[0002] Carbonation-resistant recycled concrete is a new type of concrete made by crushing, washing, and grading waste concrete blocks, mixing them in a certain proportion to partially or completely replace natural aggregates such as sand and gravel (mainly coarse aggregates), and then adding cement and water. Adding reinforcing agents to carbonation-resistant recycled concrete results in high-strength carbonation-resistant recycled concrete. The production and processing of carbonation-resistant recycled concrete requires the use of a mixing device. Concrete mixing devices are mainly of two types: vertical and horizontal. Existing vertical mixing devices typically only use horizontally positioned mixing blades, which easily causes stratification of coarse and fine aggregates, making it difficult to fully improve the uniformity of mixing and affecting mixing efficiency.
