Description

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 determine the performance of the entire concrete by affecting the performance of the mortar. The concrete air content meter is mainly composed of a measuring bowl, a bowl cover, a small faucet connecting the upper and lower parts of the bowl cover, an air outlet valve for exhaust, a valve stem for controlling the opening and closing of the valve, a fine-tuning valve for adjusting the air pressure, a pressure gauge for measuring the air pressure, an air chamber and an air pump for inflating the air chamber. The bowl cover is connected to the measuring bowl, and the air outlet valve, air pump, fine-tuning valve and door stem are all installed on the upper wall of the bowl cover. The pressure gauge is installed at the upper end of the vertically arranged air outlet valve. When conducting the test, the measuring bowl is filled with the concrete mixture sample, the air chamber between the bowl cover and the measuring bowl is filled with water, and the air chamber is filled with gas with a pressure of about 0.1Mpa. Therefore, the sealing requirement between the measuring bowl and the bowl cover is relatively high. If the air tightness between the measuring bowl and the bowl cover is not good or affects the accuracy of the test results, in the prior art, after the concrete is filled into the measuring bowl and compacted, the excess concrete on the port of the measuring bowl is manually scraped flat with a slat, and then the port of the measuring bowl is wiped clean with a rag to avoid affecting the air tightness after the cover is buckled. There are problems such as uneven manual force during scraping, and the scraped concrete sticks to the port of the measuring bowl and needs to be manually wiped clean, wasting manpower, etc. Utility Model Content
