Bibliometric Study of the Use of Recycled Aggregates in the Manufacturing of Precast Concrete

Abstract

Efficient use of available resources, through the conversion of produced waste into secondary raw materials, has become a priority of the EU's Waste Policy. Most notably in the Building Industry, the use of recycled materials depends mainly on its application. It is for this reason that the non-structural concrete precasts are such an attractive opportunity, mainly due to their less stringent requirements. The use of bibliometric tools has allowed analysing, quantifying and visualising the conceptual and social aspects of the scientific field ``precast concrete with recycled materials''; as well as identifying longitudinal trends in the most prevalent research topics in this field and its connection with other areas of study. Accordingly, this communication shows the first bibliometric analysis of the area of study under investigation. Through said analysis, it has been found that the interest in this field has been growing (number of industry-related publications) due to the negative environmental impacts linked to the sector. In addition, it has allowed us to identify possible gaps concerning the use of recycled materials in applications for which, at present, no published material exists.
