Description

Porous concrete is environmentally friendly material that has continuous voids inside to be used widely in various fields. The performance of porous concrete is largely determined by the size and quantity of the internal pores, and pore size is controlled and adjusted by the aggregate grain diameter used as well as the volume of bonding material. However, according to the past papers, most of studies on the porous concrete, the aggregate of the particle size 2-20 mm has been used. Therefore, in this study, to expand the usage of porous concrete, manufacturing method and fundamental properties of porous concrete with small (particle size : 0.6-2.5 mm) to large (particle size : 40-400 mm) size aggregates have been examined. In this report, manufacturing method of large particle size porous concrete and applicability as fishing bank were introduced.
