Abstract

The invention relates to an anti-microbial and anti-corrosion concrete material for marine ecological engineering. The concrete material comprises a concrete base material, a fiber-reinforced lining material and a dispersing agent, wherein the adding mass of the fiber-reinforced lining material is 2-3% of the volume of the concrete base material; the adding mass of the dispersing agent is 0.4-0.6% of the volume of the concrete base material; each one cubic meter of the concrete base material is processed by the following raw materials based on weight: 300-400kg of silicate cement, 600-800kg of desalted sea sand, 800-1,000kg of detritus, 3-5kg of inorganic antibacterial agent, 1.2-4kg of concrete water reducing agent and a proper amount of water. Compared with conventional concrete material, the concrete material disclosed by the invention has the beneficial effects as follows: 1, the desalted sea sand is wide in source, convenient to get, and is wetted or washed by sea water naturally, so that the desalted sea sand has excellent sea water corrosion resistance compared with river sand or other dinas; 2, the fiber-reinforced lining material has high toughness, so that it is equivalent that multiple micro reinforcing ribs are added in the concrete material, and the strength of the concrete material is greatly improved consequently; and 3, the concrete material is excellent in the anti-microbial property, and the service life of the concrete material is greatly prolonged.

Description

technical field [0001] The invention relates to an antibacterial and corrosion-resistant concrete material for marine ecological engineering and a preparation method thereof. Background technique [0002] With the large-scale economic and social construction in our country, especially the construction of island ecological engineering facilities is increasing day by day. At this stage, the facilities processed by ordinary waterproof concrete materials cannot resist the long-term immersion and erosion of seawater, which reduces the service life and use effect of the facilities. Specifically for marine ecological engineering, the existing concrete facilities of marine ecological engineering are easily damaged due to seawater erosion, which affects the effect of ecological construction of marine ecological engineering. In order to improve the service life of marine ecological engineering concrete facilities and effectively resist seawater erosion, a high-performance concrete wit...
