Description

Technical Field

[0001] The present invention relates to the technical field of concrete testing equipment, and particularly relates to a concrete slump testing device. Background Art

[0002] A slump tester is a device used to measure the slump of fresh concrete. It is mainly applied at construction sites of building projects, road and bridge projects, etc., as well as in the laboratories of concrete production enterprises. At construction sites, it can timely detect the slump of fresh concrete to determine whether the workability of the concrete meets the construction requirements, such as whether it is convenient for pouring, vibrating, etc.; in the laboratories of concrete production enterprises, it can be used to control the mix design of concrete, and adjust the dosages of materials such as cement, water, and aggregates in the concrete according to the slump test results to ensure that the quality and performance of the concrete meet the design requirements.

[0003] In the traditional use of existing concrete slump testing devices, often two people are required to cooperate. One person fills the slump cone with the concrete to be tested, and the other person steps on and holds the slump cone and uses a tamper to compact the concrete. The operation is rather cumbersome and laborious. If slumping occurs on one side of the concrete, multiple filling tests are needed, greatly increasing the workload of the operators. Moreover, the lifting of the slump cone and the measurement of the concrete height need to be carried out step by step in coordination, resulting in poor detection efficiency of the device.
