Although pulverized concrete does not compromise compressive strength, its weak adhesion to cement may restrict the plastic content [14].…”

“…In 2021, more than 100 million tons of cement were manufactured in the United States for the production of concrete, and consequently, the cement industry contributes to the emission of greenhouse gases in the millions of tons, representing a sizable portion of the carbon footprint of the nation [14]. Concrete optimization has been proven to not only affect cost efficiency, but also make a real contribution to sustainability.…”

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.

“…Mineral additives like FA and slag powder are widely used for reducing cement content, reducing the heat of hydration and enhancing the mechanical properties and durability of mass concrete. However, the supply of high-quality mineral additives is limited, so it is important to realize the sustainable development of mass concrete to seek suitable alternative materials and reduce the amount of cement [1]. As a by-product of the production of manufactured sand, LP has a wide range of raw material sources and features, including filling effects, diluting effects and nucleating effects [2][3][4][5], which can not only optimize the properties of concrete, but also lower the adiabatic temperature rise of concrete.…”

Using limestone powder (LP), the by-product of manufactured sand, to replace part of fly ash (FA) or manufactured sand could not only turn waste into treasure and decrease the price of concrete, but could also enhance the performance of concrete and reduce environmental pollution. However, the impact of various LP incorporation methods on the performance of mass concrete was inconsistent. In this paper, the effects of LP on the workability, compressive strength, constrained expansion rate, hydration temperature and impermeability of mass concrete were studied by replacing FA or manufactured sand alone and replacing FA and manufactured sand simultaneously. The results showed that the impact of LP on the performance of mass concrete was equal when it replaced FA alone and FA and manufactured sand at the same time. When the replacement amount was 20%, the workability, expansibility and early strength of concrete were improved, but the later strength and impermeability were slightly reduced. The workability, compressive strength, expansibility and impermeability of mass concrete were improved when manufactured sand was replaced alone, and the optimal dosage was 10%. The LP, moreover, reduced the hydration temperature peak of concrete in three kinds of mixing methods, but the temperature peak appeared earlier. At lower dosages, LP optimized pore structure and promoted the early hydration of cement through filler effects and nucleation effects. When LP replaced manufactured sand, the microstructure of concrete was more dense, so the replacement of manufactured sand had a better effect on the improvement of concrete properties. A reference value for the use of LP in mass concrete is provided in this study.

As plastics become more ubiquitous, their impact on the environment and on human health cannot be overlooked. Once generated, micro‐ and nano‐plastics end‐up in the environment, causing widespread health and environmental risks. This is a significant environmental problem given the minuscule sizes of microplastics, and therefore warrants further investigation. This study presents a comprehensive review of the ecotoxicology of microplastics and methods for their degradation and decomposition besides discussing the fate and transport processes, recent progress, emerging strategies, challenges and potential future directions. The authors carefully evaluate the processes through which microplastics cause harm, from molecular interactions in species, to ecological impacts, and end with advances in microplastic biodegradation. Different kinds of microplastics found in the environment include polyethylene, polystyrene, polypropylene, polyvinyl chloride, polycarbonate, polyurethane, polypropylene, and polyethylene terephthalate. Analysis of microbial and enzymatic decomposition provides several swelling mitigation strategies designed to reduce environmental threats. In‐depth investigations of microplastic ecotoxicity and biodegradation are being facilitated by interdisciplinary proposals in the areas of nanotechnology, new analytical methods, and synthetic biology. The extensive study helps understand microplastics comprehensively which in‐turn ensures informed actions to mitigate the challenge of the environmental impact of microplastics for sustainable future.
