| description | The invention discloses a building material compression resistance and damage dynamic test method based on CT scanning. The method comprises the following steps: obtaining a to-be-tested building material standard test piece; installing the to-be-tested building material standard test piece in the loading device and loading the to-be-tested building material standard test piece, and obtaining the cracking load, the peak load and the limit load of the to-be-tested building material standard test piece; replacing a building material standard test piece in the loading device, and respectively applying 10% peak load, cracking load, peak load and limit load to the test piece; dynamically scanning the section of the test piece under each stage of load through a CT scanning instrument; recording the overall macroscopic deformation condition and the internal section damage accumulation condition of the test piece under each stage of load, and determining the compressive strength, the compressive strain and the damage |
