“…And Doostmohamadi, A., Karamloo, M., & Afzali-Naniz, O. (2020) [50] discover that using polyolefin macro fibers with two friction volume (0.3% and 0.5%) by volume of self-compacting lightweight concrete improved the bond strength between GFRP bars coated with sand (8mm diameter) and self-compacting lightweight concrete (36MPa and 40MPa) and stated that the use of fibers restricts the longitudinal parallel cracks to the bar and splitting failure will not observed in concrete specimens in the present of fibers within concrete mixes.…”

Nowadays, lightweight concrete become popular among construction companies due to its physical characteristic such as sound and thermal insulation, lightweight, cost and environmental saving, self-levelling…etc., which make it an attractive choice as a building material. However, this concrete face many constructional obstacles due to the lack of adequate and sufficient constructional information about the nature of this concrete. This requires great caution when use it for structural purposes. Among these great constraints, for example, is the weak characteristic of the bond between this concrete and reinforcing steel. Therefore, in order to get rid of these defects of concrete and make it usable in various construction sectors, this paper summarizes researchers works concerning bond behavior between light weight concrete and reinforcing bars , the variable influencing bond behavior such as; concrete type, rebar type and diameter, W/C ratio, and adding fibres. And results collected from experimental work with most important conclusions

The increasing demand for river sand, driven by infrastructure development, poses environmental challenges. The study aims to address the depletion of river sand by integrating sea sand as a fine aggregate in the production of Self-Compacting Concrete (SCC) through a Systematic Literature Review. Furthermore, it includes an in-depth bibliographic analysis of relevant literature using VOSviewer to generate network visualizations of author-co-citation and country-wise citations. The article offers diverse options for sustainable solutions to mitigate environmental impacts while meeting infrastructure demands. It focuses on assessing the durability of SCC incorporating sea sand through real-time monitoring with the Internet of Things (IoT) and employing artificial intelligence methods like PointRend and neural networks to study the properties of SCC utilizing sea sand. Subsequently, the study emphasizes the need to address river sand shortages in infrastructure development and provides insights for further research on enhancing the properties of SCC with sea sand.
