| description | 3D printing of cementitious material/concrete is getting more and more attention
from both industry and academic in recent years. Unlike traditional construction, fresh
cementitious material pumpability and buildability is crucial in 3D printing process. Only with
appropriate pumpability and buildability, cementitious material can be transported in the delivery
system smoothly then be deposited layer by layer firmly. The pumpability and buildability have
closely relationship with fresh rheological properties of the cementitious material. In this paper,
the fresh rheological properties of three kinds of materials were measure via the large gap
viscometer. Two different models (Bingham model, modified Bingham model) were applied to
derive the yield stress and plastic viscosity of each cementitious material. Experimental results
show that the predicted yield stress and plastic viscosity varies a lot even for the same material and
the deviation of plastic viscosity is much larger than that of the yield stress. |
