“…In previous research, the second approach was mostly applied. For instance, in References 37 and 38, an RC column with chosen size dimensions was applied as FU. Silva et al 39 chose a linear member with a specified length and cross‐section size as FU and performed the service life prediction for different concrete mixes.…”

The environmental impacts of activities such as raw material extraction, construction of infrastructure, and demolition, place construction as one of the sectors that exert the highest pressures on the environment, society, and economy. Some of the major environmental impacts for which the construction industry is responsible are mineral resource depletion, greenhouse gas emissions, and waste generation. Among the different strategies that exist to decrease such impacts, recycling demolition waste into recycled concrete aggregates has been considered a promising alternative. As such, at present, the literature dealing with the impact assessment of recycled aggregate concrete structures is very extensive. Therefore, the objective of this article is to present a critical view of the state-of-the-art in terms of sustainability assessment of recycled aggregate concrete structures, taking a holistic perspective by considering environmental, social, and economic impacts.

“…Recently, the number of international studies related to LCA in the construction sector has increased enormously [8,9]. Some of them applied LCA for very diverse building materials and components, such as cement [10], bamboo [11], conventional building materials [12], wood products [13,14], other bio-based materials, earth materials [15], concrete [16][17][18], and recycled materials [19][20][21]. In terms of recycled materials, special attention is given to studying recycled aggregates, some of them using LCA and Life-Cycle Costs (LCC); for example, the Sustainable Aggregates Resource Management project (SARMa) [22].…”

In continental countries, building materials are often moved over long distances from factories to building sites. This is especially important when quality and performance certification systems are required for the building materials’ acquisition. In this scenario, the transportation phase tends to have a great contribution to building materials’ environmental impacts. Taking into consideration that countries such as China, India, and Brazil, i.e., continental countries, are expecting the largest future housing demand, the issue of transportation will have a crucial role in environmental impacts. Through a Brazilian case study, the present work investigates the potential environmental impacts of structural masonry made of concrete and ceramic blocks certified by the Brazilian Quality Program. A cradle-to-site Life-Cycle Assessment (LCA) is carried out while considering a country-level approach using data from the literature and Ecoinvent. The results show that ceramic blocks are preferable for most states and scenarios. Human Health and Ecosystem Quality are the two categories most affected by transportation, and they can reach more than 96% and 99%, respectively. The efficiency of the building material transportation system plays an important role in reducing greenhouse gas emissions. A shift in building components from concrete to ceramic blocks has the potential to mitigate between 154 and 229 Mt CO2-eq between 2020 and 2050. The methodological approach used in this work can be applied to other building materials and other countries, especially those of continental dimensions that are expected to have a significant future housing demand.

“…From the point of view of the functional comparing of structures by the LCA method, two main principles have been defined [ 30 ]. In Principle I, which is primarily applied, the FU is related to mechanical properties, the volume of the structural element is constant, and the service life of the structural element varies according to the durability of the material [ 31 , 32 , 33 ]. In Principle II, the FU depends on mechanical properties, the service life of the structural elements stays constant, and the volume of the structural element varies according to the durability of the material such as freeze–thaw, carbonation, and chloride resistance.…”

In the case of concrete sustainability, two main ways are generally discussed: (1) the reduction of natural raw materials and (2) the reduction of emissions related to concrete production. Following the second point, there have not yet been reported clear results. This problem is not given enough attention in present publications. This study brings a general view of this issue and a basic comparison with common concrete and traditional reinforcement. This case study deals with the life cycle analysis of a concrete slab made of recycled aggregate concrete with a fine recycled aggregate. The concrete slab was designed according to the limit states of load-bearing capacity and serviceability, which is based on the experimental verification of recycled aggregate concrete properties. Two different reinforcements are compared: (1) ordinary reinforcement by steel bars and (2) glass fibers. Furthermore, scenarios vary due to the slab thickness and reinforcement percentage. The results show the positive environmental impact of replacing natural sand with a fine recycled aggregate. The reduction of climate change potential can be almost 40% in some cases.
