Clay-based 3D printing special mortar and preparation method thereof
The invention provides clay-based 3D printing special mortar which comprises the following components in parts by weight: 30-40 parts of clay; 32 to 50 parts of sand; 0.12 to 0.15 part of PP (Propene Polymer) fiber; 4-6 parts of sodium silicate alkali residue; 3-5 parts of calcium oxide; 1.5 to 2 parts of fly ash; 11 to 15 parts of water; and 0.02 to 0.03 part of a water reducing agent. The invention discloses a preparation method of clay-based 3D printing special mortar. The preparation method comprises the following steps: S1, premixing clay, sand, fly ash and calcium oxide; s2, adding water and sodium silicate alkaline residues, and stirring; and S3, continuing to add the PP fibers, and stirring to obtain the clay-based 3D printing special mortar. According to the clay-based 3D printing special mortar, the early strength of the clay-based special mortar is improved based on the excitation effect of sodium silicate in the geopolymer.
本发明提供一种粘土基3D打印特种砂浆，以重量份数计，包括粘土，30～40份；砂，32～50份；PP纤维，0.12～0.15份；水玻璃碱渣，4～6份；氧化钙，3～5份；粉煤灰，1.5～2份；水，11～15份；减水剂，0.02～0.03份。一种粘土基3D打印特种砂浆的制备方法，包括以下步骤：S1:将粘土、砂、粉煤灰和氧化钙进行预混合；S2:加入水和水玻璃碱渣，搅拌；S3:继续加入PP纤维，再搅拌得到粘土基3D打印特种砂浆。本发明的粘土基3D打印特种砂浆，基于硅酸钠在地聚合物中的激发效应，提升粘土基特种砂浆的早期强度。
