The influence of fine aggregates on the 3D printing performance
Influences of nature Particle,size,grain shape and fineness modulus of fine aggregates on the 3D printing performance of cement-based mortar were investigated.Results showed that the working performance of the mortar is not only dependent on the fineness of the aggregate,but also the gradation and grain size of the aggregate.And the mechanical properties of the mortar are increasing with the increase of Mx in the same test condition.The research shows that it is effective to choose different properties of materials for different design requirements,and the fluidity of mortar must be decreased under assuring construction quality and the pumpability of 3D printing materials.
