Investigation into the effect of full replacement with Portland slag cement and screened slag sand for development of sustainable 3D printed concrete

Key Points

• Enhanced sustainability is observed in 3D printed concrete mixtures with Portland slag cement and screened slag sand.
• Testing shows improved performance metrics in concrete mixtures comprising over 50% slag materials.
• Investigation employs analysis of various concrete mixtures incorporating sustainable materials to evaluate properties.
• These findings highlight the potential for sustainable practices in concrete production and construction.
