Anti-corrosion concrete special for building and production system thereof

Abstract

The invention provides an anti-corrosion concrete special for a building, and belongs to the technical field of concrete. The anti-corrosion concrete is prepared by stirring the following components in parts by weight: 95-105 parts of an anti-corrosion concrete gel base material, 375-412 parts of an anti-corrosion concrete base material, 10-17 parts of an anti-corrosion concrete filling base material and 40-45 parts of water. A production system of the anti-corrosion concrete special for a building comprises a production rack device, an anti-corrosion concrete gel base material production device, an anti-corrosion concrete base material production device, an anti-corrosion concrete filling base material production device and a mixing and stirring device. The corrosion resistance of the concrete is greatly improved, the service life of a building is greatly prolonged, the production system is reasonable in structure, continuous processing of the anti-corrosion concrete special for a building is facilitated, and the automation degree is high.

Description

technical field [0001] The invention relates to the technical field of concrete production, in particular to a special anti-corrosion concrete for buildings and a production system thereof. Background technique [0002] Concrete refers to the artificial stone made of cement as the main cementitious material, mixed with water, sand, stones, chemical admixtures and mineral admixtures when necessary, mixed in appropriate proportions, uniformly stirred, compacted and cured. Concrete is mainly divided into two stages and states: the plastic state before setting and hardening, that is, fresh concrete or concrete mixture; the hard state after hardening, that is, hardened concrete or concrete. The concrete strength grade is divided by the standard value of cubic compressive strength, and the concrete strength grade is divided into 14 grades: C15, C20, C25, C30, C35, C40, C45, C50, C55, C60, C65, C70, C75 and C80. [0003] As a traditional construction engineering material, concrete...

Problems solved by technology

Applying anti-corrosion materials on the surface of its structure does have a good anti-corrosion effect, but the life of a layer of anti-corrosion materials on the surface is very short, and it is very easy to age and fall off. After falling off, it loses the protective effect and anti-corrosion effect. Applying anti-corrosion materials on the surface requires an additional construction process, which greatly increases the construction cost

The cathodic protection method is a protective measure for the steel bars in the concrete. The cathodic protection technology is a kind of electrochemical protection technology. Its principle is to apply an external current to the surface of the corroded metal structure, and the protected structure becomes a cathode, thereby making the metal The electron migration of corrosion is inhibited, avoiding or weakening the occurrence of corrosion, but it cannot play the anti-corrosion effect of concrete, and requires an external power supply, great interference to adjacent metal structures, and heavy maintenance and management workload

[0004] At present, many technical solutions have been adopted to improve the compactness of concrete by simply adding water reducers or mineral admixtures to ordinary Portland cement. For example, patent publication number CN101269941A, patent publication number CN11107308A, etc. are all based on the above technologies. has evolved, but its anti-corrosion effect is still not ideal
