Abstract

This study examined a feasibility to produce lightweight soils for vegetation using aerated concrete. The aerated concrete produced primarily using cement and foam agent was crushed into 1~100 mm particles in accordance with the particle distribution of natural soils. The alkalinity of aerated concrete particles was reduced to near neutral level through the immersion into ammonium dihydrophosphate solution. To examine the applicability of the near-neutralized particles for vegetation soils, electrical conductivity, cation exchange capacity, C/N ratio, and total organic content were measured and compared with the common criteria values recommended in the landscape standard specification. The near-neutralized particles met the standard value for soil acidity and cation exchange capacity but had higher values for electrical conductivity than the standard ranges. Overall, the vegetation soils using neutralized aerated concrete particles require an addition of carbonic or organic fertilizer.
