Problems solved by technology

Epoxy resin concrete has good corrosion resistance, so it is often used in harsh environments. However, as the use conditions become more and more severe, the corrosion resistance of epoxy resin concrete can no longer meet people's needs, so it is necessary to provide New Corrosion Resistant Concrete

Abstract

The invention discloses anti-corrosion concrete. The anti-corrosion concrete is prepared from, by weight, 100 parts of modified epoxy resin base fluid, 3-5 parts of vinyl triamine, 10-12 parts of trioctyl citrate, 200-280 parts of river sand, 250-300 parts of pebble, 1-2 parts of hydrogenated nitrile rubber powder, 0.4-0.6 part of polypropylene fiber and 140-160 parts of cement. The anti-corrosion concrete is high in corrosion resistance, high temperature resistance, abrasion resistance and mechanical strength.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a corrosion-resistant concrete. Background technique [0002] Concrete is widely used in all walks of life. In some harsh environments, concrete not only needs to have certain mechanical strength, but also has good corrosion resistance. Epoxy resin concrete has good corrosion resistance, so it is often used in harsh environments. However, as the use conditions become more and more severe, the corrosion resistance of epoxy resin concrete can no longer meet people's needs, so it is necessary to provide New corrosion resistant concrete. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a corrosion-resistant concrete, which has good corrosion resistance, high temperature resistance, high wear resistance and high mechanical strength. [0004] A kind of corrosion-resistant concrete that the present inven...
