Abstract

The invention discloses a concrete rust protection and reinforcement device and method based on an electroosmosis technology. Nano-silica and methyl sodium silicate are injected into reinforced concrete with an electrochemical reaction technology, the nano-silica penetrates through the concrete sample and forms a protective layer, and chlorine ion penetration is effectively prevented. The injectednano-silica can affect an inner pore system and its densification, and then the protective layer for preventing chloride penetration is formed.

Description

technical field [0001] The invention belongs to the technical field of concrete electroosmosis, and in particular relates to a concrete antirust and reinforcement device and method based on electroosmosis technology. Background technique [0002] Concrete is an artificial stone made of raw materials such as cement, water and aggregate (fine aggregate such as sand, coarse aggregate such as pebbles, gravel) and other raw materials, which are poured in human form after mixing, and cured and hardened. Concrete structure refers to the structure mainly made of concrete, including plain concrete structure, reinforced concrete structure and prestressed concrete structure. With the rapid and continuous development of modern concrete technology and my country's economy, concrete is widely used in the construction of modern projects such as ports, dams, highways, bridges, and municipal projects. However, due to the physical or chemical erosion of various environmental conditions, such...
