Anti-corrosion concrete component and pouring method thereof

Abstract

The invention discloses a novel anti-corrosion concrete component which comprises base layer concrete, a lower high-performance fiber net and upper layer concrete. The upper layer concrete is permeated into grids of the lower high-performance fiber net which is located at the positive bending moment concentration position of the bottom of the anti-corrosion concrete component. The anti-corrosion concrete component contains corrosive sea water and / or sea sand so that steel bar pouring cannot be adopted; and the main stressed position of a beam or a plate needs to resist positive bending moment of a mid-span beam or plate at the lower layer and negative bending moment of the mid-span beam or plate at the upper layer, chloridions in the sea water and the sea sand cannot corrode high-performance fibers, the lower high-performance fiber net can resist tension formed by the positive bending moment, and an upper high-performance fiber net can resist tension formed by the negative bending moment so that after bending properties of the two positions are well achieved, the strength problem after the beam or plate has no steel bar can be solved, and the problem of sea water and sea sand resource utilization of coastal area and marine concrete structures can be solved.

Description

technical field [0001] The invention relates to a novel corrosion-resistant concrete component. The invention also relates to a method of pouring corrosion-resistant concrete elements. Background technique [0002] In the construction industry, various beams and slabs of buildings require a large amount of sand and water. Due to the vigorous construction in my country in recent years, the supply of sand and water resources has gradually become tight. How to find alternatives with sufficient supply sources is urgent . The supply of sea sand and sea water is sufficient, but the chloride ions in sea sand and sea water can easily corrode steel bars, resulting in a decrease in the bending and shearing properties of concrete. How to use sea sand and seawater in buildings without compromising performance has become a topic. Contents of the invention [0003] In view of the lack of background technology, the technical problem to be solved by the present invention is to provide a...
