Concrete slurry for underwater 3D printing and construction method
The invention discloses concrete slurry for underwater 3D printing, and belongs to the technical field of building materials, the slurry comprises a main material, an auxiliary material and a recycled material, the main material comprises, by weight, 100-120 parts of cement, 15-30 parts of silica fume, 10-15 parts of coral sand, 8-12 parts of quartz sand and 35-40 parts of water; the auxiliary material is prepared from 1 to 2.5 parts of a water reducing agent, 1 to 1.5 parts of an anti-dispersing agent, 0.5 to 1 part of cellulose and 0.8 to 1.5 parts of vegetable gum; the recycled material is a marine recycled plastic body and comprises 20-35 parts of polyethylene glycol terephthalate and/or polystyrene and/or polypropylene and/or polyethylene. The underwater 3D printing concrete slurry provided by the invention can meet the fluidity during printing and also meets the requirement of dispersion resistance, and the marine litter recycled material is combined with the applied substance, so that the substance can be consumed on the premise of not influencing the practicability of the product provided by the invention, and environmental protection is facilitated.
本发明公开了一种水下3D打印的混凝土浆体，属于建筑材料技术领域，所述浆体包括主料、辅料及回收料，按重量份数计，所述主料由100‑120份水泥、15‑30份硅灰、10‑15份珊瑚砂、8‑12份石英砂、35‑40份水组成；所述辅料由减水剂1‑2.5份、抗分散剂1‑1.5份、纤维素0.5‑1份、植物胶0.8‑1.5份组成；所述回收料为海洋回收塑料体，包括聚对苯二甲酸二醇酯和/或聚苯乙烯和/或聚丙烯和/或聚乙烯20‑35份。本发明的水下3D打印混凝土浆体既可以满足打印时的流动性，也具有符合抗分散性的要求，而且将海洋垃圾回收材料与申请的物质相结合，可以在不影响本发明产品的实用性的前提下，也能消耗此类物质，有助于环保。
