Description

technical field [0001] The invention relates to the field of concrete materials, in particular to a high-strength anti-seepage and anti-corrosion concrete material and a preparation method thereof. Background technique [0002] As an economical and practical structural material, reinforced concrete is widely used in structures such as buildings, bridges, dams and subsea tunnels. Reinforced concrete must face the erosion of the external environment during its use, among which the corrosion of steel bars is the most prominent. Rebar corrosion has become the main factor affecting the durability of reinforced concrete structures in the world today. With the harsh external environment, such as continuous acidified air, high humidity, high salt and high alkali environment, the progress of concrete corrosion will be increased, and chlorine salt corrosion, acid corrosion and pitting corrosion will appear prematurely. These seriously lead to the decline of the durability of the con...

AI Technical Summary

Problems solved by technology

With the harsh external environment, such as continuous acidified air, high humidity, high salt and high alkali environment, the progress of concrete corrosion will be increased, and chlorine salt corrosion, acid corrosion and pitting corrosion will appear prematurely. These seriously lead to the decline of the durability of the concrete structure, and also seriously affect the safety of the project.
