Abstract

The present study was to examine the influence of porosity and moisture content on the water permeability, strength and plant-growth characteristics of porous concrete. The result of the experiment verified that the coefficient of permeability of porous concrete with porosity between $30\%\;and\;36\%$ increased by 2cm/sec and the compressive strength decreased 1MPa at every $3\%$ increase of porosity. In addition, the plant growth of porous concrete showed 5cm at $36\%$ porosity and 2.5cm at $30\%$ porosity respectively. Thus, the higher the porosity, the more the plant grew. When $2\%$ moisture content was used in porous concrete with the same porosity, the plant growth was accelerated two times faster than the case without it.
