Description

A production system for manufacturing high-volume slag-fly ash concrete

technical field

The utility model relates to the field of construction equipment, in particular to a production system for manufacturing high-volume slag-fly ash concrete.

Background technique

Concrete cracking not only affects the strength of concrete, but more importantly reduces the durability of concrete. Concrete cracking has design reasons as well as material reasons. As far as the material is concerned, it mainly includes the mineral composition of cement, the fineness of cement and the amount of cement in concrete. In order to prevent concrete cracking, cement with low tricalcium aluminate content and appropriate specific surface area should be used, and the amount of cement should be reduced as much as possible. The literature shows that the use of fly ash to replace part of the cement can reduce the temperature rise caused by the heat of hydration of concrete, prevent concrete cracking, and improve the durability of concrete without affecting the strength of concrete. Therefore, fly ash The promotion and use of concrete has become one of the development trends.

When the existing concrete mixer is mixing and mixing to produce high-volume fly ash concrete, due to the unevenness of the ground on the construction site, the concrete mixer is usually easy to tilt. After tilting, the amount of cement that can be contained in the mixing drum is reduced, and the cement is easy to flow In the downward part of the mixing drum, the concrete is mixed unevenly, which affects the production quality of high-volume fly ash. Because it cannot adapt to the ground of the construction site, the concrete mixer is tilted, which affects the output and quality of concrete, thereby reducing the quality of the concrete. Availability of existing concrete mixers.
