Description

A new dust scattering prevention material using polyion complex is developed to prevent the diffusion of dust and the scattering of sediment during construction works. The polyion complex is a mixture of two polymers of positive and negative electric charges, respectively. It solidifies soil by the electrostatic action. Indoor tests were conducted to determine the polyion complex component and formulation ratios. Subsequently, dust scattering tests and rainfall durability tests were conducted in the outdoors. Workability was examined by conducting spraying tests and the preparation of polyion complex solution at the site. The experimental results on the durability against rainfall, and the dust suppression effect resulting from the polyion complex are reported. (author)

Abstract (Japanese)

工事中に発生する飛散土砂や粉塵に対して,ポリイオンコンプレックス(以下,PICという)を用いた粉塵飛散防止材を開発した。PICは,正電荷を持つ高分子と負電荷を持つ高分子の混合物であり,電気的作用によって結合し,土壌を固結させる。ここでは,PICの種類や配合,散布量を配合選定試験で選定し,屋外試験において,粉塵飛散抑制効果や降雨耐久性などを調べた。また,試験結果等に基づいて選定した配合について,実規模の作液試験や散布試験を実施し,施工性を検討した。粉塵抑制効果や降雨に対する耐久性が認められたので,その結果について報告する。(著者)
