In the above washing-out finish, a curing retarder is generally sprayed on the surface of the molded body immediately after the molding of the water-permeable concrete, and a portion other than the surface of the water-permeable concrete develops a certain degree of strength, and Before the surface part hardens, the paste or mortar on the surface part is removed using high-pressure water to wash out the aggregate, which is troublesome. Further, in the above-mentioned wash-out finish, it was necessary to treat the wastewater generated by the wash-out finish. for that reason,
There has been a demand for a surface treatment method for water-permeable concrete, which is easy and can remove the paste or mortar covering the aggregate on the surface of the water-permeable concrete to expose the aggregate on the surface without drainage treatment.

Brushes used for brushing the surface of the hardened water-permeable concrete include metal brushes (wire brushes, etc.) and scrubbing brushes. In the present invention, it is preferable that the surface of the water-permeable concrete be brushed 8 to 48 hours after the water-permeable concrete is molded. If the brushing of the surface of the water-permeable concrete is performed 8 hours before the molding, the paste or mortar covering the aggregate is still soft, and it is difficult to remove the paste or mortar, It is not preferable because it becomes difficult to expose it to the surface. On the other hand, when the brushing of the surface of the water-permeable concrete is performed 48 hours after the molding, the paste or mortar covering the aggregate becomes hard and it is not preferable because it takes time to remove the paste or mortar.

In the present invention, the depth of brushing on the surface of the water-permeable concrete is preferably 1 to 3 mm. If the depth of brushing is less than 1 mm, a part of the aggregate on the surface of the water-permeable concrete is covered with paste or mortar, making it difficult to produce a natural color even if seed stones are used. Not preferable. On the other hand, if the depth of brushing exceeds 3 mm, the aggregate on the surface portion of the water-permeable concrete tends to peel off, which is not preferable.

2. Molding of water-permeable concrete specimen Using the above materials, the water-permeable concrete for the base layer, which was kneaded with the composition shown in Table 1, was put into a 10 × 20 × 6 cm formwork so as to have a thickness of 5 cm. Then, the water-permeable concrete for the surface layer, which was kneaded with the composition shown in Table 1, was added so that the thickness would be 1 cm, and the main vibration time of the concrete block molding machine for immediate removal (manufactured by Goyo Koki Co., Ltd.) was set to 5 seconds. Then, vibration pressure molding was performed. After molding, the composition was immediately removed, and a setting retarder diluted 3 times with water was sprinkled on the surface so that each block had a size of 5 to 6 cm 3, and then cured in air at 20 ° C.
