On June 10, 2022, CCPA and CBMF jointly approved and issued 2 CCPA standards, Test Methods for Basic Mechanical Properties of 3D Printed Concrete and Test Methods for Printability of 3D Printing Fresh Concrete, which shall be implemented from October 10, 2022.

Test Methods for Basic Mechanical Properties of 3D Printed Concrete is applicable to the basic mechanical properties test of 3D printed concrete using extrusion molding technology. The release and implementation of this standard will standardize the testing and evaluation of the mechanical properties of 3D printed concrete, effectively promoting the healthy development of the 3D printed concrete field.

Test Methods for Printability of 3D Printing Fresh Concrete is applicable to the performance test of 3D printing fresh concrete mixtures using extrusion molding technology in construction projects. The release and implementation of this standard can guide the design and performance evaluation of 3D printed concrete materials, providing technical basis and standard guarantee for the engineering application and promotion of 3D printed concrete.
