Problems solved by technology

[0002] In some corrosive environments along the coast, traditional concrete itself does not have the effect of anti-corrosion, and the steel bars in the reinforced concrete used are often corroded by corrosive media, resulting in damage to the reinforced concrete structure and causing huge losses; In some environments with large radiation, strong reinforced concrete and extremely thick walls are often used, which is very costly

Embodiment Construction

[0013] It is prepared from raw materials with the following weight fraction ratio: Portland cement: fly ash: water: water reducing agent: rust inhibitor: fine aggregate: coarse aggregate: boron-containing filler: metal filler = 0.65~0.75: 0.35~0.25:0.52~0.72:0.007~0.012:0.014~0.016:2.1~3.6:2.5~4.4:0.01~0.015:0.85~0.89, the fine aggregate is sand with a particle size of 0.15~4.75mm, the The coarse aggregate is crushed stone with a particle size of 4.75-19.00 mm, the boron-containing filler is colemanite with a particle size of 1.0 mm, and the metal filler is iron or steel particles with a particle size of 7 mm.

[0014] A preparation method of anti-radiation and anti-corrosion concrete is characterized in that it is prepared by the following process steps according to the raw materials:

[0015] (1) Add the formula amount of coarse and fine aggregates into the mixer, add 35% of the water, stir for 30~60s to make the aggregate absorb water to saturation;

[0016] (2) Add the am...

Abstract

The invention relates to constructional concrete, specifically to anti-radiation anticorrosion concrete and its preparation method. The anti-radiation anticorrosion concrete contains portland cement, fly ash, a boron-containing filler, a metal filler, a water reducer, an anti-rust agent, a fine aggregate and a crude aggregate. In comparison with the prior art, with the addition of the boron-containing filler, the metal filler, the water reducer and the anti-rust agent in the concrete, the water reducer has hydrophobicity and can effectively endow the concrete with an anticorrosion effect; the anti-rust agent is combined with the concrete to form a layer of molecules on the surface of a steel bar for chemical protection so as to inhibit the corrosion of the steel bar's cathode and anode and effectively prevent the corrosion of the steel bar; and with the combination of the boron-containing filler and the metal material, the concrete has a good and effective radiation-shielding effect. By the adoption of the preparation method, the concrete is endowed with anticorrosion and anti-radiation effects and the quality of the concrete is raised.

Description

technical field [0001] The invention relates to concrete for construction, in particular to anti-radiation and anti-corrosion concrete and a preparation method thereof. Background technique [0002] In some corrosive environments along the coast, traditional concrete itself does not have the effect of anti-corrosion, and the steel bars in the reinforced concrete used are often corroded by corrosive media, resulting in damage to the reinforced concrete structure and causing huge losses; In some environments with large radiation, strong reinforced concrete and extremely thick walls are often used, which is very costly. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention prepares a kind of anti-corrosion and anti-radiation concrete, and improves the performance of the concrete itself. [0004] In order to achieve the above purpose, a kind of anti-radiation and anti-corrosion concrete is designed, including Portland cement,...
