Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a porous concrete molding for planting with an alkali ingredient adverse to growing of plants neutralized, having very high coefficient of permeability, and compression strength usable for regular structural member and pavement member. SOLUTION: The porous concrete molding for planting is a hardened body of a hydraulic composition composed of cement, rough aggregate, water, and a dispersant, wherein, an alkali ingredient is neutralized by carbonization with carbon dioxide, porosity is >=26%, coefficient of permiability is >=2.0 cm/s, compression strength is >=30 N/mm . The method for manufacturing the same is that the hydraulic composition containing cement, aggregate, water, and a dispersant is kneaded in a mixer, subjected to press and vibration forming, thereafter, cured with carbon dioxide gas.
