AI Technical Summary

Problems solved by technology

However, the existing concrete is a heterogeneous porous material. Under the erosion of carbon dioxide, water, chloride ions, sulfate and other media, it will inevitably be corroded by external factors, and the concrete will be destroyed at an accelerated rate, and the service life will be greatly improved. To solve this problem, the applicant of this patent researched and developed a corrosion-resistant concrete with high corrosion resistance and long service life

Embodiment 1

[0011] Weigh 13 parts of steel slag, 7 parts of crushed stone, 11 parts of rice ash, 22 parts of river sand, 25 parts of VAE emulsion, and 14 parts of hydroxyethyl cellulose ether. 10 parts of vinyl alcohol fibers were mixed for 60 minutes to prepare the corrosion-resistant concrete of the present invention.

Embodiment 2

[0013] Weigh 12~14 parts of steel slag, 6~9 parts of gravel, 9~12 parts of rice ash, 20~24 parts of river sand, 24~26 parts of VAE emulsion, 13~15 parts of hydroxyethyl cellulose ether, at a speed of 500 Stir at rpm for 1 hour to mix evenly, and finally add 10 parts of polyvinyl alcohol fibers and continue mixing for 60 minutes to obtain the corrosion-resistant concrete of the present invention.

Embodiment 3

[0015] The concrete that embodiment 1, 2 is made carries out corrosion resistance test, and the concrete performance that embodiment 1 prepares is better

Abstract

The invention discloses anti-corrosion concrete, which is prepared from the following ingredients of steel slag, detritus, fiber, unhulled rice, river sand, a VAE emulsion and hydroxyethyl ether cellulose. The anti-corrosion concrete has good anti-corrosion performance and can bear heavy pressure and impact.

Description

technical field [0001] The invention relates to the field of concrete, in particular to a 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 obtained by using cement as the cementitious material, sand and stone as the aggregate; mixed with water (may contain admixtures and admixtures) in a certain proportion, and stirred. Concrete, which is widely used in civil engineering. However, the existing concrete is a heterogeneous porous material. Under the erosion of carbon dioxide, water, chloride ions, sulfate and other media, it will inevitably be corroded by external factors, and the concrete will be destroyed at an accelerated rate, and the service life will be greatly improved. To solve this problem, the applicant of this patent researched and developed a corrosion...
