Field of the Invention The present invention relates to a concrete additive on-site mixing and high-speed mixing method and apparatus therefor, and in particular, in the ready-mixed concrete factory, the concrete additive is mixed between the ready-mixed truck and the pump car while transporting the ready-mixed concrete to the construction site by a ready-mixed truck and pumping And a high speed mixing device, and the ready-mixed concrete and the additives discharged from the ready-mixed concrete truck are added to the concrete additives on-site compounding and high-speed mixing device, mixed by stirring with a stirring device, and pulled into the impression discharge unit to feed the pump car. After discharging to a negative portion, by pumping and pouring concrete additives on-site compounding and high-speed mixing method and apparatus for easily adding the necessary amount to the ready-mixed concrete mixture easily and easily.

Conventionally, in the ready-mixed concrete factory, the ready-mixed concrete truck is transported to the construction site by a ready-mixed concrete truck, pumped and pumped, and the additives are added to the ready-mixed truck to add powder or liquid additives. Although the domestic ready-mixed concrete trucks are not provided with mixing or mixing functions, the mixing of materials is virtually impossible. Therefore, there is no actual solution or other solutions that do not achieve the desired characteristics after concrete is poured. These methods are still used in the field, making it difficult to obtain final quality for concrete specific performance.

Therefore, by mixing and pouring additives (mixtures) to give specific performance to concrete in small and medium sized sites in the middle process between ready-mixed trucks and pump cars using high-speed mixing equipment, it is possible to secure the homogeneity of mixing of materials and achieve the required performance perfectly. There is a need for on-site mixing equipment to enable this.

The present invention was devised to solve the above-mentioned problems and defects as described above, the concrete additive site between the ready-mixed truck and pump car while transporting the ready-mixed concrete ready to be transported by the ready-mixed truck in the ready-mixed concrete truck and pumped by a pump car Arrange the compounding and high speed mixing device, and put the ready-mixed concrete and the additive discharged from the ready-mixed concrete truck into the concrete compound on-site compounding and high-speed mixing device, then stir and mix with a stirring device, and raises the impression outlet to raise the pump car. After discharging to the input unit, it is to provide a concrete additive field mixing and high-speed mixing method and apparatus that can be added to the ready-mixed concrete additives simply and easily by pumping and pouring.

In order to achieve the above object, the concrete additive field mixing and high speed mixing method according to the present invention carries the ready-mixed concrete from the ready-mixed concrete plant to the construction site in the ready-mixed concrete truck and supplies it to the pump car, and adds the additive to the input of the ready-mixed concrete truck or pump car. In pouring, mixing and pumping by means of a pump car, a stirring device for inputting and stirring the ready-mixed concrete and the additives discharged from the ready-mixed concrete truck is provided, and the mixed and discharged mixture is discharged on one side of the main wall of the stirring device. After supplying to the concrete additive on-site compounding and high-speed mixing device equipped with an impression discharge unit for pulling up and discharged to the input unit of the mixing unit, the mixture is stirred and mixed with the stirring device, and is drawn up to the impression discharge unit and discharged to the input unit of the pump car, Placing by pumping by pump car The features.

And the concrete additive on-site mixing and high speed mixing device according to the present invention is a stirring device for inputting and stirring the ready-mixed concrete and the additive discharged from the ready-mixed truck carrying the ready-mixed concrete in the ready-mixed concrete factory in the ready-mixed concrete factory, and the main wall of the stirring device On one side is configured to be provided with a discharge discharge for lifting the discharged mixture to be discharged to the input of the pump car.

The stirring device is rotatable via a bearing between a circular stirring barrel capable of height adjustment and movement, a rotating shaft provided at the inner center thereof, a simple rotating stirrer fixed to the rotating shaft, and a support connected to the upper end of the rotating shaft. It is configured to include a dual rotary stirrer coupled to, and a first drive means for rotating the rotary shaft.

The discharge outlet is connected to the discharge pipe formed inclined downward downward so that the mixture is smoothly discharged to the discharge hole formed on one side of the main wall of the circular stirring barrel, and the transfer screw is connected to the discharge pipe inclined outward so as to smoothly discharge the mixture to the discharge pipe and It comprises a second drive means for rotating the conveying screw.

The additives are various functional materials such as concrete waterproofing materials, fluidizing materials, crack reducing materials, crude steel materials, and refills for mixing in ready-mixed concrete.

Here, the remeum is a product developed and distributed by the company's Daehan I Co., Ltd. as a product through the unique reaction mechanism of the remem itself to increase the waterproof structure of the structure itself, and at the same time fly ash as a general concrete mixed material The reaction speed is much faster than that of fine slag powder, so the early strength of concrete can be secured faster. Therefore, high durability concrete structure can be obtained through the effect of air shortening and the improvement of medium and long-term strength. Material separation does not occur and maintains or enhances the advantages of these mixtures because they have excellent affinity with not only chemical admixtures for concrete, but also mixtures such as fly ash and slag fine powder.

In addition, the refilled concrete has a dense structure and a small change in length, so that there is little cracking, the strength is increased, and the watertightness is increased, thereby improving the thermal resistance. In particular, the freeze-thawing resistance is excellent for long-term extension of the concrete structure. It is a very effective product.
