Several factors such as properties, dimensional stability, high strength properties, and water resistance are required as material properties to be provided, but research on material development has been vigorously conducted, and many technologies have already been disclosed. I have. These include those in which a setting regulator (material) is added to cement or a rapidly hardening hydraulic composition to control the setting / hardening speed and flowability, and further include a fluidizing agent, a thickener, a defoaming agent, Although it is a complex composition to which a plurality of admixtures such as emulsions are added, some of them have excellent properties as a material.

Conventionally, there has been a method in which kneading water is mixed to form a slurry in advance, and the slurry is transported to a construction site by a ready-mixed concrete car to perform construction. The method (1) has an advantage that it can be prepared according to the pot life, but it is difficult to prepare a large amount of slurry at a time, so it takes labor and time to prepare a required amount of slurry. However, the self-leveling material has a disadvantage that the merit of labor saving originally intended is reduced.

However, since the transport distance changes for each property and the time required for transport varies depending on the traffic conditions, it is difficult to supply self-leveling materials with the same characteristics with the fluidity changing over time. There was a drawback that it could not be practically applied to those with a short working time. As a solution to this drawback, a method of adding a fluidizing agent or retarder to prevent the deterioration of fluidity according to the required transport time or adding water on site may be adopted. Is inevitable and not preferable. In addition, the surplus slurry material after construction has to be discarded because it is not suitable for use in other places due to its properties, and it is not only economically disadvantageous,
There was a problem with the disposal method of waste materials.

いる。DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention employs a method of preparing a slurry at a construction site. This method of preparing a slurry at a construction site is a preferable method for the construction of a self-leveling material that is sensitive to changes over time in properties, and in a self-flowing hydraulic composition having an ultra-rapid setting time of 3 hours or less. Although it is an indispensable construction method, as described above, the method that has been conventionally implemented for small-scale ordinary concrete construction has a problem in that the construction efficiency is low, and it is difficult to respond when the scale is large. I was holding it.
In the present invention, this problem is solved by adopting a continuous kneading method for mixing the self-flowing hydraulic composition powder with water.

有するスラリーの連続的な供給が可能となる。In the continuous kneading method, a kneading mixer equipped with a powder supply feeder capable of continuously supplying the self-flowing hydraulic composition powder and a water supply device with a water meter is used. This mixer has been developed for preparing a self-leveling material slurry which is desirably prepared on site due to its characteristics. Of course, it can also be used for preparing ordinary concrete slurry. By controlling the powder supply feeder and the water meter mounted on the kneader, kneading can be performed with the water / powder ratio kept at a substantially constant value, and continuous supply of slurry having a constant flow value can be achieved. It becomes possible.

状態が悪くなることがしばしば起こるからである。In the kneading, a slurry having a flow value of 190 to 250 mm is preferably used. When the flow value is smaller than 190 mm, the self-fluidity is not sufficient, and a surface treatment with a register mark or a trowel is required. On the other hand, when the slurry has a flow value larger than 250 mm, the surface state of the cured product often deteriorates due to material separation.

It is preferable to use a pump having a discharge rate of 2 m 3 / hr or more as the slurry transport pump, and it is preferable to use a hopper equipped with a stirring / convection blade.

It is better to apply the method of the present invention. In particular, setting time 3
In the case of a super-hardening self-flowing hydraulic composition that can be opened early within a short period of time, a large-area construction can be performed only by the construction method of the present invention.

In addition, since the continuous kneading method is employed, slurry preparation at a practical speed becomes possible, and it is possible to sufficiently cope with casting into a large area. Furthermore, since the slurry can be prepared according to the required amount, there is an advantage that no extra slurry is generated which must be discarded. Hereinafter, the present invention will be described in more detail with reference to specific examples.
