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 2 a 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 .
