Potential for planting base of highly alkaline soils generated from construction by mixing neutralizing agents

In late years, quantity of construction by-products tends to increase in our country. Therefore, dumping restraint of construction by-products and promote those recycling are the most critical issue from a viewpoint of establishing the recycling society. In the other hand, soils generated from construction generally show strong alkalinity because cements are mixed. Thus, the cost at the time of the disposal of soils generated from construction becomes expensive, and it is thought that it has a great influence on environment when the soils is disposed by no improvement. However, it is the present conditions that technique in consideration of the influence on environment with non-appropriate processing is not established. Therefore, a vegetation is applied for an index indicating a recycling potential of soils generated from construction. This paper is inspected experimentally to the potential of soils generated from construction as a planting base by mixing neutralizing agents. It was realized that the soils generated from construction had vegetation by mixing neutralizing agents.
