Novel underwater 3D printing concrete material and printing method thereof
The invention relates to the technical field of building materials and civil construction technologies, in particular to a novel underwater 3D printing concrete material and a printing method thereof. The concrete disclosed by the invention is not doped with a flocculating agent or a tackifier, so that the concrete is easily extruded from a printing nozzle, the interlayer bonding performance is good after the concrete is printed and placed, and an interface gap is not formed. The underwater 3D printing concrete provided by the invention is not influenced by the anti-dispersing agent, so that the mixing proportion design is more flexible, the application range is wider, the strength after molding is higher, and the strength can reach C40 or above when the underwater 3D printing concrete is cured in water.
本发明涉及建筑材料和土建施工技术技术领域，尤其涉及一种新型的水下3D打印混凝土材料及其打印方法。本发明所述混凝土由于不掺加絮凝剂或者增粘剂，易于从打印喷嘴中挤出，打印放置后层间粘结性能佳，不会形成界面缝隙。本发明提供的水下3D打印混凝土由于不受抗分散剂的影响，其配合比设计更加灵活且适用范围更广，成型后强度更高，在水中养护能达到C40以上的强度。
