Description

Technical Field

[0001] The utility model belongs to the technical field of concrete detection, and in particular relates to a device for detecting the sensitivity of a concrete polycarboxylate water reducer to water consumption. Background Art

[0002] Polycarboxylate superplasticizers, as third-generation high-performance water reducers, have been widely used in concrete. However, due to my country's vast territory, the complex variety of concrete raw materials across different regions, and the production process being affected by factors such as fluctuations in sand and gravel moisture content, temperature variations, and dosage fluctuations, the sensitivity of polycarboxylate superplasticizers to concrete has become increasingly prominent. This is primarily manifested in the fact that when polycarboxylate superplasticizers are directly applied to concrete, they often exhibit sensitivity issues such as poor compatibility with cement and mineral admixtures, unstable concrete performance, easy segregation, or significant slump loss. These sensitivity issues can lead to an inability to meet construction site requirements, significantly hindering the promotion and use of polycarboxylate superplasticizers.

[0003] There is no clear national standard for testing the water usage sensitivity of polycarboxylate superplasticizers in concrete. Traditional evaluation methods primarily refer to JC / T1083-2008, "Test Method for Compatibility of Cement and Superplasticizers." This method indirectly analyzes the water usage sensitivity of polycarboxylate superplasticizers by primarily using a neat slurry test, adjusting the water-cement ratio for each test, and testing fluidity. This method is cumbersome and inefficient. Therefore, it is crucial to develop a simple device for testing the water usage sensitivity of polycarboxylate superplasticizers in concrete that can directly measure the water usage sensitivity of polycarboxylate superplasticizers in concrete, in order to meet the future application needs of polycarboxylate superplasticizers.

[0030] Dispersion container 2 is removably fixed to base 1. A valve 21 is provided at the bottom of dispersion container 2, connecting the inside and outside of dispersion container 2. Dispersion container 2 is used to inject cement slurry. When valve 21 is opened, cement slurry flows out from valve 21. Because dispersion container 2 requires stirring and dispersing, it needs to be fixed to base 1 during use to prevent shaking of dispersion container 2 during stirring and dispersing of cement slurry.

[0031] The disperser 3 is mounted on the base 1, and its dispersing disc 31 can be inserted into the dispersion container 2. The disperser 3 rapidly stirs and disperses the cement paste in the dispersion container 2. The stirring speed of the disperser 3 can be set according to actual needs. The specific structure of the dispersing disc can be determined according to actual needs, such as a dispersing blade type, a sharp tooth type, a flat disc serrated type, a three-paddle type, a disc type, or other types of dispersing discs.

[0032] The titration device 4 is detachably fixed on the pedestal 1, and the dropper 41 of the titration device 4 is connected to the dispersion container 2. The titration device 4 can achieve the purpose of automatically adding the amount of water used for cement.

[0034] During use, the present invention is characterized by injecting cement slurry into dispersion container 2, which is then fixed to base 1. The dispersing disc of disperser 3 is inserted into dispersion container 2, and water is added to titration device 4. Detection container 5 is placed below valve 21. Titration device 4 drips a predetermined amount of water into dispersion container 2, activates disperser 3, and opens valve 21. As the cement slurry rapidly disperses, the time it takes for detection container 5 to be filled with a preset amount of slurry is observed, providing a visual indicator of changes in cement slurry viscosity.

[0035] In some embodiments, two symmetrical clamping devices are provided on the pedestal 1 , and the two clamping devices can be clamped on both sides of the dispersion container 2 to achieve detachable fixation of the dispersion container 2 on the pedestal 1 .

[0039] In some embodiments, the base 6 is a vacuum suction cup base, and the base 6 can absorb and fix the dispersion container 2 .

[0040] In this embodiment, the dispersion container 2 can be fixed by a vacuum suction cup base.

[0041] In some embodiments, the dispersion container 2 is a stainless steel container made of stainless steel.

[0042] In some embodiments, the top surface of the dispersion container 2 has an opening, a detachable cover on the opening is provided with a container cover, and the dispersion disk extends through the container cover into the dispersion container 2. In specific implementation, a sealing ring can be provided between the connecting rod of the dispersion disk and the container cover for sealing.

[0044] The container cover can avoid splashing of the solution when the cement paste is quickly stirred and dispersed.

[0045] In some embodiments, the disperser 3 is a lifting disperser 3 .

[0046] Before use, the dispersion plate of the disperser 3 can be raised to facilitate taking and placing the dispersion container 2 .

[0047] In some embodiments, the disperser 3 is an electric disperser 3 .

[0048] The power part of the electric disperser 3 is the motor 32 . The motor 32 is preferably located above the dispersion container 2 . The motor 32 is fixed to the base 1 via a mounting bracket.

[0049] In some embodiments, the valve 21 is implemented as a faucet.

[0050] The faucet is easy to switch on and off, making it convenient for testing and use.

[0051] In some embodiments, the detection container 5 is a transparent container, and scales are vertically arranged on the outer wall of the transparent container.

[0052] The detection container 5 can be a transparent container made of acrylic material. The transparent container can facilitate the user to observe whether the cement paste in the detection container 5 has reached a preset scale.

[0054] The design of this embodiment can realize the automatic timing function. When in use, after opening the valve 21, by pressing the start button, the timer starts timing. When the liquid level meter detects the preset liquid level, the timer stops timing and the timing time is displayed on the display.

[0055] During actual implementation, a controller may be added, and the level gauge, timer, start button, and display may be connected to the controller respectively. The controller may be a controller based on a PLC architecture or a controller based on a single chip architecture.
