Background Art

The slump of fresh concrete is an important indicator that needs to be considered and measured in concrete design and construction. In engineering construction, the slump of fresh concrete often needs to be measured, so the slump cone is a tool that is often needed in the use of concrete. In recent years, due to the promotion and application of new technologies and products such as high-strength and high-performance concrete, many fresh concretes have high viscosity. After the slump measurement, the inner wall of the slump cone is prone to adhere to the viscous cement paste. If the slump cone is not cleaned in time, the viscous cement paste hardens on the inner wall of the slump cone, making the inner wall of the slump cone rough and the diameter of the cylinder smaller, affecting the accuracy of the slump measurement, and even making the slump cone unqualified. Therefore, a device for quickly cleaning the inner wall of the slump cone is urgently needed in construction.
