Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a high-durability hydraulic high-performance concrete, a preparation process and a preparation device. Background technique [0002] In water conservancy projects, the abrasive effect of high-speed sand-containing water flow on hydraulic concrete buildings and structures is the main cause of abrasive damage to hydraulic concrete surfaces, and it is also a common disease encountered in water conservancy and hydropower projects. Abrasive damage not only requires expensive repair work, but also directly endangers the safe operation of the project. Water conservancy projects require hydraulic high-performance concrete, which is used for buildings (or parts of buildings) that are frequently or periodically subjected to water and can ensure long-term normal use of the building under the above conditions. [0003] At present, the basic performance of hydraulic high-performance concret...
