Description

Technical Field

[0001] This application relates to the field of concrete testing, and more specifically, to a concrete air content measuring instrument. Background Technology

[0002] Concrete is a common building material widely used in construction and infrastructure projects. It is made by mixing cement, sand, aggregates, and water, and after mixing, pouring, and curing, it forms a solid structure. A concrete air content meter is a device used to measure the air content in concrete. The porosity of concrete has an important impact on its performance, including freeze-thaw resistance, durability, and strength. The determination of concrete air content is crucial to ensuring the quality and performance of concrete. Accurate air content measurement can help engineers and architects assess the freeze-thaw resistance, durability, and suitability of concrete for use under specific environmental conditions.

[0003] Currently, when removing the lid from the top of the concrete air content meter we use, we need to unscrew the bolts that fix the bowl around the body before we can disassemble the lid; when opening and closing the lid, we need to screw the bolts on multiple times, which is quite cumbersome.
