DESCRIPTION

This CCPA standard specifies the general provisions of test methods for basic mechanical properties of 3D printed concrete, including test methods for compressive strength, elasticity modulus under static compressive stress, flexural tensile strength, splitting tensile strength and shear strength.

This CCPA standard is applicable to the basic mechanical properties tests of 3D printed concrete using extrusion molding process.
