Description

Technical Field

[0001] The utility model relates to the field of concrete body hardness detection, in particular to an aerated concrete body hardness tester. Background Art

[0002] Concrete refers to a general term for engineering composite materials in which aggregates are bonded into a whole by cementitious materials. It usually refers to a product obtained by mixing cement as a cementitious material, sand and stone as aggregates, and then mixing with water in a certain proportion. In the production process of autoclaved aerated concrete, the concrete needs to be left to stand. Before cutting, a concrete strength tester is needed to test its hardness to avoid the concrete's hardness being too high or not up to standard, thereby affecting the cutting of the concrete. The existing aerated concrete blank has a cracking phenomenon during the hardness test, causing concrete splashing and posing a safety hazard. It is inconvenient to protect during the test, and because the length of the test head is fixed, it is inconvenient to adjust its length according to the thickness of the blank, which affects the test results and brings certain adverse effects to people's use process. For this reason, we propose an aerated concrete blank hardness tester. Utility Model Content
