Nano graphene concrete material for building 3D printing and preparation method thereof
The invention provides a nano graphene concrete material for building 3D printing and a preparation method thereof, and the nano graphene concrete material for building 3D printing is prepared from the following components in parts by weight: 100 parts of cement, 0.1 to 50 parts of dense filler, 0.1 to 30 parts of mineral admixture, 0.01 to 0.15 part of graphene oxide, 0.1 to 2.5 parts of dispersing agent, 0.1 to 3.0 parts of thixotropic agent, 0.1 to 1.5 parts of accelerator, 0.1 to 2.0 parts of a thickening water-retaining agent, 0.01 to 0.1 part of a defoaming agent and 0.1 to 2.0 parts of fibers. The nano graphene concrete material for building 3D printing, provided by the invention, has the advantages of controllable setting time and better fluidity, and can obtain early strength in the printing process so as to ensure continuous printing; water leakage is prevented, and the interlayer bonding strength is high; and the printing precision is good, and high-precision building components can be printed.
本发明提供了一种建筑3D打印用纳米石墨烯混凝土材料及其制备方法，其中，建筑3D打印用纳米石墨烯混凝土材料按重量份计包括100份的水泥，0.1‑50份的密实填料，0.1‑30份的矿物掺合料，0.01‑0.15份的氧化石墨烯，0.1‑2.5份的分散剂，0.1‑3.0份的触变剂，0.1‑1.5份的速凝剂，0.1‑2.0份的增稠保水剂，0.01‑0.1份的消泡剂以及0.1‑2.0份的纤维。本发明提供的建筑3D打印用纳米石墨烯混凝土材料凝结时间可调控，流动性较佳，在打印过程中可获得早期强度，以保证打印的继续进行；具有防漏水和较高的层间粘结力强度；打印精度较佳，可打印高精度建筑构件。
