An object of the present invention is to provide a water-retentive porous concrete molded article which has both high water permeability and high water retentivity, has high strength, and can suppress a heat island phenomenon in an urban area, and a method for producing the same. I do. A water-retentive porous concrete compact is constituted so that a crushed product of a wood material and a hardened cement is contained as an aggregate of the porous concrete. 30 to 200 parts by weight of the crushed cement hardened material, 0 to 200 parts by weight of the aggregate and / or admixture, and 10 to 30 parts by weight of water are mixed and kneaded. It is configured to be driven into a frame, immediately removed from the mold, molded, and then cured. [Selection diagram] None |
