METHOD FOR UTILIZING HARDLY ROTTING PLANT MATERIAL FOR URBAN PLANTING AND WARMING COUNTERMEASURE

摘要

PPROBLEM TO BE SOLVED: To attain an urban planting and a warming countermeasure combining a pH buffer action and a heat-insulating action for preventing a concrete collapse due to acid rain and a weathering of a retaining wall, a block wall, a mortar slope or the like for public facilities centering around the planting of the roof floor section and the wall surface of a concrete structure resulting in a heat-island phenomenon by the unipolar concentration of a population and an urban development, mainly a reinforced concrete-constructed apartment, a mansion, an office building, a commercial building or the like in a large city. PSOLUTION: A substance obtained by changing barks, branches and leaves and pulled stamps of one kind or more in a Japanese cedar, a Japanese cypress, a hiba arborvitae, and eucalyptuses having anti-rotting properties discharged as industrial wastes into fibrous or powdered materials of 5 cm or less is sprayed or scattered and carried out on concrete, a mortar surface and these wall surfaces. The powdered material is mixed with gypsum, plaster, lime and inorganic mud and used. The material is added to an adhesive, paints and a joint filler. PCOPYRIGHT: (C)2005,JPO&NCIPI
