Problems solved by technology

[0003] 1. Because high-performance concrete is relatively viscous, it is difficult for general mixing equipment to mix evenly. To make the mixing process go smoothly, you can only prolong the mixing time or increase the water-cement ratio, which not only increases the amount of gel material, Moreover, concrete with good cohesion cannot be obtained. Concrete with poor cohesion has poor early volume stability and is easy to crack
[0004] 2. The inner wall of the existing high-performance concrete mixing equipment is easy to bond with concrete, which requires manual cleaning on a regular basis, which affects the construction progress

Description

technical field [0001] The invention belongs to the technical field of building construction equipment and relates to concrete mixing technology, in particular to a vibration mixing device and a vibration mixing method for high-performance concrete. Background technique [0002] High-performance concrete is considered to be the most comprehensive concrete in the world due to its many excellent properties such as high durability, high strength, high volume stability and high workability. Especially in recent years, this concrete technology is developing rapidly and has been applied to many major practical engineering projects. However, in practical applications, there are still the following technical problems in high-performance concrete mixing: [0003] 1. Because high-performance concrete is relatively viscous, it is difficult for general mixing equipment to mix evenly. To make the mixing process go smoothly, you can only prolong the mixing time or increase the water-ceme...
