Description

Technical Field

[0001] The present application relates to the technical field of strength detection, and in particular to a building concrete strength detection device. Background Art

[0002] Concrete is one of the most important civil engineering materials today. It is an artificial stone material made of cementitious materials, granular aggregates, water, and, if necessary, admixtures and additives in a certain proportion. It is evenly mixed, compacted, and hardened. During the use of concrete, it must meet certain standards before it can be used. Therefore, a concrete strength tester is needed to test the compressive strength of concrete.

[0003] When testing the strength of concrete, the rebound method is usually used to test the strength of concrete. If a concrete surface with a loose layer, slurry, or honeycomb surface is encountered, it is necessary to grind it with a grindstone first. This process is not only tiring, but the powder generated during grinding will fly into the air, affecting the surrounding environment, and is not environmentally friendly and safe enough.
