[0002] Before construction, various data of concrete need to be tested, and the vertical load of concrete is the core of the test. High-ductility concrete is a building material with high ductility, high damage resistance, high durability, high strength (compression and tension) and good crack control ability, also known as "bendable concrete". It has a wide range of applications. High-ductility concrete can be used to make prefabricated components, such as wall panels, floor slabs, etc. These components have high strength and ductility, which can reduce damage and cracking and improve the quality of construction. These prefabricated components need to focus on testing their vertical load to ensure that the concrete meets the standards. During the test, debris will be generated when the components are broken, which will not only affect the surrounding test environment, but also have an adverse effect on the observation of cracks.
