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

The invention provides a special anti-corrosion concrete for buildings, which belongs to the technical field of concrete. It is formed by stirring anti-corrosion concrete gel base material, anti-corrosion concrete base material, anti-corrosion concrete filling base material and water, and in parts by weight: the anti-corrosion concrete gel base material is 95-105 parts, so The anti-corrosion concrete base material is 375-412 parts, the anti-corrosion concrete filling base material is 10-17 parts, and the water is 40-45 parts. A production system for anti-corrosion concrete specially used for buildings, which includes a production frame device, a production device for anti-corrosion concrete gel substrate, a production device for anti-corrosion concrete base material, a production device for anti-corrosion concrete filling base material, and a mixing and stirring device. The invention greatly improves the anti-corrosion performance of the concrete, greatly increases the service life of the building, and the structure of the production system is reasonable, which is beneficial to the continuous processing of the special anti-corrosion concrete for the building, and has a high degree of automation.

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...
