Problems solved by technology

However, concrete is essentially a heterogeneous porous material. Under the erosion of carbon dioxide, water, chloride ions and other media, it will inevitably be corroded by external factors, which will reduce the durability and strength of the concrete structure. The building is partially damaged and the service life is greatly shortened

Abstract

The invention discloses high-strength corrosion-resistant concrete and relates to the technical field of concrete. The high-strength corrosion-resistant concrete is prepared from the following ingredients: 8-hydroxyquinoline sulfate modified fly ash, biomass cornstalk carbon powder, Portland cement, yellow sand, isobutyl triethoxysilane, basalt fiber, monoalkyloxy titanate, hydroxyethyl cellulose,a polycarboxylate superplasticizer and water. by the collaborative effect of 8-hydroxyquinoline sulfate modified fly ash and biomass cornstalk carbon powder, particle deflocculant diffusion can be achieved, concrete workability is improved, viscosity and pouring compactness are increased, densification of initial structure of concrete is realized, and corrosion resistance and durability of the concrete are effectively enhanced.

Description

technical field [0001] The invention belongs to the technical field of concrete, and in particular relates to high-strength corrosion-resistant concrete. Background technique [0002] Concrete is a general term for engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete that uses cement as the cementitious material, sand and stone as the aggregate; it is mixed with water in a certain proportion and stirred. It is also called ordinary concrete, which is widely used in civil engineering. Concrete has been widely used in the field of civil engineering because of its excellent physical and mechanical properties, and it is currently the most widely used building material. However, concrete is essentially a heterogeneous porous material. Under the erosion of carbon dioxide, water, chloride ions and other media, it will inevitably be corroded by external factors, wh...
