Abstract: The present disclosure belongs to the technical field of mortar, and in particular, to three-dimensional (3D) printed mortar and a preparation method therefor, and a 3D printing method for mortar. The mortar includes: 50-70 parts of ordinary Portland cement; 6-14 parts of sulphoaluminate cement; 2-20 parts of slag powder; 18-22 parts of fly ash; 0.25-2 parts of accelerator; 0.05-0.45 parts of cellulose ether; 0.1-0.3 parts of naphthalene series water reducer; 0.4-0.6 parts of redispersible rubber powder; 0.1-0.5 parts of defoamer; 0.1-0.5 parts of early strength agent; 0.4-1.0 part of polypropylene fiber; 100-120 parts of fine aggregate; and 30-40 parts of water. A 3D printing speed of the mortar of the present disclosure can be stably kept within 150-200 mm/s by using the above raw materials at a reasonable ratio.

Abstract: The present disclosure relates to an electronic control system based on three-dimensional (3D) concrete printing, including: a control card, a three-way axis driver, a printing device head, a servo motor, a camera and a monitoring system. The monitoring system includes the camera and a display module. The control card is configured to parse a 3D digital model of a to-be-printed object into a program instruction. The three-way axis driver is configured to receive the program instruction to drive the servo motor. The servo motor is configured to control movement of the printing device head. The camera is configured to acquire video data of a discharge port of the printing device head in real time. The monitoring system is configured to remotely monitor concrete discharge conditions of the printing device head according to the camera. The control card is connected with the three-way axis driver based on an EtherCAT bus.
