    • PROBLEM TO BE SOLVED: To provide a method, in the lightweight concrete kneaded with a polylactic acid-based biodegradable foam as a lightweight aggregate, for manufacturing a lightweight concrete consolidated body provided with a suitable environment where biodegradation microorganisms (bacteria) play an active part.
      SOLUTION: The method for manufacturing a lightweight concrete consolidated body, in manufacturing a concrete consolidated body with kneading the main raw materials of a cement, a coarse aggregate, a fine aggregate and water, is primarily characterized in that the lightweight concrete consolidated body is contrived to lighten the concrete consolidated body by kneading as a lightweight coarse aggregate a biodegradable foam that a polylactic acid-based biodegradable foaming resin is being foamed for a given ratio to thereby become a foam and to change a pH value of the concrete into such a suitable pH value of about 8.0-9.0 by the addition of a neutralizer as the biodegradation microorganisms (bacteria) play an active part in, and that a biodegradable foam kneaded as a lightweight coarse aggregate, by way of a decomposition intermediate product from the hydrolysis, finally is provided with the suitable environment where the biodegradation microorganisms (bacteria) play an active part in.
