Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that anti-corrosion components such as diisopropanolamine and monoethanolamine have a large amount of dissolution in water, and are not easy to be adsorbed on the surface of other components in corrosion-resistant concrete, which is not conducive to the uniformity of anti-corrosion components. Dispersed in corrosion-resistant concrete, it is not conducive to give full play to the anti-corrosion effect of anti-corrosion components

Embodiment 1

[0037] Embodiment 1: a kind of preparation method of high-strength corrosion-resistant concrete for engineering pile, comprising the steps:

[0038] S1 Mixing: Weigh 180kg of coarse aggregate, add 160kg of fine aggregate and 45kg of micro-silica fume, mix evenly to obtain powder. Take 2.8kg of dimethylaminoethanol and 1kg of dodecyl ester, mix well, add 16.8kg of ethanol, stir at room temperature at 200 rpm for 30min, add 22.5kg of attapulgite, continue to stir for 10min, put the material at 50 ℃ After drying for 180min, the modified anticorrosive material was obtained.

[0039] S2 concrete preparation: weigh 40kg of water, stir at a speed of 200 rpm, add 3.5kg of sulfamate water-reducing agent, 3kg of basalt fiber, modified anti-corrosion material and the powder obtained in step S1, stir for 4min, Then 75kg of cement was added, and the stirring was continued for 3 minutes to obtain high-strength corrosion-resistant concrete for engineering piles.

Embodiment 2

[0041] The difference between Example 2 and Example 1 is that Example 2 does not add basalt fibers, and the others are consistent with Example 1.

Embodiment 3

[0043] The difference between Example 3 and Example 1 is that Example 3 replaces the sulfamate water-reducing agent with the polycarboxylate water-reducing agent of equal quality (Sichuan Century Hongguang Technology Co., Ltd., article number 0313), and the others are the same as the implementation. Example 1 remains the same.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a high-strength corrosion-resistant concrete for engineering piles and a preparation method thereof. Background technique [0002] Engineering piles are piles used in engineering and acting as a force in buildings. They are used in engineering entities to bear a certain load, and are mainly used for columns, beams and floors. Concrete piles have the advantages of convenient production, high strength of piles and good corrosion resistance, and are gradually widely used. Concrete piles are generally made of special engineering pile concrete, which has higher requirements for corrosion resistance. [0003] CN105461267A discloses a kind of corrosion-resistant concrete, which is made from the following raw materials in parts by mass: 50-60 parts of cement, 5-9 parts of diisopropanolamine, 7-9 parts of calcium lignosulfonate, and 6-8 parts of calcium nitrate. parts, urea-f...
