3D printing tough concrete material and preparation method thereof
The invention discloses a 3D printing tough concrete material. The material is characterized by comprising the following components in percentage by weight: 25-45% of cement, 8-25% of a mineral admixture; 1.5%-5.0% of fibers; 25 -50 % of fine aggregate; and 0.8%-1.5% of a superplasticizer. The concrete disclosed by the invention is simple in raw material composition and rich in source; the consumption of the 3D printing concrete material can be reduced; and the production cost is reduced. The 3D printing concrete material has excellent impermeability; and the whole concrete structure has goodintegrity, ductility and anti-seismic energy dissipation performance.
本发明公开了一种3D打印韧性混凝土材料，其特征在于，按照重量百分比计，该混凝土材料包含以下组分且各组分含量为：水泥25～45％；矿物掺合料8～25％；纤维1.5～5.0％；细集料25～50％；超塑化剂0.8～1.5％。本发明的混凝土原料组成简单且来源丰富，能够降低3D打印混凝土材料用量，降低生产成本。本发明的3D打印混凝土材料具有优异的抗渗性，整个混凝土结构具有良好的整体性、延性以及抗震耗能性能。
