Influence of FA and HPMC on the fresh properties and anisotropy of 3D printing engineered cementitious composites (3DP-ECC)
To investigate the effect of material compositions on the fresh properties and anisotropy of 3DP-ECC, the shape retention and the anisotropy of the compressive strength of 3DP-ECC with different contents of fly ash (FA) and Hydroxypropyl methyl cellulose (HPMC) were studied. The research results indicated that FA could weaken the shape retention, but HPMC significantly enhanced the shape retention of the fresh slurry of 3DP-ECC. The compressive strength in different directions was ranked as Z > Y > X. With the increase of dosage (FA/HPMC), the isotropy in the compressive strength of 3DP-ECC with HPMC decreased, but the difference of 3DP-ECC with FA became more obvious gradually.
