Effects of two types of activated carbon on the properties of vegetation concrete and Cynodon dactylon growth

Abstract Vegetation concrete is one of the most widely used substrates for slope ecological protection in China. However, there are still some imperfections that are disadvantageous for plant growth, such as high density, low porosity, insufficient nutrient retention ability and so on. In this paper...
