Abstract

The invention discloses a high fluidity mortar for 3D printing. The mortar comprises following raw materials in parts by weight: 55 to 75 parts of sulfoaluminate cement, 15 to 35 parts of silicate cement, 50 to 80 parts of blast furnace slag, 2 to 8 parts of precipitated barium sulfate, 15 to 35 parts of basalt, 1 to 2 parts of calcium sulfate, 1 to 3 parts of nylon fiber, 0.5 to 1.2 parts of water reducer, 1 to 2 parts of antifoaming agent, 0.6 to 1.2 parts of thickening agent, and 30 to 50 parts of water. The fluidity of the mortar is good, thus the printing difficulty is reduced, the cracking and bubbling phenomenon caused by bad uniformity of materials is avoided, the mortar has excellent mechanical properties, the binding property is good, the mortar is easy for construction, at the same time, after the mortar is moulded, the curing speed is fast, and the mortar is suitable for 3D construction printing.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a high-fluidity mortar for 3D printing. Background technique [0002] In recent years, 3D printing has achieved rapid development, and its application has involved many fields. In the field of construction, 3D printing technology can improve construction efficiency and save resources. 3D printing mortar is a new technology applied to concrete and mortar building construction based on 3D printing technology. Its main working principle is to pass the configured slurry through the extrusion device, under the control of 3D software, according to the pre-set In the printing process, the mountain nozzle is extruded for printing, and finally the designed components are obtained. [0003] With the emergence of 3D printing mortar technology, ordinary mortar can no longer meet its technical requirements, and higher requirements are put forward for the printed slurry. At present, ther...
