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.

“…When the specified concrete strength is 50 MPa., the maximum ECM proportion represents the optimal ratio. The density, cost, and carbon emission factor of each component are consolidated in Table . , To achieve an optimal mix ratio, it is crucial to establish appropriate values for the water:cement ratio, sand ratio, superplasticizer content, and stone powder content. The limiting conditions are provided in Table .…”

Marble powder (MP) and granite powder (GP) are disposed of primarily through landfilling, which leads to severe environmental issues. The utilization of stone powder in cement-based materials offers a scalable disposal method. This paper begins by presenting the two powders’ basic physicochemical and micromorphological characteristics. Then the effects and mechanisms of MP and GP on the hydration process and microstructure of the concrete are examined. Moreover, the influences of different substitution methods, water-cement ratio, and other factors on the macro properties of concrete incorporating stone powder are comprehensively summarized, bridging the gap between the microscopic changes induced by the addition of stone powder and the macroscopic differences observed in experiments. The current state of relevant technical standards is analyzed. Leveraging previous research results, we used machine learning techniques to optimize the mixture ratio of stone powder concrete with the aim of achieving a comprehensive life cycle performance index. The results reveal that by fully exploiting the fineness and composition characteristics of MP and GP, along with employing a suitable mix design, stone powders exhibit filling and nucleation effects that accelerate cement hydration, refine the pore structure, and enhance the workability, mechanical properties, and durability of concrete. Following the proposed optimization of the concrete mixture ratio, substituting 16% of cement can maintain the standard strength of 50 MPa while reducing the carbon footprint by 108.8 kg CO2e/m3 as well as saving the cost of 284.8 yuan/m3. This Review is expected to promote further applications of waste stone powder in cement-based materials to achieve sustainable development.
