Special Issue Information

Dear Colleagues,

With the ever-increasing world population, the need for robust infrastructure and housing developments is putting pressure on governments and people alike. From a sustainability perspective and to accommodate future populations, it is essential to continuously look for ways to use primary resources in building materials more efficiently.

Developing sustainable materials and construction processes are at the heart of previous, current, and future research and never ceases to age.

The construction industry and related infrastructure are critical indicators to measure the success and development of countries.

As a material, concrete is the composite that has been and is still used as a primary building material, with a market projected to bring in more than 620 billion USD in profits in less than three years from now. Concrete is second to water as the most used substance in construction. Other building materials include steel and wood. One of the key advantages of using concrete as a construction material is recycling it for reuse in other civil engineering projects, thus reducing the exploitation of natural resources and associated costs.

With the growing concern about environmental issues and the energy crisis, sustainable development in the construction industry has become a global concern. The concept of sustainable building and development covers the entire life cycle of the buildings. It is intended to minimize all adverse impacts on the natural and built environments through environmentally friendly building designs and materials. Accordingly, research on developing sustainable materials and design methods is essential.

This Special Issue aims to disseminate research on sustainable materials and structural engineering that directly benefit the built environment and efficiently exploit natural resources.

In this Special Issue, original research articles and reviews are welcome. Research topics may include, but are not limited to, the following:

Efficient use of building materials

Composite materials and their contribution to reducing environmental impact.

Energy-efficient buildings

Structural engineering for improved sustainability.

Structural retrofitting and rehabilitation for durable and sustainable infrastructure.

New building materials and construction processes

Life cycle analysis of sustainable technologies

Material recycling and recovery

We look forward to receiving your contributions.

This paper describes the process used to produce thermoplastic building materials from non-recyclable mixed plastic–paper packaging waste. A first step was dedicated to an innovative and sustainable sterilization technology for non-recyclable waste, based on exposure to microwave radiation in closed air-circulation ovens. Further, composites with different cellulose contents and with two polymer matrices, respectively, were obtained using an injection process, and the samples were subjected to mechanical and physical tests. Due to their superior features, the products based on mixed polypropylene–paper packaging waste may successfully replace the classic polyvinylchloride-based wood–plastic composites. The environmental impact of mixed plastic–paper packaging waste was analyzed, and the sustainability of the thermoplastic technology was demonstrated from an economic and environmental point of view.

Nowadays, fiber-reinforced polymer (FRP) has become a widely accepted alternative reinforcement to steel bars in concrete members due to its many sustainability traits, as represented by its high strength-to-weight ratio, corrosion resistance, non-conductive properties, and electromagnet neutrality. However, FRP bar exposure for an extended period of time to harsh environmental conditions and chemicals can have an adverse effect on their mechanical properties. In this investigation, glass FRP bars were exposed to indoor controlled temperature, outdoor direct sunlight, outdoor shade, seawater, and alkaline solution for six months prior to using them as reinforcement in concrete flexural members. This research involves the fabrication and testing of five pairs of 3 m-long concrete beams with 200 mm by 300 mm cross-sections embedded in the tension zone with the exposed GFRP bars. The 10 beams were instrumented with strain gauges and tested following a four-point loading scheme using a hydraulic jack attached to a rigid steel frame. Crack width records from the tests showed the inferior serviceability of the beams that contained rebars stored in an outdoor environment relative to the control beams. GFRP bar exposure to an alkaline solution or outdoor direct sunlight slightly affected the cracking and ultimate moment capacities, reducing them by 5% and 3% in terms of the same parameters as the controlled indoor exposure, respectively. The influence of GFRP bar exposure to open-air shade or sunlight decreased the pre-cracking stiffness by 25% and flexural ductility by 10–20% when compared with the control specimens. The predicted ultimate flexural strength using the ACI 440 provisions gave comparable results to the experimentally obtained values. A simple mathematical equation that envelops the moment–deflection relationship for GFRP over-reinforced concrete beams and only requires information about initial cracking and ultimate flexural conditions is proposed.

Radiation-shielding glass is utilized in a few applications such as nuclear medicine, (PET) scans, x-rays, or treatment use. Nuclear reactors additionally require shielding from radiation types such as gamma, x-rays, and neutron emissions. Radiation-shielding glass is additionally utilized in the exploration and industry fields, for example, in cyclotron support testing of non-destructive materials, and the improvement of airport x-ray machines. Notwithstanding, radiation-shielding glass utilizes space innovation to protect both the astronauts and tools from cosmic rays. Nanoparticles have been involved recently in those applications. Several simulations using MCNP 6 have been used in this study to compare a variety of conventional and nanoparticle-doped glass, including silicate glass (containing BiO or PbO), BZBB5, and glass containing nanoparticles, including Na2Si3O7/Ag, Al2H2Na2O13Si4/HgO, and lead borate glass containing ZrO2 to detect shielding properties for operators at different gamma energies. We investigated the percentage of transmitted photons, linear attenuation coefficient, half-value layer, and mean free path for the selected glass. Several shielding properties were not significantly different between the simulated results and the theoretical data available commercially. Based on the results, those parameters depend on the glass material due to their densities and atomic number. It has been found that 70 Bismuth(III) oxide:30 Silica has the best shield properties from gamma rays, such as a low percentage of transmitted photons, low HVL, and low MFP, which is due to its high density and atomic number.

In this study, based on the actual project in Dalian, the dynamic interaction of the double tunnel sand bridge pile system (SSSI) under earthquake action is studied by shaking table test, and the dynamic response laws of the structure and site are obtained, which are compared with ABAQUS numerical simulation. The Kelvin constitutive model subprogram is introduced into the numerical model, and the equivalent linear method is used to deal with the nonlinear problems of sand in the calculation process. The experimental results are compared with the results obtained using the numerical model to verify the reliability of the numerical simulation. Based on this, eight working conditions are designed, and the interaction law between the structures in the system is investigated through a comparative analysis. The results showed that the tunnel amplifies the dynamic responses of the bridge pile, adjacent tunnel, and far field, while the bridge pile attenuates the dynamic responses of the side tunnel and far field; the presence of both the tunnel and bridge pile increases the internal force of the adjacent structure, and the peak internal force often occurs near the intersection of the structure or at the pile–soil interface.
