preparation example Construction

[0029]A method for preparing concrete based on wind farm applications, comprising the following steps: 1) taking 5 to 10 parts of air-entraining agent and 10 to 12 parts of halogen agent in 10 parts of clear water in terms of mass parts of raw materials to form a modified Aqueous solution; 2) Add 9-10 parts of pozzolan and 30-37 parts of cement to the modified aqueous solution respectively; 3) Add 35-40 parts of sand and 35-40 parts of gravel with a particle size of 5-10 mm in sequence, and mix well Prepare the slurry; 4) Add 3 to 4 parts of fiber to the slurry; 5) Pouring the slurry into the area to form, ensuring that the fibers are wrapped in the slurry and distributed as symmetrically as possible; 6) Hot air curing; Get concrete.

[0030] Among them, the fiber is plant straw, and the moisture content of the straw is not more than 15%; the air-entraining agent is sodium dodecylbenzenesulfonate, triterpene saponin, polyethylene glycol, nonionic polyacrylamide, sodium stearat...

Embodiment 1

[0041] The present invention optimizes the ratio of air-entraining agent preparation. Because it is beneficial to further reduce the bleeding rate of concrete, and at the same time enhance the compressive strength of concrete, the bleeding rate and compressive strength are used as indicators for determination.

[0042] A method for preparing concrete based on wind farm applications. Each component is made according to the above steps. In order to ensure a single variable, the air-entraining agent is extracted according to the following test in terms of raw material mass parts, and the ratio of other raw materials is as follows: Take 11 parts The halogen agent is placed in 10 parts of clear water to form a modified aqueous solution; after adding 10 parts of pozzolan and 35 parts of cement to the modified aqueous solution, 37 parts of sand and 37 parts of gravel with a particle size of 5 to 10 mm are added in sequence, and mixed to produce The slurry is obtained, and 3 parts of ...

Embodiment 2

[0067] The present invention prefers the ratio of the halogen agent. Because it can make the magnesium cement hardened body produce high strength and has excellent low temperature resistance, it is measured with low temperature resistance and compressive strength as indicators.

[0068] A method for preparing concrete based on the application of wind farms. Each component is produced according to the above steps. In order to ensure a single variable, the halogen agent is extracted according to the following test in terms of raw material mass parts, and the ratio of other raw materials is as follows: Take 7.5 parts of lead The air agent is placed in 10 parts of clear water to form a modified aqueous solution; after adding 10 parts of pozzolan and 35 parts of cement to the modified aqueous solution, 37 parts of sand and 37 parts of gravel with a particle size of 5 to 10 mm are added in sequence, and mixed to produce The slurry is obtained, and 3 parts of fibers are added to the ...

Abstract

The invention discloses a preparation method of concrete based on wind power plant application and a product. The preparation method comprises the following steps: taking 5-10 parts by mass of an air entraining agent and 10-12 parts by mass of a halogen agent, and placing in 10 parts by mass of clear water to form a modified aqueous solution; respectively adding 9-10 parts of volcanic ash and 30-37 parts of cement into the modified aqueous solution, sequentially adding 35-40 parts of sand and 35-40 parts of gravel with the particle size of 5-10mm, mixing to obtain slurry, and adding 3-4 parts of fiber into the slurry; pouring the slurry into the area for forming; performing hot air curing; preparing the concrete; wherein the prepared concrete meets the construction requirements of a wind power plant, the production difficulty is reduced, the quality is stable, and the cost is saved. The invention further provides a concrete plate applied based on the wind power plant, the concrete plate can cover dry mountain roads and mud roads, engineering trucks and transport vehicles can conveniently and rapidly pass through the concrete plate, and the sideslip situation does not occur.
