Fiiling of Voids in Porous Concrete with using Earth Materials

Porous concrete is one of concrete with high voids generally is utilized in pavement. In field of maintenance and repair of this type of concrete there is not sufficient information and methodology. For protection of porous concrete as a best method in flood management, this type of pavement should be extended and blocked porous have to improve. In this research, voids in porous concrete is filled by materials such as soil, sand and volcanic sand. Until, with stable compressive strength permeability protected. Results of present study showed that overall with filling voids in porous concrete permeability decreased. When, voids filled by sand, maximum horizontal permeability with 0.38 cm/sec value is made. In contrast, while voids filled by volcanic sand, maximum vertical permeability with 0.33 cm/sec is created. In the other side, maximum compressive strength in specimen with volcanic sand with 5.71 MPa observed. Therefore, it can be explained that, porous concrete useable in shoulder of road, parking, parks and roads with low traffic volume.
