TACTILE DRYNESS OF BUILDING MATERIALS

This paper explains the practical method of scaling the dryness of building materials, describes the test results of various types of materials and discusses the relations of tactile dryness of materials to the roughness and warmness. The tactile dryness of materials can be obtained by the equation below : D=0.4+0.6W where D : Tactile dryness value R : Tactile roughness value W : Tactile warmth value
