Description

Technical Field

[0001] The present application relates to the technical field of concrete quality detection, and in particular to a device for continuously measuring the amount of ammonia released in concrete. Background Art

[0002] Fly ash is one of the raw materials used in concrete. It undergoes a secondary reaction with concrete to form a water-insoluble calcium silicate hydrate gel. This not only reduces the possibility of dissolution but also fills the pores within the concrete, improving its strength and impermeability. However, fly ash produced through denitrification contains a high level of residual ammonium salts. During the concrete mixing process, due to the alkaline conditions and high amounts of heat, the ammonium salts decompose, releasing ammonia gas. This release of ammonia can negatively impact concrete performance and the environment. Therefore, it is necessary to measure the ammonia released by concrete to determine if the concrete is suitable for use.

[0003] The Chinese patent with announcement number CN206618714U discloses a device for measuring the time-dependent release of ammonia in concrete. A fence frame and a sample container placed on the fence frame are provided in a sealed box. The air outlet of the blower is connected to the air inlet of the sealed box through a ventilation hose. The air outlet of the sealed box is connected to the upper end of the air inlet pipe provided on the glass washing bottle through the ventilation hose. The lower end of the air inlet pipe is inserted into the absorption solution contained in the glass washing bottle. The glass washing bottle is also provided with an air outlet pipe connected to the outside air and an ammonia sensitive electrode for measuring ammonia. The lower end of the ammonia sensitive electrode is inserted into the absorption solution, and the upper end is connected to the measuring host through a connecting wire. The entire device of the utility model is simple to operate, convenient to connect and disassemble, and has strong detection continuity. It can monitor the release of ammonia in fresh concrete in real time, filling the gap in this field and facilitating the guidance of concrete production and construction.

[0004] When the above-mentioned device for measuring the time-released ammonia in concrete detects ammonia, it is necessary to pass ammonia-containing gas into the absorption solution, and then detect the absorption solution through the measuring host. This detection method requires the introduction of a certain amount of gas before detection, and cannot continuously detect the ammonia concentration in real time. It is not effective for measuring the time-released ammonia in concrete. Utility Model Content
