In recent years, additive manufacturing (AM) technology has been one of the emerging innovations in the construction industry and has significant advantages over traditional casting methods. Current scenario mainly faces some challenges upon the material composition of printable materials. Earlier studies reveal a significant lack of experimental data and validated models on additive manufacturing materials. Researches should focus on developing materials with good rheological characteristics to guarantee acceptable fresh and hardened properties. This review paper provides insight into the properties of various printable mixtures and gives proper direction to developing a systematic procedure for mixture design by assessing their extrudability, buildability, robustness and workability retention along with their hardened properties
