Special Issue Information

Dear Colleagues,

Sustainable engineering, civil, mechanical, environmental, etc., under the actual conditions of rapid population growth, urbanization, and climate change, requires the application of sustainable materials to achieve environmental, social and financial paradigms of sustainability and presenting the possibility of saving the natural resources for future generations. Thus, there is a constant need to design, research, evaluate, and apply new, up-to-date, and sustainable materials supporting the sustainable development of urbanized and rural societies.

This Special Issue of Sustainability “Evaluation and Application of Sustainable Engineering Materials” will publish original research, which adds knowledge to the current understanding of sustainable engineering materials and their ability to limit anthropo-pressure on the natural environment, utilize the recycled substrates, as well as renewable energy sources, reduce investment and operational costs of construction and, finally, meet the social acceptance and involvement.

The scope of Special Issue includes original articles, case studies, and critical review papers presenting the following topics:

  • New trends in the design of sustainable engineering materials;
  • Substrates and compositions of sustainable engineering materials;
  • Application of local and recycled materials to sustainable engineering;
  • Strength, durability, hydraulic, characteristics of sustainable materials;
  • Studies on engineering applications of sustainable materials under variable local conditions;
  • Evaluation of innovative engineering materials meeting environmental, technical, legal, economic, and social principles of sustainable development.

This Special Issue of Sustainability will report up-to-date information considering all aspects of engineering materials sustainability and allow the transfer of actual knowledge and good engineering practice to scientists and engineers interested in the development, testing, and applications of sustainable engineering materials.

It is my pleasure to invite you to submit a manuscript to this Special Issue.

Leakage of hydraulic oils causes long-term damage to the environment. Every year, a significant amount of hydraulic oil is released into the environment through accidents and leakages. Biohydraulic oils minimize the risk of environmental damage due to their biodegradability and lack of toxicity. Mobile machines offer great substitution potential for biohydraulic oils. The majority of machines are operated with mineral hydraulic oils. Furthermore, in view of decreasing energy resources and rising CO2 emissions, there is a strong interest in reducing the fuel consumption of mobile machines. Triggered by this trend, the power density of hydraulic systems and their components continue to increase. Resulting, the used hydraulic fluid is subject to greater thermal stress and the system thermal of the used fluids are becoming increasingly important. Biohydraulic oils offer a great potential due to their thermal properties, regarding viscosity temperature dependency. Therefore, the content of this article is to consider the influence of hydraulic oil’s viscosity on the efficiency of a crawler excavator. For this purpose, experimental tests are discussed by regarding viscosity related energy losses of hydraulic systems of crawler excavators by using biohydraulic oil. A hypothesis about the dependency of rheological properties of biohydraulic oils on the hydraulic system’s efficiency is formulated. Full article

This paper presents research considering hydraulic as well as swelling and shrinkage characteristics of potential recycled fine particle materials for compacted clay liner for sustainable landfills. Five locally available clay soils mixed with 10% (by mass) of NaP1 recycled zeolite were tested. The performed analysis was based on determined plasticity, cation exchange capacity, coefficient of saturated hydraulic conductivity after compaction, several shrinkage and swelling characteristics as well as, finally, saturated hydraulic conductivity after three cycles of drying and rewetting of tested specimens and the reference samples. The obtained results showed that addition of zeolite to clay soils allowed reduction in their saturated hydraulic conductivity to meet the required threshold (≤1 × 10−9 m/s) of sealing capabilities for compacted clay liner. On the other hand, an increase in plasticity, swelling, and in several cases in shrinkage, of the clay–zeolite mixture was observed. Finally, none of the tested mixtures was able to sustain its sealing capabilities after three cycles of drying and rewetting. Thus, the studied clayey soils mixed with sustainable recycled zeolite were assessed as promising materials for compacted liner construction. However, the liner should be operated carefully to avoid extensive dissication and cracking. Full article

The application of recycled coarse aggregates (RCA) in high-performance concrete (HPC) was analyzed in the article. In the paper, the behavior of HPC with coarse recycled aggregate and natural coarse aggregate (NCA) was compared. Short-term experiments were conducted, including concrete deformation, deflection, load bearing capacity, and cracking of beams. The analysis involved reinforced concrete T-beams made in 100% of RCA or NCA. The studies indicated that the beams with recycled aggregate are characterized by greater deflection and 7.6% lower load bearing capacity in comparison to the beams with NCA. Substitution of coarse natural aggregate with RCA reduced the compressive and tensile strengths by 20 and 26 (%), whereas and the modulus of elasticity was decreased by 15%. Full article

The research concerned the mortars with recycled stone aggregate used for the reconstruction of historic objects. The face of stone walls is exposed to atmospheric, chemical, and biological factors, causing its destruction. The aim of the research was to develop a mortar that would be compatible with the stone both in terms of its external appearance as well as its physical and mechanical properties. For this purpose, three mortars based on recycled sandstone aggregate with three different gradations were prepared. The compatibility of stone and mortar was tested in terms of the physical and mechanical properties as well as the resistance to salt and frost corrosion. The mortars reflect the properties of sandstone and offer great opportunities to adjust them as desired. The frost resistance of the mortars was consistent, with practically no weight loss after 25 test cycles. They achieved lower compression strength than stone, which is an important feature in avoiding destruction by using an excessively strong mortar. Moreover, the absorbability of the mortars turned out to be favorable (max. 25%). Mortars were resistant to the destructive effect of salt and did not show the ability to whitewash and desalinate.
