Abstract

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.

FA 和 HPMC 对三维打印工程水泥基复合材料（3DP-ECC）新鲜特性和各向异性的影响

为了研究材料成分对 3DP-ECC 的新鲜特性和各向异性的影响，研究了粉煤灰（FA）和羟丙基甲基纤维素（HPMC）不同含量的 3DP-ECC 的形状保持率和抗压强度的各向异性。研究结果表明，粉煤灰会削弱 3DP-ECC 的保形性，但 HPMC 能显著增强 3DP-ECC 新浆的保形性。随着添加量（FA/HPMC）的增加，添加 HPMC 的 3DP-ECC 抗压强度的各向同性减小，但添加 FA 的 3DP-ECC 的抗压强度差异逐渐明显。
