Description

Technical Field

[0001] The present application relates to the field of concrete testing and detection, and in particular to a self-compacting concrete testing device. Background Art

[0002] At present, self-compacting concrete is often needed in engineering fields such as construction, municipal administration, and railways. Most self-compacting concrete quality tests are carried out using ordinary concrete testing tools. Generally, small containers or shovels are used to hold the concrete multiple times and then vibrated to form the concrete. In actual use, due to manual operation, there is a lot of randomness. The amount of self-compacting concrete fillers, the drop height, and the flow rate cannot be effectively controlled. The density of the same group of test specimens is not uniform, the test data is highly discrete, the coefficient of variation is high, and the test results are inaccurate. In the case of a large number of test repetitions, the test results of self-compacting concrete cannot be truly reflected, and do not meet the requirements of JGJ / T28-2012 "Technical Specifications for the Application of Self-Compacting Concrete" that self-compacting concrete should be loaded into the test mold without stratification at one time, and should not be formed by vibrating the concrete or inserting the concrete.

[0003] In the related art, a self-compacting concrete specimen forming container is provided with a conical funnel on a fixed bracket. The conical funnel can hold at least two specimens of concrete. The concrete flows out through a discharge port at the bottom of the conical funnel to make a self-compacting concrete specimen. However, this self-compacting concrete specimen molding container can only produce one specimen at a time, and multiple specimens in the same group need to be molded multiple times; the capacity of the conical funnel is the amount required for at least two concrete specimens. In the process of making two specimens in the same group, the conical funnel is divided into two times to make the specimens. Since the concrete capacity in the conical funnel is the amount of two concrete specimens when making the first specimen, the concrete capacity is large at this time. When making the second specimen, the concrete capacity in the conical funnel is less than the amount of one specimen, that is, the amount of only one concrete specimen. At this time, the concrete capacity in the conical funnel is less than the concrete capacity when making the first specimen, that is, the concrete capacity in the conical funnel is different when making the specimens twice, resulting in inconsistent concrete discharge flow rates when making the specimens twice, and unable to truly reflect the test results of the self-compacting concrete.

[0004] Therefore, it is necessary to design a self-compacting concrete test device to overcome the above problems. Utility Model Content
