| 摘要 |
The present invention relates to a method for manufacturing a basal ground material or a substitute for basal ground using waste adsorbents generated from various manufacturing plants or places of business and, more specifically, to a method for manufacturing a basal ground material using waste adsorbents to manufacture the basal ground material which is eco-friendly and excellent in permeability by adding washed sand to recycled aggregate containing waste adsorbents. The method for manufacturing the basal ground material comprises the following steps: injecting and crushing recycled aggregate, waste adsorbents, and general washed sand to be sorted; adjusting the size of a particle of the sorted material; performing primary mulling while putting a firming agent to the material with adjusted particle size; secondarily sorting the mulled material; and performing secondary mulling while putting a neutralizing agent to the secondarily sorted material. The recycled aggregate includes waste molding sand, slag, and ceramic fragments, and the waste adsorbents include anthracite and washed sands. |
