Description

Technical Field

[0001] The utility model relates to the technical field of concrete strength detection, in particular to a concrete strength detection device. Background Art

[0002] Concrete refers to cement concrete obtained by mixing cement as the binder, sand and stone as aggregates and water in a certain proportion. It is widely used in civil engineering. A large amount of concrete is needed during the construction process. Before use, the strength of the concrete needs to be tested with strength testing equipment to facilitate subsequent use.

[0003] The existing concrete strength testing device lacks a buffer structure, so when testing the concrete test block, the pressure plate often presses on the base while the concrete test block is crushed, which easily causes the pressure plate to damage the base. When the concrete test block is crushed, it is very easy to splash onto the operator, thereby injuring the operator. For this reason, we propose a concrete strength testing device.
