Problems solved by technology

Most of the guardrails on both sides of pedestrian bridges are made of steel, and the exterior is painted with paint for anti-rust treatment. However, due to the poor durability of the paint, it is easy to fall off due to long-term immersion in water, resulting in large areas of rust around the foot of the bridge column or around the welding seam. If it is not treated in time, severe corrosion will cause the guardrail to break, seriously threatening the safety of pedestrians and vehicles under the bridge.

Abstract

The invention discloses a rustproof and environment-friendly cement-based material as well as a preparation method and application thereof. The rustproof and environment-friendly cement-based materialconsists of sodium carbonate (Na2CO3), calcium hydroxide (Ca(OH)2), sand, slag, a PTB (polytechnisch bedrijf) emulsion and water, wherein the mass percentages of the components are as follows: 1.2-3.2% of Na2CO3, 0.8-2.2% of Ca(OH)2, 31.6-68.2% of sand, 20.2-46.6% of slag, 3.1-5.7% of the PTB emulsion and 6.5-10.7% of water; and the sum of mass percentages of the components is 100%. The rustproofand environment-friendly cement-based material disclosed by the invention has the advantages of being good in environmental protection, good in workability, short in setting time, high in early strength, good in water resistance, excellent in adhesion and durability, and the like, and has a good market application prospect.

Description

technical field [0001] The invention belongs to the field of antirust materials, and in particular relates to an antirust environment-friendly cement-based material and a preparation method thereof. Background technique [0002] In order to avoid conflicts caused by the plane intersection of vehicle flow and human flow, ensure people's safe crossing, increase vehicle speed and reduce traffic accidents. Generally, pedestrian bridges are built in areas with large traffic volume and dense pedestrians, or at intersections, squares and railways. Most of the guardrails on both sides of pedestrian bridges are made of steel, and the exterior is painted with paint for anti-rust treatment. However, due to the poor durability of the paint, it is easy to fall off due to long-term immersion in water, resulting in large areas of rust around the foot of the bridge column or around the welding seam. If it is not treated in time, severe corrosion will cause the guardrail to break, seriously...
