Concrete for 3D printing and preparation method thereof
The invention relates to the technical field of building materials, and particularly discloses concrete for 3D printing and a preparation method thereof. The concrete for 3D printing is prepared from the following raw materials in parts by weight: 36-96 parts of Portland cement, 60-120 parts of gravel, 1-8 parts of silica fume, 1-6 parts of fly ash, 1-5 parts of a water reducing agent, 16-32 parts of water and 4-10 parts of a quick-setting material, the quick-setting material comprises a quick-setting body and a dispersion body coating the quick-setting body, wherein the quick-setting body comprises triethanolamine; the preparation method comprises the following steps: S1, primary mixing; S2, secondary mixing; and S3, blending. The concrete for 3D printing has the advantage that the rapid hardening effect is improved.
本申请涉及建筑材料的技术领域，具体公开了一种用于3D打印的混凝土及其制备方法。一种用于3D打印的混凝土，由包含以下重量份的原料制成：硅酸盐水泥36‑96份、砂石60‑120份、硅灰1‑8份、粉煤灰1‑6份、减水剂1‑5份、水16‑32份、速凝材料4‑10份；所述速凝材料包括速凝体和包覆于速凝体外的分散体，所述速凝体包括三乙醇胺；其制备方法为：S1、一次混合；S2、二次混合；S3、共混。本申请的用于3D打印的混凝土具有提高速凝效果的优点。
