Evaluating research on the utilization of recycled Brick aggregates in concrete

Abstract Considering the substantial production of concrete and the significant generation of demolition waste resulting from the dismantling of old concrete structures, the reuse of construction and demolition waste (CDW) has become crucial. Numerous studies have been conducted to assess the adequacy of the mechanical behavior of concrete incorporating CDW within the last two decades. However, there is a dearth of scientometric reviews on studies examining the environmental impacts of CDW. To address this gap, science mapping methods were utilized to conduct a bibliometric analysis of research on the environmental impacts of CDW. To conduct a comprehensive scientometric assessment of the utilization of recycled brick aggregates in concrete (RBAC) production, a search was performed in the Scopus database. The search primarily focused on the keywords "recycled bricks" and "concrete" to retrieve relevant papers. The objective of this study was to conduct a scientometric analysis of the bibliometric data on recycled bricks to identify its key components. The findings of this study included the following: (1) identifying the mostly focused area on the use of recycled bricks in concrete, (2) identifying authors with the greatest contribution, (3) journals with the most publications, (4) countries that contributed most in terms of publications, and (5) publications with highest number of citations. The findings suggest that the mechanical properties of RBAC have been the core of existing research. Existing studies have focused on the behavior of RBAC under monotonic loading only. The application of RBAC in structural contexts requires considerable attention, as prior research has yet to concentrate on this specific domain. No empirical research has yet explored the incorporation of recycled brick aggregate concrete in the presence of lap splices or within shear-dominated regions. Existing research has revealed substandard mechanical properties of RBAC that induce concerns for its structural applications. Given the state-of-the-art of RBAC and its applications, its behavior needs to be examined for reinforced concrete structural members. Moreover, the provisions of modern codes for RBAC also require significant attention. Moreover, the behavior of RBAC concrete under reverse cyclic loading needs attention.
