[0002] Mortar is the bonding material used for bricklaying in construction. It is made of a certain proportion of sand and binder materials and water. It is also called mortar. Common mortars include cement mortar, mixed mortar, lime mortar and clay mortar. In order to ensure the strength of the mortar bond, it is necessary to test the mortar bond strength, and there are special devices for testing it.

[0003] Current mortar bond strength testing devices typically apply a certain tensile or compressive force to the mortar specimen to simulate the external forces to which the mortar is subjected during actual use. The measurement system accurately measures the force applied to the specimen and its deformation during the stress process, thereby calculating the mortar bond strength.
