Problems solved by technology

At present, silica fume mainly comes from the by-products of the silicon steel smelting industry. The production cost is high, and the silicon steel smelting industry consumes a lot of energy. It does not meet the concept of energy saving and emission reduction. It has a tendency to be replaced by other materials. Production of silica fume is more uneconomical and not environmentally friendly

Abstract

The invention provides a concrete anti-corrosion etching resisting agent, which comprises concrete anti-corrosion etching resisting agent 45-65wt%, plasticizing agent 0.5-6wt%, light calcinesia magnesia 8-10wt% and the balance sial materials by drying mass.

Description

technical field [0001] The invention relates to a concrete additive, in particular to a concrete anti-corrosion and anti-corrosion agent. Background technique [0002] As the most widely used building material in modern engineering, concrete is widely recognized and has excellent durability. However, in the actual engineering application environment, it is often affected by acid, alkali, and salt, which makes it deepen carbonization, alkali-aggregate reaction, sulfate corrosion, chloride ion penetration, etc. Under these erosions, expansion cracking and loose structure are easy to occur. , Steel corrosion and other phenomena, the concrete structure is damaged, not only affects the safety of the building, but also causes great economic losses and waste of resources. In some places, the cost of maintaining only one project is much higher than that of building a new project, which causes a lot of manpower and material losses, and at the same time brings inconvenience to the no...
