[0002] Carbonation of concrete is a kind of chemical corrosion suffered by concrete. CO2 gas in the air penetrates into the concrete through the pores of hardened concrete, and reacts chemically with its alkaline substances to produce carbonates and water. The process of reducing the alkalinity of concrete is called concrete carbonation. During the carbonation of concrete, carbonates will gradually penetrate into the interior of the concrete, lowering the pH value, further causing steel corrosion, and thus threatening the structural safety of concrete buildings. Therefore, a concrete carbonation test chamber is needed to conduct carbonization experiments on concrete.

DETAILED DESCRIPTION
[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0026] like Figure 1-7 As shown, a concrete carbonization test box includes a test box body 1, a ring groove 2 is opened on the front side of the test box body 1, placement grooves 3 are opened on both sides of the annular groove 2, a first air bag 5 and a second air bag 6 are fixedly connected to the inner walls of the two placement grooves 3 respectively, first clamping columns 7 are fixedly connected to both ends of the first air bag 5, and second clamping columns 8 are fixedly connected to both sides of the inner wall of the second air bag 6. A box door 9 is arranged on the front side of the test box body 1, and an observation window is arranged on the box door 9, which is not drawn in the figure. A sealing frame 10 is fixedly connected to one end of the box door 9, first clamping grooves 11 are opened on both ends of the sealing frame 10, and second clamping grooves 12 are opened on both sides of the inner wall of the sealing frame 10.
[0027] In this embodiment, symmetrically distributed slots 13 are provided on both sides of the front side of the test box 1 corresponding to the annular groove 2 and extend into the placement groove 3, and symmetrically distributed plug boards 14 are fixedly connected to both sides of the sealing frame 10 corresponding to one end of the box door 9, and the shapes of the multiple plug boards 14 and the slots 13 are adapted;
[0028] Since there are multiple inserting plates 14 and slots 13, the first airbag 5 and the second airbag 6 can be squeezed at multiple positions at the same time, further improving the sealing performance.
[0029] In this embodiment, both ends of the test box 1 are symmetrically fixedly connected to the limit frame 15, and both ends of the box door 9 are symmetrically fixedly connected to the elastic plate 16, and the ends of the multiple elastic plates 16 that are far away from each other are fixedly connected to the triangular block 17;
[0030] The elastic plate 16 is inserted into the limit frame 15. When the triangular block 17 contacts the limit frame 15, the elastic plate 16 will bend inward. When the box door 9 and the test box body 1 are completely in contact, the triangular block 17 is stuck on the other side of the limit frame 15 through the resetting effect of the elastic plate 16, completing the limitation of the elastic plate 16.
[0031] In this embodiment, the inserting plates 14 are provided with inclined surfaces at one end close to each other, and squeeze the first airbag 5 and the second airbag 6, so that the first airbag 5, the second airbag 6 and the sealing frame 10 can be in closer contact, further ensuring the sealing performance.
[0032] In this embodiment, the first clamping column 7 and the second clamping groove 12 are matched in shape, and the second clamping column 8 and the first clamping groove 11 are matched in shape, so that the sealing frame 1 can be limited in position.
[0033] In this embodiment, a plurality of evenly arranged placement plates are fixedly connected to the inner wall of the test box 1, and atomizing nozzles are fixedly penetrated above the placement plates corresponding to the inner wall of the test box 1. The placement plates are used to place concrete specimens, and the atomizing nozzles can provide moisture to the inside of the test box 1 to ensure the humidity inside the test box 1.
[0034] It should be noted that the utility model is a concrete carbonization test box. When in use, after the concrete specimen is placed on the placement board, the sealing frame 10 is inserted into the annular groove 2, and the sealing frame 10 is clamped between the first airbag 5 and the second airbag 6. At this time, the first clamping column 7 is clamped in the second clamping groove 12, and the second clamping column 8 is in the first clamping groove 11, completing the position limitation of the sealing frame 10, thereby improving the sealing between the box door 9 and the test box body 1, preventing the external environment from interfering with the internal environment of the test box during the carbonization experiment, ensuring the stability of the internal environment of the test box body 1, and preventing the effect of the carbonization experiment from being affected;
[0035] When the sealing frame 10 is inserted into the annular groove 2, the inserting plate 14 is also inserted into the slot 13, thereby squeezing the first airbag 5 and the second airbag 6, so that the first airbag 5, the second airbag 6 and the sealing frame 10 are in closer contact, thereby further strengthening the sealing between the test box 1 and the sealing frame 10;
[0036] At the same time, the elastic plate 16 is inserted into the limit frame 15. When the triangular block 17 contacts the limit frame 15, the elastic plate 16 bends inward. When the box door 9 and the test box 1 are completely in contact, the triangular block 17 is clamped on the other side of the limit frame 15 by the resetting effect of the elastic plate 16, completing the limit of the elastic plate 16.
[0037] After the experiment is finished, it is only necessary to press the elastic plate 16 to separate the triangular block 17 and the limiting frame 15 , so that the test box 1 and the box door 9 can be separated.
[0038] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
