“…Naubi et al [79] developed the watershed sustainability index (WSI) for the identification of the problematic areas within the watersheds. De la Fuente et al [80] developed a method for analyzing the sustainability of different concrete and reinforcement configurations for segmental linings of tunnels. Arroyo et al [81,82] compared different decision-making approaches applicable for design decisions involving sustainability factors in architecture, engineering and the construction industry.…”

Sustainable decision-making in civil engineering, construction and building technology can be supported by fundamental scientific achievements and multiple-criteria decision-making (MCDM) theories. The current paper aims at overviewing the state of the art in terms of published papers related to theoretical methods that are applied to support sustainable evaluation and selection processes in civil engineering. The review is limited solely to papers referred to in the Clarivate Analytic Web of Science core collection database. As the focus is on multiple-criteria decision-making, it aims at reviewing how the papers on MCDM developments and applications have been distributed by period of publishing, by author countries and institutions, and by journals. Detailed analysis of 2015-2017 journal articles from two Web of Science categories (engineering civil and construction building technology) is presented. The articles are grouped by research domains, problems analyzed and the decision-making approaches used. The findings of the current review paper show that MCDM applications have been constantly growing and particularly increased in the last three years, confirming the great potential and prospects of applying MCDM methods for sustainable decision-making in civil engineering, construction and building technology.

“…Throughout the project of tunnel lining in Barcelona, De La Fuente and his assistants aimed to assess the sustainability of different concrete and reinforcement alternatives to be used in concrete [7]. In this project, they wanted to compare between vibrated fiber reinforced concrete (FRC), self-compacting fibre-reinforced concrete (SC-FRC) and conventional reinforced concrete (CRC).…”

The objective of this research paper is to discuss the main requirements which may affect the sustainability of concrete structures and develop the relative weights of these requirements. A questionnaire survey was conducted among construction experts, such as college staff, contractors and construction engineers. The survey was conducted to identify the relative weights of the concrete sustainability requirements. After reviewing literature, fifty nine factors which affect the concrete sustainability were prepared and divided them into 12 categories. A pilot study was conducted by 19% of sample size to enhance the questionnaire design. The pilot study was filled out by 10 college professors and 9 engineers with experience more than 10 years. This study helped us to modify the requirements which were directly connected with the concrete sustainability. Researchers found that the most important factors were related to "Aggregate" category. Aggregate category has the weight of 17.64% and waste category has the weight of 13.04%. These two categories have about 30% of concrete sustainability weight. The Green Pyramid Rating System (GPRS) was used in the present research to know what could be added.

The current infrastructure boom combined with the latest outcomes from 26th UN Climate Change Conference of the Parties (COP 26) seeking a carbon neutral society by 2050 have driven the increasing need for sustainable alternatives to be considered in construction. One such alternative is macro synthetic fibers, which have been gaining acceptance on major infrastructure projects. However, only limited uptake has occurred in permanent structures, due to a lack of knowledge around the behavior of macro synthetic fiber reinforced concrete (MSFRC) when exposed to elevated temperatures. Existing Australian and international design standards do not take into account the loss of strength for MSFRC after exposure to elevated temperatures. Hence, this systematic review sets out to combine all the existing knowledge on the mechanical properties of MSFRC and lay the groundwork for determining acceptable
