Purpose – To analyze the evolution of Environmental, Social and Governance (ESG) and innovation in the civil construction industry, focusing on innovative and sustainable practices, as well as ways of measuring the level of construction companies in these themes. Design/methodology/approach – A Systematic Literature Review approach was used. The Web of Science and Elsevier Scopus Databases, from 2017 to 2022, were used for data collection, based on a set of keywords and Boolean operators ("sustainable development" & "framework" & "measurement" & "environment”). Using the Zotero Software, 488 papers were classified and organized according to the publication date, main content, proposals for sustainable and innovative tools and techniques. The papers were analyzed in the VOSviewer Software. Findings – There is an Asian predominance in the volume of publications and networks of strong connections in clusters by countries. The authors tend to look for papers from the same region as a reference, going against the concept of globalization of ESG and innovation themes and the condition of replicability of practices. Among the exemplified practices, there are replicable models and initiatives, as well as incipient innovative construction materials and methods in search of consolidation. Originality/value – Amid the current and growing discussion about innovation and ESG in organizations, it is noted that the civil construction sector still lacks better performances in these themes. This paper aims to contribute to the advancement of the discussion in the sector, bringing together works found in recent literature.

Geopolymer concrete with time is gaining recognition as a sustainable alternative to Portland cement concrete, offering lower carbon emissions and utilising industrial by-products. While prior research focussed on its mechanical properties for structural purposes, this study explores its potential for paving applications. A unique geopolymer concrete mixture suitable for paving, referred to as paving quality geopolymer concrete (PQGC), was developed by incorporating slag sand (SS) as a substitute for river sand (RS). The investigation primarily assessed fatigue life PQGC mixes. The findings demonstrate that the inclusion of SS in PQGC has no significant impact on its setting times or workability. However, PQGC formulated with 100% SS, w.r.t PQGC containing RS, exhibited enhanced mechanical strength of 7% in compression, 16.7% in flexure and 8.3% in split tensile tests at 28 days of open-air curing. Following a 14-day period of curing, PQGC achieved a compressive strength of 46 MPa, surpassing the minimum requirement of 40 MPa as per IRC:58 2015 for pavement quality concrete (PQC) by 15%. To evaluate fatigue performance, PQGC beam specimens were subjected to repeated loading at stress levels ranging from 0.9 to 0.6. The resulting fatigue data were employed to develop stress-fatigue life (SN) and Weibull two-parameter fatigue failure models. Comparative analysis with fatigue failure models such as Indian Road Congress (IRC) and Darter revealed that PQGC exhibits superior fatigue resistance and longer life expectancy compared to PQGC. In conclusion, this study confirms that PQGC incorporating SS is an efficient and eco-friendly choice for constructing rigid pavements with advantages such as curing without water, enabling early opening of roadways to traffic, and excellent resilience under cyclic loads.

This manuscript highlights the mechanical, economical, ecological, and thermal investigations performed on paving quality geopolymer concrete (PQGC) incorporating processed steel slag (PSS) as a substitute for river sand (RSa). The replacement of RSa with PSS ranged from 0 to 100% in the PQGC mix. The mix with 100% PSS content exhibited enhanced geopolymerization, resulting in a denser and more amorphous matrix. This improved the mechanical properties, increasing compressive strength by 10.9%, flexural strength by 23.5%, and splitting tensile strength by 8.3%. The replacement of RSa with PSS in PQGC led to a marginal reduction in (embodied energy) EE and CO2 emissions. However, compared to conventional Pavement Quality Concrete (PQC) and Fly Ash PQC (FPQC), the reduction in EE for PQGC was 44% and 34%, while the CO2 emissions of PQGC were reduced by 1.22 and 1.49 times. Despite these benefits, PQGC with 100% PSS was 19% and 30% more expensive than PQC and FPQC, respectively. The Global Warming Potential (GWP) of PQGC was approximately one-third that of PQC and FPQC at all levels of replacement of RSa in PQGC when compared to PQC and FPQC. Additionally, thermal conductivity decreased from k = 0.67 W/m °C to k = 0.51 W/m °C with 100% replacement of RSa, keeping the concrete cooler. Therefore, PQGC with 100% PSS, when practically implemented, may help reduce surrounding temperatures. This study concludes that PSS is a feasible and reliable alternative to RSa, enhancing the sustainability of PQGC.
