Abstract
Similar to conventional concrete, the use of supplementary cementitious materials (SCMs) in 3-D printing concrete (3DPC) can be technically and environmentally beneficial. 3DPC consumes larger amount of Portland cement compared to conventional concrete so replacing the cement with SCMs will reduce the carbon footprint of 3DPC. However, it is important that the level of replacement does not lead to a significance loss of the mechanical performance of 3DCP. Therefore, this study investigates the mechanical strengths of 3DPC with various mix compositions. Mixes containing fly ash, metakaolin, nanoclay, and combination of them were studied. The test program includes measuring the compressive strength and flexural strength on standard cubes/prisms as well as 3D printed cubes/prisms at 7 and 28 days. The findings showed that fly ash decreased the early age strengths but led to an increase in the late age strengths. On the other hand, metakaolin and nanoclay did not remarkedly affect the strengths. It was found that mixes containing both fly ash and metakaolin showed better performance. Finally, it was observed that samples from 3D printed concrete had lower strengths compared to the same mixes poured in standard cubes and prisms. Optimisation of the mix compositions using these SCMs is required to achieve acceptable mechanical performance.
