Abstract

To meet the current expeditious work pace, innovative modus like 3D concrete printing will be useful in bridging sustainability in material usage with cost and time efficiency along with overcoming labor constraints. This preliminary study was aimed at partial replacement of 53 grade Ordinary Portland Cement (OPC) with Flyash (FA), Silica Fume (SF) and Ground Granulated Blast Furnace Slag (GGBS) in the preparation of mixes. The replacement percentages were decided based on literature review and preliminary trials. The fine aggregate of particle size in the range 1.18–2.36 mmwas used as fillers. The required workability for printing (based on trials) was achieved by using minimal dosages of a PCE based superplasticizer. The extrudability of mixes was tested with a simple mortar grouting applicator. The addition of 0.1% percentage of Polyvinyl Alcohol (PVA) fibre resulted in a better finish of the printed layer. The study is focused on the fresh and hardened state properties of printable cementitious mixes. The test results indicate that the mix containing GGBS, FA and fibre had better printability, good interlayer bonding, reduced gap time, and increased flexural and compressive strengths.
