Title: High strength porous concrete structure and method of manufacturing the high strength porous concrete structure

Abstract: This invention is intended to provide a high strength porous concrete structure which is preferably applied to a water permeable pavement, a draining pavement, a sound insulating board, a sound-proofing barrier, a sound absorbing block for acoustic, a block for plants, a riverbed block, a water purifying matrix, a gas absorbing matrix, a decorative board for building, a fish reef, a block for fish reef or a block for breeding algae and to provide a method of manufacturing the high strength porous concrete structure. The high strength porous concrete structure 1 having an arrangement in which a plurality of lumps 2 whose configuration is rough aggregates are integrally formed with the same concrete tissue and a gap 3 formed between the lumps 2 is through to a back side 2a of the lump 2 is manufactured by putting a thermoplastic material 8 into contact with a surface of a porous concrete structure 6 using rough aggregates 10 so as to form a form 9 and placing mortar or concrete 13 which does not include rough aggregates into the form 9.
