Concrete corrosion inhibitor and premixed concrete using same

Abstract

The invention relates to the technical field of concrete additives, in particular to a concrete corrosion inhibitor and premixed concrete using the corrosion inhibitor, and the concrete corrosion inhibitor comprises the following components in parts by weight: 0.2-0.6 part of sodium molybdate, 10-16 parts of benzotriazole, 4-8 parts of an adhesive, 12-18 parts of octyl triethoxysilane and 30-40 parts of water. The concrete corrosion inhibitor provided by the invention can reduce the defect of soil pollution caused by the corrosion inhibitor while ensuring the corrosion inhibition performance of the corrosion inhibitor.

Description

technical field [0001] The application relates to the technical field of concrete additives, in particular to a concrete rust inhibitor and ready-mixed concrete using the rust inhibitor. Background technique [0002] Concrete performance degradation and even failure damage caused by corrosion of steel bars in chloride salt environment has become a major problem that is widely concerned and increasingly prominent all over the world. The damage caused by corrosion of steel bars in coastal projects in my country is also very serious. [0003] The ways to improve the durability of concrete structures under chloride salt environment include basic measures and additional measures. The basic measures are to use high-performance concrete and increase the thickness of the protective layer. Coating and steel bar rust inhibitor, etc.; among them: steel bar rust inhibitor is one of the most standardized additional measures. However, the existing rust inhibitors contain heavy metal nitr...

AI Technical Summary

Problems solved by technology

However, the existing rust inhibitors contain heavy metal nitrite, which has the disadvantage of easily polluting the soil.
