Concrete material for building 3D printing, preparation method thereof and 3D product
The invention provides a concrete material for building 3D printing, a preparation method thereof and a 3D product, and relates to the technical field of building 3D printing materials. The invention relates to a concrete material for building 3D printing. The concrete material comprises the following components in parts by weight: 250-450 parts of cement; 300 to 600 parts of an active mineral admixture; 1100 to 1300 parts of aggregate; 0.2 to 1 part of a stabilizer; 0.1 to 1 part of starch ether; 0.1 to 1.5 parts of a binder; 0.05 to 1 part of a defoaming agent; 0.5 to 5 parts of fiber; wherein the active mineral admixture comprises gold mine tailings. The concrete material for building 3D printing has the characteristics of high strength, good adhesive property, difficult collapse and good pumpability; according to the concrete material for building 3D printing, the gold mine tailings are used, so that waste resources can be fully utilized, the cost is reduced, and the concrete material has relatively high environmental benefits and social benefits.
本申请提供一种用于建筑3D打印的混凝土材料、其制备方法以及3D制品，涉及建筑3D打印材料技术领域。一种用于建筑3D打印的混凝土材料，所述混凝土材料按照重量份计包括以下组分：水泥250～450份；活性矿物掺合料300～600份；骨料1100～1300份；稳定剂0.2～1份；淀粉醚0.1～1份；粘结剂0.1～1.5份；消泡剂0.05～1份；纤维0.5～5份；其中，所述活性矿物掺合料包括金矿尾矿。本申请的用于建筑3D打印的混凝土材料具有强度较高，粘结性能好，不易塌落，可泵送性能好的特点；该用于建筑3D打印的混凝土材料使用了金矿尾矿，使得废弃物的资源能够被充分利用，降低了成本，具有较高的环境效益和社会效益。
