[Industrial Application Field] The present invention relates to a method for manufacturing a water-permeable body having a water-permeable effect. [Conventional technology] The conventional method is to sieve aggregate such as gravel,
Select particles with approximately constant particle size, mix with cement slag or cement mortar, and pour into formwork.
For example, granules such as coal ash, which is made by adding a binder such as cement to powder such as fly ash and granulating it to an approximately constant particle size, are hardened and cured, and then mixed with cement slag or cement mortar, etc., and molded. The method involved pouring it into a frame and letting it harden. In addition, when forming slag etc. and binding material,
As described in JP-A No. 48-92271 and JP-A No. 51-17206, molding was usually carried out by applying pressure and heating. [Problems to be solved by the invention] However, the products manufactured by the conventional method,
It has a problem of low water permeability, and when used for things like sidewalk boards, it has the disadvantage of poor drainage. In addition, the latter method of making aggregates by hardening and curing granules such as coal ash has the problem of requiring hardening and curing processes in the aggregate manufacturing process, and requires a certain period of time and equipment. Ta. Furthermore, the former method using gravel or the like as aggregate had the problem of being heavy, making it inconvenient for transportation. Also, JP-A-48-92271, or JP-A-51
- In the example described in Publication No. 17206, there is no water permeability effect,
Additionally, pressurization and heating equipment were required. The purpose of this invention was to solve the above problems, and by a simplified process,
It is an object of the present invention to provide a method for producing a water-permeable cured body that is lightweight and has a large water-permeable effect. [Means for Solving the Problems] In order to achieve the above object, the method for producing a water permeable hardened body according to the present invention includes adding a binder to powder such as flyash or slag, or a mixture thereof. The method is characterized in that the granules are granulated, filled into a mold while uncured, and cured without applying pressure or heating. [Function] According to the above configuration, the granulated material filled into the mold before hardening is bonded at the contact areas between the granules due to the action of the binder, but the non-contact areas are bonded between the granules. It hardens while leaving a space. Therefore,
Since this space becomes a water passage, a water-permeable hardened body is formed. [Example] Hereinafter, specific examples of the present invention will be described. Test specimens were specifically manufactured using the A and B formulations shown in Table 1 below.

Three types of granules of mmφ were cast without hardening into a cylindrical mold with a diameter of 10 cm and a height of 20 cm while applying vibration, and then hardened and cured to produce test specimens. These specimens were tested in accordance with JISA1218 (soil permeability test method), and the results shown in Table 2 below were obtained.

As described above, according to the present invention, coal ash can be effectively utilized to produce a lightweight water-permeable hardened body with a large water permeability coefficient from coal ash in one step. Furthermore, the permeable hardened body produced by the present invention can be used as construction materials such as sidewalk boards that allow rainwater to soak into the soil, water supply and drainage filter materials such as drainage basins that filter sewage and seep into the soil, and others. Its uses are extremely wide, including as a garden plant enclosure.
