ABSTRACT
In this work, to further investigate the vegetation concrete technology for slope protection, a total
of 10 groups mix proportion specimens of porous concrete were designed and constructed. As a result,
the impacts of different parameters include the fly ash and silica fume contents on the mechanical
properties and porosity as well as the pH value of porous concrete were discussed. Meanwhile, ecomodified
soil with resistance to the erosion of rainwater was sprayed on the surface of porous concrete
for the survival of native grass growth. In addition, the growth characteristics of the Festuca arundinacea
schreb (Chinese grass) within eco-modified soil on the surface of porous concrete were observed and
monitored for 8 weeks including the average height, root system development and relative coverage
of grass. The results show that the compressive strength and porosity of porous concrete measured
after 28 days were at least 13Mpa and 21% respectively, indicating the porous concrete is suitable for
the slope protection in practical engineering. Furthermore, the integration of eco-modified soil and
porous concrete was successful, and all grass survived in the eco-modified soil and porous concrete
environment for the duration of the observation period, and the coverage rate of vegetation reached
96% or above. It was also found that the roots system has permeated the pores of porous concrete and
reached the bottom of porous concrete after 8 weeks.
