An Experimental Study on the Evaluation of Porous Concrete using Industrial By-products of Planting Factory

산업부산물을 이용한 포러스콘크리트의 식생능력평가에 관한 연구

Porous concrete with a great deal of continuous porosity enables to contain water and to pass air freely through firmly hardened material, and allow necessary nutrients to reach roots of vegetation. Therefore, this paper deals with the voluntary properties and efficiency for planting of plant porous concrete. The results of experiment showed that void volumes were 17% to 31%, and compressive strength ranged between 80kgf/cm$^2$ and 180kgf/cm$^2$ when the ratio of the paste to aggregate was 0.3-0.5 When the aggregate size are 20-30mm, the paste to aggregate ratio is 0.3, and the length of Paranial Ryegress came up as 32cm. Ut supra the efficiency of planting goes through Paranial Ryegrass in result the length of plant are in compliance with void volume and aggregate size.
