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 wear-resistant concrete. The wear-resistant concrete is prepared from, by weight, 100 parts of modified epoxide resin, 6-8 parts of ethidene diamine, 15-20 parts of isobutanol, 8-10 parts of dibutyl phthalate, 250-300 parts of ceramsite, 200-250 parts of gravel, 1-2 parts of fluororubber, 0.5-0.7 part of polyurethane fiber and 150-170 parts of cement. The wear-resistant concrete is good in corrosion resistance, high in corrosion resistance and good in mechanical strength.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to an anti-corrosion 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 an anti-corrosion concrete, which has good corrosion resistance, high wear resistance and good mechanical strength. [0004] A kind of anti-corrosion concrete that the present invention proposes, its raw material comprises ...
