“…Impact assessment is a key step in a LCA study which facilitates the understanding of emissions in terms of potential environmental impacts (Roh et al , 2017; Crenna et al , 2019; Sandanayake et al , 2019; Phrommarat and Arromdee, 2019; Wang et al , 2018). The selection of most suitable impact categories is based on the purpose of the LCA study and intended key decision making process.…”

PurposeThe main objective of the study is to present a systematic process that can assess, compare and benchmark different geographical levels environmental impacts of using sustainable materials at construction stage.Design/methodology/approachCurrent study presents a methodological framework to evaluate environmental impacts at the construction stage of using sustainable materials through a cradle-to-gate process based quantitative LCA study. Scenario analyses and an optimisation analysis using Monte-Carlo simulation are conducted to investigate the influence of external factors on environmental impacts at different geographical regions.FindingsMaterials account for 98% of greenhouse gas (GHG) emissions. Carbon monoxide (CO) and non-methane volatile organic compounds (NMVOC) record significant non-GHG emissions. Particulate matter (PM10) emissions are significant from transportation and equipment. High significance of global warming potential (GWP) (38.98%) and photochemical oxidation formation potential (POFP) (34.49%) at global level and eutrophication potential (EP) (52.83%) and human toxicity potential (HTP) (25.30%) impacts at local level were observed. Shortest transportation distance reduces 14.91% PM10 and 4.69% nitrous oxide (NOx) emissions. Inventory variations have major influence on POFP impact at global level. Local level impacts are not significantly affected by inventory variations. Optimisation analysis indicated, high fly ash in concrete increase local level carbon emissions, if OPC concrete transportation distance is less than 23.7 km.Research limitations/implicationsUse of case-specific information for validation may lack generalisation. However, methodology can be used for future sustainable decision making over using sustainable materials in construction.Originality/valueThe study estimate environmental impacts at different geographical levels when sustainable materials are used for construction.

“…The Life Cycle Inventory of the prestressed concrete slab included: (a) quantity of raw materials (active reinforcement steel); (b) electricity consumption (pre-tensioning machines, use of cranes, and steel cutting machines); (c) fuel consumption for transporting materials. For the amount of energy related to the pre-tensioning process, a prestressed concrete pole industry was adopted as a reference, detailed in the studies by Phrommarat and Arromdee [65]. This item comprehends the life cycle stage from the exit of the prestressed slabs from the manufacturing site to the installation on the bridge.…”

The construction sector is responsible for some of the highest energy and natural resources consumption. In this context, new materials and solutions are created aimed at developing sustainable alternatives. While the literature presents papers that evaluate the mechanical and durability properties of concrete with glass waste powder and account for its environmental impact, no papers have executed the evaluation considering the retrofit of bridges. Furthermore, no papers evaluating the materials, construction, and maintenance could be found. Hence, this study proposes a technical and sustainable solution for the retrofit of the Third Bridge of Vitoria, an important intercity urban connector. This study evaluates both the technical and the environmental performance of structural concrete elements, considering the partial substitution of cement with glass waste powder and a baseline scenario with conventional concrete. The environmental impacts were evaluated through the life cycle assessment tool. The results indicate that incorporating waste glass powder in the prestressed hollow-core slabs as a partial cement replacement can improve the durability-related properties and mitigate environmental impact. It also shows that the manufacturing phase is the most impactful and that glass powder can significantly reduce the impact of maintenance.

“…At present, research on electric poles has gradually shifted from traditional materials to composite materials [23]. Shakespeare Company in the United States successfully developed composite distribution poles and transmission poles from 1993 to 1995 [24,25], but the development and application of composite electric poles still have constraints such as cost and versatility.…”

Concrete poles play an important role in distribution networks and are prone to degradation due to environmental influences. Fracture failures primarily result from structural deterioration, including both damage to the concrete structure under stress overload conditions and the deterioration of the concrete material itself. Due to the lower tensile strength compared to compressive strength, concrete structures often exhibit cracking and fractures. This study initially analyzes the structural deterioration process of concrete electric poles and subsequently develops a damaged model using the finite element method. The results reveal that the maximum tensile strength of concrete electric poles occurs at 2.4 m, while the compression is maximum within the 2–6 m range. Furthermore, an analysis of the main factors contributing to fracture failures and structural deteriorations of these poles is conducted using the finite element extension method. It is determined that shallower crack depths and higher concrete strength enhance fracture resistance and the bearing capacity of concrete poles. Notably, annular cracks at the 2.4 m height are more prone to spreading.
