3D printing construction mortar workability test device and application

Abstract

The invention relates to a 3D print building mortar workability testing device and application. The 3D print building mortar workability testing device comprises an extruding device, a support and a load, wherein the extruding device consists of an injection cylinder body and a push rod matched with the injection cylinder body; 3D print building mortar is arranged in the injection cylinder body; the support is a conical body the upper part of which is provided with a circular ring; the extruding device is fixed by utilizing the circular ring; the load is arranged on the upper end of the push rod; the extruding time of the 3D print building mortar can be tested by utilizing the device. Compared with the prior art, the 3D print building mortar workability testing device has the advantages that the working performances (extruding time) of different print mortar can be represented effectively; quantitative indexes can be given for the 3D print mortar by the method, and the basis is provided for evaluating the performances of the 3D print material; by determining the workability of the print material by the method, the components of the material can be allocated so as to conform to requirements on the performances of the print material at different environments and under different working conditions.

Description

technical field [0001] The invention belongs to the technical field of building materials and building construction, and in particular relates to a workability test device and application of 3D printing building mortar. Background technique [0002] 3D printing is a transformative and digital additive manufacturing technology that adds materials layer by layer to manufacture three-dimensional objects. Additive manufacturing technology is a technology that uses the method of gradually accumulating materials to manufacture solid parts. Compared with the traditional material removal-cutting processing technology , is a "bottom-up" manufacturing method. It integrates and infiltrates technologies such as information, materials, biology, and control. 3D printing technology is good at solving personalized, complex and difficult production technologies. [0003] Using 3D printing technology, not only small pieces of handicrafts can be printed, but even cars can be printed, and it ...
