Calcium-silicon clay-based recycled aggregate concrete for 3D printing and manufacturing method of calcium-silicon clay-based recycled aggregate concrete
The invention discloses calcium-silicon clay-based recycled aggregate concrete for 3D printing and a manufacturing method of the calcium-silicon clay-based recycled aggregate concrete. The calcium-silicon clay-based recycled aggregate concrete for 3D printing is prepared from the following raw materials in parts by weight: 45-95 parts of 3D printing mortar and 5-55 parts of calcium-silicon clay-based recycled aggregate for 3D printing, the 3D printing mortar is prepared from the following materials in parts by mass: 37.9 to 48.8 parts of sand, 26.8 to 40.8 parts of a curing agent, 2.2 to 4.2 parts of an additive, 0.41 to 0.60 part of chopped fiber and 15.8 to 23.8 parts of water, the particle size of the sand is smaller than 1.18 mm; the curing agent comprises an alkali-activated cementing material. The raw materials of the calcium-silicon clay-based recycled aggregate for 3D printing are cheap and easy to obtain, so that the cost of a building 3D printing material is reduced, and the technical problem of high-efficiency and high-addition resource utilization of engineering spoil solid wastes is effectively solved.
本发明公开一种3D打印用钙硅系黏土基再生骨料混凝土及其制造方法，所述述3D打印用钙硅系黏土基再生骨料混凝土包括下列重量份原料：3D打印砂浆45～95份、3D打印用钙硅系黏土基再生骨料5～55份；所述3D打印砂浆包括以下质量份材料：砂子37.9～48.8份、固化剂26.8～40.8份、添加剂2.2～4.2份、短切纤维0.41～0.60份、水15.8～23.8份；所述砂子粒径小于1.18mm；所述固化剂包括碱激发胶凝材料。由于本发明所用3D打印用钙硅系黏土基再生骨料原材料价廉易得，降低了建筑3D打印材料成本，并有效解决了工程弃土固体废弃物高效高附加资源化利用技术难题。
