Description

Technical Field

[0001] This utility model relates to the field of building inspection technology, and in particular to a device for testing the bonding strength of plaster mortar in concrete structures for engineering applications. Background Technology

[0002] Plastering mortar, applied to the surface of a building, not only provides a smooth surface but also protects the walls and improves the building's durability. Common quality problems with plastering mortar include cracking, hollowing, and peeling. These issues are not only related to the mortar's low water retention but are also primarily due to its low bonding strength. Therefore, testing the bonding strength of plastering mortar is a very important task.

[0003] Currently, there are two methods for assessing the bonding strength of plastering mortar: ultrasonic testing and penetrant testing. The ultrasonic testing method uses changes in the propagation speed of ultrasonic waves to determine the bonding condition between the mortar and the substrate. Its advantage is that it is a non-contact test that does not damage the sample. However, its disadvantage is that it requires sophisticated equipment and is easily affected by environmental noise, leading to unstable test results. The penetrant method involves injecting liquid or gas into the gap between the mortar and the substrate, and then assessing the bonding strength by changing the pressure. Its advantage is that it allows for continuous monitoring, but its disadvantage is that it has a limited scope of application and is not suitable for all types of mortar materials.
