Abstract Tungsten tailing powder (TTP) was used as a supplementary cementing material to partially replace cement in 3D printing low carbon concrete. The influence of TTP on the rheological properties and hydration heat of blended cement paste was investigated. Meanwhile, 3D printing low carbon concrete with varying TTP content were successfully prepared by adjusting the dosage of additives to optimize their printability. The results show that the addition of TTP reduces the initial static yield stress, dynamic yield stress, and plastic viscosity of the blended cement paste due to particle accumulation and the reduction of total specific surface area of the system. According to the hydration heat results, the addition of TTP reduces the hydration heat release of blended cement in the first 2 h due to the dilution effect, reducing the growth rate of static yield stress with time. The compressive strength decreases as the TTP content increases, and the compressive strength of 3D printed specimen is slightly lower than that of cast specimen. 3D printed concrete specimen with 28d compressive strength ranging from 30 MPa to 60 MPa can be prepared when the replacement ratio of TTP is less than 45%. The appropriate TTP dosage can be determined based on the various demands in different engineering applications. Overall, TTP has the potential to be used as raw material for preparing 3D printable low carbon concrete.
