Problems solved by technology

[0003] The concrete foundation has been in such an environment with high chloride ions and sulfate ions for a long time, and the chloride ions will corrode the concrete, causing corrosion of the steel bars, causing early damage to the structure, losing the durability of the structure, and causing cracks, damage, and falling off of the concrete structure It seriously affects the normal use of concrete structures and reduces the actual service life of the project.

Abstract

The invention relates to the technical field of concrete, in particular to a kind of anti-corrosion and anti-rust concrete, comprising the following components in parts by weight: 300-420 parts of cement, 680-730 parts of sand, 980-1200 parts of stones, and 35-50 parts of fly ash , 35-50 parts of mineral powder, 8-15 parts of pumping agent, 8-15 parts of concrete preservative, 8-15 parts of rust inhibitor and 150-200 parts of water; Anti-rust performance; the invention also provides the application of the anti-corrosion and anti-rust concrete in cast-in-place piles.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to an anti-corrosion and anti-rust concrete and its application. Background technique [0002] For marine buildings, sea sand buildings and buildings in saline-alkali areas, coastal areas or surrounding environments contain a large amount of chloride ions and sulfate ions, which are easy to cause corrosion effects on steel bars and concrete, reduce the alkalinity of concrete, and destroy the passivation film on the surface of steel bars , causing corrosion and expansion of steel bars, further leading to cracking and spalling of the concrete protective layer, and the continuous deterioration of the structural function and mechanical properties. For this reason, experts at home and abroad have proposed various measures to improve the anti-corrosion ability of concrete structures, among which adding anti-corrosion agents to concrete is an effective measure that is economical, practica...
