Technical Field

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

[0002] The concrete air content meter is used to measure the air content in the mixture. Concrete can be divided into two components, namely coarse aggregate and mortar. The size of the coarse aggregate particle size has almost no direct effect on the air content. The introduced bubbles are distributed in the fine particles of concrete, namely the mortar, and the performance of the entire concrete is determined by the performance of the mortar.

[0003] However, the test results of the existing concrete air content measuring instrument are very simple. When inserted into the concrete, it can only measure one part of it, and cannot be moved or adjusted. Therefore, it is impossible to detect the air content of each position of the concrete, resulting in inaccurate test results and affecting the test effect. To this end, we provide a concrete air content detection device to solve the above problems. Utility Model Content
