The growing demand for sustainable construction practices, increasing environmental pollution and the rising impact of construction activities has led to the exploration of new technologies and sustainable materials. 3D printing in construction is rapidly emerging as an innovative alternative to conventional building practices, enabling faster, more precise, and cost-effective fabrication of complex structures. However, the high cement content traditionally used in printable concrete raises sustainability concerns due to its significant carbon footprint. To address this challenge, this project explores the development and application of sustainable concrete mixes for 3D printing by partially replacing cement and natural aggregates with supplementary cementitious materials such as fly ash, silica fume along with recycled aggregates and fibers like basalt, polypropylene fiber. The waste materials offer environmental benefits by reducing landfill waste and material demand, their successful integration requires optimizing concrete mix proportions and printing parameters to balance properties like early strength, flow, and overall structural integrity. By integrating green materials into 3D-printed concrete, the project aims to significantly reduce environmental impact, enhance resource efficiency, and promote the large-scale adoption of sustainable construction practices.
