Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing cement paste, mortar or concrete, and a material container for cement paste, mortar or concrete. The present invention relates to a material capable of easily kneading a solid material and a liquid material without using them.

[0002]

2. Description of the Related Art Cement, mortar and the like (cement paste, mortar or concrete) are produced.
Aggregates, solid materials such as solid admixtures, and water, liquid materials such as liquid admixtures are kneaded, and this kneading is conventionally performed using a power mixer, or a container such as a bucket and a trowel. This is done using tools such as a scoop.

Therefore, after the work, it is necessary to quickly wash the mortar and the like adhering to these instruments and tools, so that it is difficult to secure water for washing and it is difficult to dispose of dirty water after washing. In the place, very troublesome work such as transportation of cleaning water and cleaning sewage was forced, and there was a great inconvenience especially when kneading a small amount of mortar or the like.

[0004]

As described above, conventionally, after the cement paste, the mortar or the concrete was kneaded, it was necessary to wash the equipment and tools used for the kneading to wash away the mortar and the like.

The present invention has been made in view of the above circumstances, and an object thereof is to eliminate the need for cleaning the kneading equipment and tools and to easily manufacture cement paste, mortar or concrete. It is a thing.

[0006]

The method for producing cement paste, mortar or concrete according to the present invention comprises a solid material and a liquid material of cement paste, mortar or concrete in a flexible, hermetically sealed container. The kneading is performed by a force applied from the outside of the container (Claim 1).

The cement paste, mortar or concrete material container of the present invention has at least two independent storage spaces formed inside a flexible container via a partition wall capable of communicating with each other, and at least one storage space is provided. A solid material such as cement paste, mortar or concrete is stored in a sealed state, and a liquid material such as cement paste, mortar or concrete is stored in a sealed state in at least one other storage space (Claim 5).

The container used in the present invention may have a shape such as a bag or a tube, and like the material used for them, a synthetic resin having flexibility, airtightness and liquid tightness, or a synthetic resin such as this. Multi-layered materials such as metal foil and paper can be used. The container is provided with an opening by cutting a part of the container or removing the cap so that the mortar and the like inside can be squeezed and taken out.

In this container, solid materials such as cement paste to be manufactured, cement mixed with mortar or concrete, aggregates, solid admixtures, etc. are stored in a hermetically sealed state, and then water, liquid admixtures, etc. are stored. After injecting the liquid material described in (1) and sealing the container again, the flexibility of the container is used to knead by the force applied from the outside of the container, and the container is shaken or kneaded with a hand or an instrument. By kneading, tapping, shaking, or stepping on the feet, the solid material and the liquid material are kneaded in the container, and the cement paste,
Mortar or concrete can be produced.
In this case, if the liquid material has a blending amount corresponding to the solid material and is stored in a separate container, it is convenient for storage and transportation, and it is not necessary to prepare the blending on site, and the weighing work etc. Is unnecessary.

Further, a plurality of independent storage spaces may be provided in the container, and in this case, the solid material and the liquid material having a composition suitable for the purpose should be stably stored in the separate storage spaces. If necessary, the partition that separates these storage spaces is opened to connect the storage spaces containing the solid material and the liquid material to each other, and the flexibility of the container is used to apply the force from the outside of the container. Solid and liquid materials can be kneaded in a container to produce cement paste, mortar or concrete. Incidentally, even a solid admixture, which may be dissolved in the liquid material from the beginning, may be put in the liquid material. In addition, the plurality of storage spaces may have a structure in which they are continuously arranged vertically or horizontally, a double structure of inside and outside, and the like.

When it is preferable that a plurality of liquid materials are not mixed with each other until the time of use, it is possible to increase the storage space in the container and store them separately. Even when it is preferable not to mix the solid materials of each other until the time of use, it is possible to increase the storage space in the container and store them separately.

The cement paste, mortar or concrete to be produced is not particularly limited. For example, a combination of quick-hardening cement and retarder, a combination of Portland cement or mixed cement and an accelerator, a retarder, etc. may be used. By appropriately selecting and adjusting the pot life, the pot life can be adjusted from several minutes to about 1 hour or more, and thereafter, the pot life can be made to have a characteristic of hardening rapidly, and the efficiency of construction can be improved. Furthermore, if necessary, a water reducing agent,
Admixtures such as thickeners, accelerators, shrinkage reducers and expanders can also be used.

Here, the composition suitable for uniformly kneading the solid material and the liquid material by the force from the outside in the flexible container is relatively liquid material relative to the solid material,
Although the composition has a high fluidity, the composition containing many liquid materials is not preferable because the produced mortar or the like has a large breathing even though the mixing can be easily performed.

Therefore, there is a water reducing agent as a method of reducing the mixing ratio of the liquid material without sacrificing the fluidity, and a thickening agent as a method of reducing the breathing without changing the composition. is there. However, when a thickener is used, its thickening action becomes an obstacle to kneading. Therefore,
When a thickener is used, it is necessary not to exert a thickening effect during kneading, especially at the initial stage. The method is to use a thickener in the form of coarse powder, that is, having relatively large particles and therefore a small surface area per unit amount, to slow down the dissolution rate in water, thereby increasing the thickening effect in the initial stage of kneading. There is a method in which the effect of suppressing the breathing is exerted by virtue of a thickening effect by completely dissolving it in the latter half of kneading without exhibiting the effect. This thickening action also exerts an effect of smoothing the squeezing out when squeezing out the mortar or the like from the container.

[0015]

According to the manufacturing method of the present invention, the solid material such as mortar and the liquid material in the container are kneaded by the force applied from the outside of the container by utilizing the flexibility of the container.
Shake, rub, tap, etc. with your hands or equipment.
Since the mortar and the like are kneaded by shaking or stepping on it with a foot, it is not necessary to bring the mortar and the like into contact with a kneading device or tool.

Since the material container of the present invention can stably store the solid material such as mortar and the liquid material in the separate storage spaces, it is convenient for the storage and transportation of the material. Since mortar and the like can be kneaded in the container, the mortar and the like need not be brought into contact with a kneading device or tool.
