Abstract
Porous concrete is a concrete with large amount of continuous pores that have been intentionally inserted; it belongs to a completely different category from conventional concrete. Therefore the physical characteristics of porous concrete differ greatly from normal concrete in its properties, such as permeability, water retention, water purification, being a vegetation base, functioning as a habitat for organisms, etc. It is a material that has great potential to be used widely in both civil engineering and architecture in the future. In the present study, a new type of double-layer porous concrete pavement is proposed to provide comfortable circumstances around houses. The pavement consists of the base layer of conventional porous concrete and the surface layer of color small pebbles bound by epoxy resin. A site experiment was carried out in front of the school building of the architectural department in Mie University. It has been confirmed that the proposed pavement method is quite effective to realize a safe and beautiful walking way.
