Abstract

The growing demand for cement production to support the rapid growth of the construction industry has resulted in a significant contribution to global carbon emissions due to the high energy requirements of cement production. Addressing this issue requires the development of eco-friendly cement modifiers/additives. Graphene, known for its exceptional properties, has emerged as a versatile material in various domains, including construction. Its incorporation into cement has exhibited promising prospects, surpassing geopolymer performance and enhancing cement quality. Nevertheless, challenges persist, such as inadequate dispersion in concrete mixtures and quality control issues during large-scale production. Harnessing the potential of graphene oxide can revolutionize cement performance and contribute to a more sustainable construction industry. Addressing dispersion challenges and ensuring successful large-scale production are pivotal steps towards realizing these benefits. This comprehensive review investigates the potential of graphene oxide in the construction sector, specifically focusing on its capacity to reinforce cementitious composites and highlighting the associated implementation challenges, paving the way for more sustainable cement production with a touch of scientific excellence.

Abstract

The prohibition of asbestos in ceiling board production, due to its serious health risks, has prompted the search for safer and more sustainable alternatives. Current solutions often rely on non-renewable synthetic fibers, which pose environmental concerns. This study investigates the potential of using two abundant tropical waste materials—Calotropis gigantea leaves and eggshells—as renewable reinforcements in biocomposite ceiling boards. In Indonesia, eggshell waste from households and the food service industry amounts to approximately 483,920 tons annually, while C. gigantea grows widely along the country's coastal areas. The biocomposites were formulated by combining leaf fiber powder and eggshell-derived calcium carbonate (32.63–33.92% CaCO₃) in a resin matrix at various ratios. The resulting panels were evaluated through density, water absorption, drop resistance, and gradual heating tests. All samples exceeded the national density standard (SNI 03-2105) and demonstrated superior water and thermal resistance compared to commercial gypsum and kalsiboard panels. No sample failed under impact or heating up to 200°C. The presence of CaCO₃ contributed to improved mechanical and thermal performance while supporting the substitution of cement-based materials. These findings demonstrate the feasibility of utilizing post-consumer and plant-based tropical waste in environmentally friendly construction materials, offering a promising pathway for sustainable resource use, waste reduction, and green building practices in tropical regions.
