Embodiment 1

[0073] Step S1 brine stirring:

[0074] The old brine is transported from the salt lake to the configuration site and mixed with fresh water to form brine with a specific gravity of 1.5.

[0075] Step S2 mixing and stirring:

[0076] a. gravel mixing

[0077] The first crushed stone with a specification of 5-10mm and the second crushed stone with a specification of 10-40mm are put into the loader at a mass ratio of 3:7 for mixing.

[0078] b. Material mixing

[0079] Put the brine formed in step S1 into the loader for mixing with lightly burned powder and medium sand according to the mass ratio of brine, lightly burned powder, medium sand and crushed stone at 1.45:1.2:3.25:4.86 to form brine concrete.

[0080] The above-mentioned brine concrete is used to construct the road according to the construction method of brine concrete.

Embodiment 2

[0082] Embodiment 2 is the same as Embodiment 1, except that in step S2b, a setting retarder is added to the loader as an auxiliary agent, and the mass ratio of the added retarder to lightly burned powder is 0.567:1.2.

Embodiment 3

[0084] Step S1 brine stirring:

[0085] The old brine is transported from the salt lake to the configuration site, and is mixed with fresh water to form brine with a specific gravity of 1.0.

[0086] Step S2 mixing and stirring:

[0087] a. Gravel mixing:

[0088] The first crushed stone with a specification of 5-10mm and the second crushed stone with a specification of 10-40mm are put into the loader at a mass ratio of 3:7 for mixing.

[0089] b. Material mixing:

[0090] Put the brine formed in step S1, lightly burned powder, medium sand, and setting retarder at a mass ratio of 1.4:1.2:3.1:0.5:4.5 for brine, lightly burned powder, medium sand, retarder, and gravel Mix in the machine to form brine concrete.

[0091] The above-mentioned brine concrete is used to construct the road according to the construction method of brine concrete.

Abstract

The invention discloses brine concrete, a preparation method and a construction method. The brine concrete is prepared from brine, light burning powder, medium sand and macadam, wherein the mass radio of the brine to the light burning powder to the medium sand to the macadam is (1.4 to 1.5) to 1.2 to (3.1 to 3.5) to (4.5 to 5.0). The preparation method of the brine concrete comprises the steps of S1 brine mixing and S2 mixed material mixing. The construction method of the brine concrete comprises the steps of S1 roadbed trimming; S2 filling; and S3 joint construction. The raw material of the brine concrete can be obtained by extracting large amount of waste old brine resources in a salt lake, the cost is low, the initial coagulation is quick, and the temperature in a condensation process is relatively high, so that a road can be open as early as possible. The road constructed by the brine concrete provided by the invention is high in strength, high in rigidity, has no corrosion problem and has low maintenance cost at the later stage. Furthermore, the preparation method of the brine concrete provided by the invention is simple and convenient, and the construction quality of the pavement can be effectively ensured by combining the construction method and the brine concrete.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a brine concrete, a production method and a construction method. Background technique [0002] Concrete generally refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate, mixed with water in a certain proportion, and stirred. At present, when the cement concrete produced in the market is used in the salt lake area, based on the characteristics of Portland cement and the special geographical environment of the salt lake, there are a lot of calcium hydroxide and calcium aluminate hydrate in Portland cement, which is easy to cause soft water. , acid and salt corrosion, so the use of Portland cement in the salt lake area is likely to cause high salt corrosion, which reduces the strength of the concrete. Regular maintenance is required in the later work, which increases the cost, and the Portland cement The initial setting...
