Special Issue Information

Dear Colleagues,

Older buildings consume an excessive amount of energy and produce too much waste. Their operation is also linked with the consumption of about 25% of the world’s water and 40% of its resources, while creating one-third of all waste and 40% of global carbon emissions. Despite these statistics related to buildings’ unsustainability, buildings have a huge untapped potential to become a key part of the solution to urgent sustainability challenges. One of the important ways to improve the sustainability of buildings is to produce environmentally friendly materials and to design new eco-friendly building constructions. New eco-friendly designs of buildings based on the construction of environmentally friendly materials can improve human health, safety, comfort, and productivity in the current conditions of climate change. Environmentally friendly materials must become part of a sustainable world building design because their production and use could minimize the negative environmental impacts. These impacts are represented by climate change, ozone-layer depletion, acidification of soil and water, resource exhaustion, and human toxicity in connection to indoor and outdoor air pollution. Therefore, it is very important to include sustainability ideas into products, operations, and research and development in order to apply the best available technologies and produce materials/products that leave a smaller negative environmental footprint in the process. Life-cycle analysis (LCA) offers a useful and widely accepted methodology for the assessment of the ecofriendly sustainability and environmental performance of buildings. We invite you to submit high-quality research or review papers to this Special Issue, with an emphasis on new environmentally friendly building materials (concrete, mortars, plasters, bricks, insulating, and hybrid materials) and technologies. Some areas of interest for this Special Issue include but are not limited to the environmental benefits of composites incorporating alternative substances and fiber-reinforced biocomposites.

This Special Issue is the continuation of a very successful previous Special Issue with the same focus. Papers aimed at environmentally acceptable composition of materials in construction, designing environmentally friendly construction buildings and the environmental assessment of building materials, constructions, and buildings will be welcome. Papers will be accepted for this Special Issue after going through a rigorous peer-review procedure.

Growing environmental awareness has prompted a resurgence in traditional building techniques that rely on natural or recycled materials since many believe that structures made from these resources are ecologically friendly. Using Life Cycle Assessment (LCA) for construction materials offers valuable insights into the impacts produced during their production and construction processes. This study aims to assess the environmental impacts of two different constructions—an Earthbag Building (EB) and a conventional Sahrawi Cement Blocks Building (CBB). It also determines whether it is more environmentally beneficial to construct traditionally, utilizing local materials and aligning with the principles of the circular economy, which is one of the Sustainable Development Goals (SDGs) in Europe. This study specifically examines a cradle-to-gate LCA, using the software Simapro v. 9.4.0.1. Results show that in 21 out of the 22 impact categories analyzed, the CBB performs worse, in some cases presenting an impact of 70% higher than the EB. The highest impact is obtained for fine particulate matter formation and Global Warming related to Human Health categories, whilst impact categories related to water consumption and eutrophication obtained an impact of less than 0.001 for both constructions.

The surface hydrophilization of mixed plastic waste aggregates (MPAs) was conducted to improve the bond between an MPA and the surrounding cement matrix using two types of coating agents: a silicone amine resin and acrylic binders. The coating agents formed a physical bond with the MPAs, and the results of contact angle measurement also revealed that the surface of MPAs was hydrophilic. The workability of a mortar mix increased by up to 1.47 times with the surface hydrophilization of MPAs. Meanwhile, the compressive and flexural strengths of mortar mixes decreased by 29~43% and 72~86%, respectively, at 28 days with the surface hydrophilization of MPAs. Namely, the surface hydrophilization of MPAs was successively conducted, and the workability of mortar mixes was improved accordingly, but the compressive and flexural strengths of mortar mixes decreased as the physical bond was partially separated from not only the MPA but also the surrounding cement matrix and the surface friction was decreased.
