“…RCA has a crucial role to play in achieving the recycle-closed-loop strategy in C&D waste management and the ability to achieve a greener environment [21]. In this regard, economic benefits were addressed by Kumar et al [36], who used and analyzed a cost-benefit model of RAC production and focused on the economic effects. This study found that GC materials produced from RA that are used in industrial-scale manufacturing have low prices.…”

Increasing the rate of construction material consumption has caused significant environmental problems in recent decades, especially the production of ordinary Portland cement (OPC), which has been associated with 8% of the world’s human CO2 emissions and is considered the leading binder of concrete. This study aims to investigate the effects of substituting conventional concrete (CC) material with green concrete (GC) in the non-structural concrete works of a residential building in New Borg El-Arab City, Egypt. It attempts to establish what the effects are of using GC on cement, natural aggregates, and CO2 emissions in the design phase. By using a design-based solution (DBS), we began with redesign, reduce, reselect, reuse, and recycle strategies to find an optimal solution for applying recycle aggregate concrete (RAC) as a replacement material in selected building parts, such as the internal floor, external sidewalk, entrance steps, and wall boundary. AutoCAD software and 3Dmax were used to modify the original design and obtain two design references with four different scenarios. Comparative analyses were applied to investigate the effects of different concrete materials. The results show a reduction of about 19.4% in cement consumption in terms of the total concrete of the building and a 44.5% reduction in CO2 emissions due to the reduction of cement in specific building parts. In addition, this solution decreased natural coarse aggregate (NCA) consumption by 23.7% in the final concrete. This study recommends that GC materials close the loop of cementitious material consumption to reduce environmental impacts and achieve sustainability in the Egyptian building sector.

“…By selecting materials with lower embodied energy, minimal waste generation, and recyclability, construction projects can significantly reduce their environmental impact and contribute to preserving natural resources and ecosystems. 11,[22][23][24][25][26][27][28][29][30] By taking a comprehensive approach to evaluating sustainable construction materials, decision-makers and practitioners can ensure that their choices align with environmental and financial sustainability and foster social well-being and equity. This integrated perspective will enable the construction industry to uphold its commitment to sustainable development goals and pave the way for a more responsible and resilient built environment.…”

This paper aims to review the literature on ‘Sustainable Construction Materials (SCMs)’ based on the Scopus database and synthesise the review. Three advantages of embracing ESG in sustainable construction materials are identified based on the literature reviewed. Firstly, this can significantly reduce the environmental impact of buildings and contribute to achieving the United Nations’ Sustainable Development Goals (UNSDGs). Secondly, by taking a comprehensive approach, decision-makers and practitioners can ensure that their choices align with environmental and financial sustainability and foster social well-being and equity. Thirdly, this can create healthier and more energy-efficient built environments for future generations. Fourthly, this will enable construction practitioners to make informed decisions that consider the holistic impacts of SCMs throughout their life cycle and promote greater transparency and accountability in their selection and use. On the challenge side, the triple bottom line of sustainability encompassing social, economic, and environmental aspects should be rigorously evaluated when considering sustainable construction materials. This integrated perspective is crucial for upholding the construction industry's commitment to UNSDGs and promoting a more responsible and green environment. Decision-makers and practitioners must prioritize implementing SCMs to positively impact the environment, society, and economy.

“…Incorporating seashells into concrete mixtures can have several positive environmental and sustainable benefits, (i) reduced cement demand can directly lower the carbon footprint of concrete production; (ii) enhanced durability and strength; (iii) improving insulation; and (iv) aesthetic appeal [4].…”

“…This includes the use of alternative cementitious materials, waste by products, and innovative manufacturing techniques [5]. Among the alternative materials, fly ash, seashell, slag, silica fume, geopolymer and nano materials have been commonly employed as partial cement replacements in concrete and mortar due to their pozzolanic properties [4,[6][7][8][9][10][11][12]. However, the quest for more sustainable alternatives has led researchers to investigate unconventional materials, such as seashell powder.…”

Creating sustainable mortar containing recycled seashells is an innovative approach that can contribute to environmental conservation and reduce waste. The use of seashells as a partial replacement for traditional raw materials in mortar can have several benefits, including conservation of natural resources, waste reduction, and improved material properties. The current study uses Marsh Clam seashells after crushing the cleaned seashells into powder. Heated ( up to 600Co) and unheated seashells were considered in the experimental investigation. In both batches, a seashell powder (heated and unheated) was replaced with OPC cement in proportions of 6, 9 and 12% in the mixing process. XRD, SEM, EDS and mechanical tests were employed to determine the crystal structure and to provide a comprehensive understanding of the physical, chemical, and structural characteristics of the substance. The study concluded that the calcium carbonate (CaCO3) that is nature chemical form of seashells was turned to calcium oxide (CaO) during the heating process and the resulted product was highly reactive with water, improved microstructural properties of the concrete. It also promotes better particle packing, reduce porosity, and create a denser, more uniform concrete matrix and enhancing the overall performance of the material.
