Description

Technical Field

[0001] The utility model relates to the field of concrete experimental equipment, in particular to a water reducing agent adding device. Background Art

[0002] Concrete is widely used in modern buildings and infrastructure. In order to improve the performance of concrete during the construction process, concrete water reducers need to be added. Concrete water reducers are used to improve the fluidity and plasticity of concrete without increasing the cement content, while improving the strength and durability of concrete. Since the addition of water reducers with different parameters will affect the fluidity, plasticity, and compressive strength of concrete, it is necessary to evaluate the various performances of concrete under different addition amounts through experiments in the laboratory. The traditional method of adding concrete water reducers mainly uses weighing instruments for experimenters to measure. The above method has the defect that the experimenters weighing and adding water reducers will consume a lot of time, especially when a large number of experiments need to be carried out. This method is inefficient. At the same time, the experimenters need to import the sample data into the computer after recording it. When the number of samples is large, it will lead to difficulties in recording the experimental data. It is difficult to accurately record the corresponding addition amount, which easily leads to data confusion. There will be safety hazards in the process of manually adding water reducers to the samples. Therefore, in order to solve the above problems, a water reducer adding device is needed.
