“…Then, the social life cycle assessment framework of different stakeholders has been established and analyzed based on the production of prefabricated building components [15]. With the deepening of research, the scope of the sustainability of buildings has been extended to the production of sustainable concrete [16,17], maintenance [18], and refurbishment [19] of buildings. After the independent study of various dimensions of building sustainability, comprehensive sustainability assessment received much more attention, especially building construction [20].…”

With the development of civil engineering sustainability, the scope of corresponding research covers a broader range. It is difficult for researchers to master the holistic situation of the study, leading to duplication and lag of their research. Therefore, this paper aims to present a state-of-the-art of the research of civil engineering sustainability by adopting two new methods (bibliometric and social network analysis) to review the literature of this field. It is concluded that the existing research takes engineering as the main subject to improve its sustainability through technologies. Current research mainly focuses on technological innovations and evaluations of environmental impacts in the fields of construction technology, energy consumption, material preparation, and design. The countries with the largest number of published articles are the United States and China. The Hong Kong Polytechnic University is the institution that has published more articles than others. Journal of Cleaner Production and Sustainability are the journals that have published the most articles. For the researchers, a professor of the University of Adelaide is the researcher who has published the most articles, and experts from South China University of Technology, Chongqing University, and University of Brighton are the main hubs among different researchers.

“…In tune with such trend, the quality of recycled aggregates [4] is being evaluated and studied in various aspects, and it is known that recycled aggregates demonstrate material performances that approximate those of natural aggregates. Therefore, the purpose of this study is to develop sustainable structural concrete [5] by evaluating the flexural performance of RC beam to which recycled aggregates are substituted 2 Advances in Materials Science and Engineering by 30% and by applying aramid fiber sheets by specifying the RC beam as reference specimen in order to provide comprehensive data for recycled aggregates and alternative resource to natural aggregates which are decreasing in reserve and to acquire reliability of it.…”

The purpose of this study was to evaluate the flexural performance of recycled aggregate RC beam reinforced with aramid fiber sheets. Compressive strength of concrete using recycled aggregate is generally similar or slightly lower than normal concrete. To improve the compressive strength, aramid fiber sheets have been used in this study. This study examines the structural behavior of concrete beams prepared with recycled aggregate and strengthened aramid fiber sheets at varying locations. One concrete beam as a control specimen, that is prepared with 30 percent recycled aggregate and 70 percent natural aggregate, has been tested, and 3 more strengthened beams (bottom, bottom and sides, bottom and both ends with U-shaped strengthened beams) are tested. The ultimate loads have increased by 38.01%, 39.88%, and 100.79% for bottom, bottom and sides, bottom and both ends with U-shaped strengthened beams. The ductility ratios are 2.75~6.20 for strengthened beams. The experimental results showed that the strengthening system with U-shaped band controls the premature debonding and provides a more ductile failure mode than the strengthening system without U-shaped bands. It can be found that the ultimate strength of H40-RGA30-BS specimen based on load-deflection curves shows most promising result. The experimental results are compared with the analytical results of nonlinear flexural behaviors for strengthened reinforced recycled aggregate concrete beam.

“…Portland limestone cement (PLC), as an alternative to Portland cement (PC), has been more widely used in European countries to reduce the energy use and emissions associated with cement manufacturing (Livesey, 1991). In the U.S. concrete industry, supplementary cementitious materials (SCMs), such as fly ash (FA), silica fume, and ground-granulated blast-furnace slag, have often been used to lower the environmental impacts from the use of Portland cement (Jin et al, 2015;Obla el al., 2012). Alternative aggregates like lightweight aggregate (LWA) and recycled concrete aggregate are also used to produce concrete for suitable applications (Jin et al, 2015).…”

Although these sustainable concrete materials have been individually investigated on how they could affect concrete properties, there are limited studies (e.g., Berry, 2011;Limbachiya et al, 2012) on how they can be jointly applied to further elevate the sustainability of concrete, not to mention wide industry applications.…”

Using environmentally friendly concrete materials can help improve the sustainability of the concrete industry. However, the effects of such materials on concrete properties must be fully understood before sustainable concrete can be widely applied. Previous research showed limited applications of statistical methods in analyzing the effects of sustainable concrete materials on fresh concrete properties. This study applies multivariate regression analysis to modeling properties of fresh concrete (i.e., slump, air content, and density) made with multiple sustainable raw materials based on variables in mixture design. Different regression models were tested to explore the best-fit model(s) that can capture and predict how these variables affect fresh concrete properties. The regression analysis showed satisfactory results in predicting air content and density, but not in predicting slump. The regression analysis, as a statistical tool, can provide deep insights into how the selected independent variables affect fresh concrete properties and the degree of the effects.
