“…For example, by optimizing using green lightweight concrete in an integrated manner, an efficient structure can be produced and the need for concrete and reinforcing steel can be reduced. Thus, apart from cost efficiency, the effect on environment (emissions) and construction waste can be minimized [48].…”

“…Optimization of structural design has a greater effect when combined with the utilization of eco-friendly materials. In addition to optimizing the structural design, a study in Saudi Arabia compared the use of conventional concrete, recycled plastic aggregate concrete, and lightweight concrete, the framework considers possibilities which include safety of design, architectural specification, material's efficacy, cost-efficiency, and ecological consequence [48]. The present study assesses four distinct concrete aggregate materials, specifically natural weight aggregate, lightweight volcanic aggregate, and plastic-based green lightweight aggregates.…”

Delays in construction are a widespread global problem, leading to potential cost overruns and legal disputes. Additionally, delays can result in a decline in construction quality and loss of public trust. The aim of this study is to examine the effects of project delays in various regions and the preventive role of optimizing concrete works. Literature review and bibliometric analysis are carried out to determine global research trends. Findings show that optimizing concrete works can provide benefits such as cost savings, time savings, improved quality and safety, and environmental benefits. Optimization of concrete material composition is one of the most examined topics in this field. Based on the findings, construction firms have the potential to attain cost efficiencies while concurrently mitigating carbon emissions.

“…With the development of buildings towards higher, deeper, and larger volumes, higher performance is put forward for concrete materials, such as compressive strength, tensile strength, fatigue characteristics, and elastic modulus [3]. In addition, with the deterioration of the ecological environment, researchers are making efforts to build sustainability [4][5][6], such as using green building materials, low-carbon engineering designs, and efficient construction technology.…”

The evaluation of the elastic modulus of recycled concrete is one of the focuses of civil engineering and structural engineering, which is not only related to the stability of building structures but also related to the resource utilization of concrete. Therefore, based on the IRSM method in mesoscale, a novel model for predicting the elastic modulus of recycled concrete is proposed which has the advantages of being low-cost and high-precision, amongst others, compared to theoretical and experimental methods. Then, the influence of coarse aggregate, contact surface, gelling material, and air bubbles on the elastic modulus of recycled concrete is studied. The IRSM model includes four processes: Identification, Reconstruction, Simulation, and Monte Carlo, which can accurately reconstruct the geometric characteristics of coarse aggregate, efficiently reconstruct the coarse aggregate accumulation model, and quickly analyze the elastic modulus of concrete, as well as fully consider the nonuniform characteristics of coarse aggregate distribution and shape. Compared with the experimental results, the error is less than 5%, which verifies the rationality of the IRSM method. The results of the parametric analysis show that the influence of each factor on the elastic modulus of concrete in descending order is elastic modulus of cement, elastic modulus of coarse aggregate, content of coarse aggregate, content of air voids, elastic modulus of contacting surface, and thickness of contacting surface, and the corresponding Pearson’s Coefficients are 0.688, 0.427, 0.412, −0.269, 0.188, and −0.061, respectively, in which the content of air voids and thickness of contact surface have a negative effect on the elastic modulus of concrete. These influences mainly affect the deformation resistance (elastic modulus) of concrete through “force chain” adjustment, including the force transfer effect, number of paths, and integrity.
