Method of improving durability of a building, building, far-infrared radiation therman storage floor heating system, and method of improving soil of building lot.

摘要

A fill layer (34) containing a ceramic/carbon mixture is provided under an entire surface of a floor. A crushed stone layer (36) including the ceramic/carbon mixture is provided on the top surface of the fill layer (34). A concrete layer (38) containing the ceramic/carbon mixture is provided on the top surface of the crushed stone layer (36). A thermally-insulating, moisture-proofing layer (40), which is formed of an extrusion-foamed styrene and a moisture-proofing film is provided on the top surface of the concrete layer (38). A mortar layer (42) including the ceramic/carbon mixture is provided on the thermally-insulating, moisture-proofing layer (40). A hot water pipe (46) or an electric heater is embedded in the mortar layer (42), and a finishing material (45) is laid on the surface of the mortar layer (42). Far-infrared radiation is emitted from the ceramic/carbon mixture, and the heating efficiency can be improved by stored heat.
