BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-strength permeable concrete and a method for producing the same, and more particularly, to sufficiently kneading the existing construction equipment without using any special equipment. The present invention relates to a high-strength water-permeable concrete capable of providing sufficient strength and durability as a result, and a method for producing the same. In the present invention, even if the coarse grain ratio and the sphere ratio of the coarse aggregate are extremely different, the fine aggregate ratio is changed and sufficient strength and water permeability are obtained within a short kneading time only by using a specific admixture. A high-strength permeable concrete having properties can be manufactured.

2. Description of the Related Art Hitherto, it has been difficult to produce permeable concrete. Further, even if manufactured, there is a problem that the strength is low and the durability is poor. Therefore, for example, permeable concrete for use on roads has not yet been put to practical use. As for lightweight concrete, for example, the water-cement ratio is 28 to 37%, and the cement is 75 to 10%.
Japanese Patent Application No. 63-27 proposes a lightweight lightweight concrete having 0 parts and a fine aggregate ratio of 4 to 9% (volume ratio).
No. 311). In this prior art, since the main purpose is to reduce the weight, no consideration is given to water permeability.
