コンクリート素地仕上げの視覚心理学的評価

抄録

Concrete walls or concrete structures are often associated with hardness and coldness. None has verified this idea. First, words and phrases describing concrete walls and structures were collected among students and working people, and analysed. It revealed that the idea is true. Second seventeen architectural concrete specimens of 900 mm square with a variety of surface finishing were made and psychologically measured with eight seven-rated-scales. The finding is that the concrete with smooth surface, such as casted in plywood or metal panels gives people the impression of hardness and coldness, whereas concrete with rough surface the impression of softness and warmness. This concept obtained from the small specimens was proved to be applicable to actual concrete walls and structures with actual size.
