Superplasticizing admixtures to control the heat of hydration of conventional concrete in urban buildings

Abstract

A systematic review was carried out on the influence of superplasticizing admixtures for the control of the hydration heat of conventional concrete, focused on decision making in construction processes of urban buildings during the period 2012-2022, through the identification of research papers published in high impact indexed journals such as Scopus, ScienceDirect, Tylor & Francis, Ebsco and Proquest. The study was carried out by applying certain search parameters that allowed the analysis of a total of 10 026 publications, which were organized according to their distribution by year of publication, country of origin, area of knowledge and type of publication. In this way, a bibliometric analysis was carried out, obtaining that, with 615 publications, China is the Asian country with the highest number of records during the period indicated, with the year 2021 being the period with the highest number of publications, 236 articles published. The area of knowledge with the highest number of bibliographic contributions was Engineering, with 44 % of the contributions. Once the information was organized through the necessary figures and tables, a bibliographic analysis was carried out taking into account some examples as contributions in the bibliography of some authors in each of the aspects studied, with the purpose of knowing their position on the proposed topic, concluding that: Through the use of superplasticizing admixtures it is possible to control the hydration heat of the concrete mix, reduce the amount of cement per m3, as well as, speed up the construction process on site.
