Abstract:

Concrete is a crucial construction material due to its global consumption and environmental impact. Sustainable concrete construction trends and opportunities are essential due to global warming and environmental changes. Green concrete, additional cementitious materials, permeable concrete, cool concrete, and local materials are examples of sustainable materials and technologies. Self-healing concrete, geopolymer concrete, 3D-printed concrete, photocatalytic concrete, electrified equipment, and carbon capture, usage, and storage technologies are discussed as potential improvements to construction sustainability. Impacts on sustainable concrete construction are addressed from technical, economic, and sociological standpoints. Governments, businesses, and academia must work together to promote sustainable concrete construction through interdisciplinary collaboration and research. Digitation, data-driven methodologies, and circular economy principles are critical to the development of sustainable concrete structures. A questionnaire was sent to construction experts (academics, contractors, and engineers) to measure the importance of actual sustainability standards. A comprehensive literature analysis revealed 41 concrete sustainability variables, classified into three groups: Economic, Environmental, and social factors. Factor Analysis method was used to identify key factors among these variables. The Fuzzy Analytic Hierarchy Process (FAHP) was used to prioritize the weights for selected variables and establish a relationship between them. The sustainability of a concrete structure is typically assessed using various criteria and metrics, but there is no single sustainability index for concrete structures.
