設される透水性コンクリートブロックに関する。Detailed Description of the Invention (a) Technical Field of the Invention The present invention relates to the control of rainwater runoff (controlling the increase in the total amount of runoff into rivers during rainfall due to urbanization) and the protection of nature such as streets and parks (rainwater infiltration). One of the measures to protect the natural environment, such as securing ground water and promoting greening, and 1 and 7 relates to permeable concrete blocks laid on roads, squares, etc.

ンクリートブロックがみられる。(b) Conventional technology and problems There are still only a few examples of permeable pavement used to control rainwater runoff and protect the nature of streets, parks, etc., as described above.
For example, there is a water-permeable concrete block described in Japanese Patent Publication No. 57-34238.

This indicates the degree to which the sand grains are aligned, and the larger the number, the greater the irregularity in root nodule diameter.)

性の拡大を図ることにある。(0) Purpose of the Invention The present invention aims to form continuous voids with extremely excellent water permeability by making the grain size of the fine aggregate in the cement composition, which forms the surface layer, approximately uniform. The aim is to improve both the water permeability and aesthetics of a concrete block, and expand its versatility.

In addition to forming excellent continuous voids, this stone is also aesthetically improved compared to stones with a mixture of grain sizes of varying sizes.

）。(2) When a coloring agent is mixed into the cement composition of the surface layer, the appearance can be further enhanced. (3) The surface layer acts as a filter, and the large particle size aggregate, cement and water are mixed together. Compared to the 4-layer water-based concrete block, which has a single-layer structure, it is easier to clean it to remove the blockage.
