本発明によれば、下記の優れた効果が期待できる。
本願発明によれば、本願発明は、容易に入手可能で安価な各種石灰やセメントが普通の水に反応して固化するという性質を利用するものであり、水を含浸させたアスベストを含む被覆層に石灰を吹き付けすることによって、石灰が水に反応して固化し、アスベストを含む被覆層が固化した石灰によって被覆される。
また、水をアスベストを含む被覆層に含浸させるため、例えば、水をアスベストを含む被覆層に含浸させる手段に吹き付けという手段を採用する際には、自動・手動問わず何ら変哲の無い普通の吹き付け機器を使用でき、更に、粉状体を吹き付け塗布する際にも同様である。
更に、粉状体とした各種石灰やセメントは、モルタルやコンクリートに比べて、被覆厚さを調整することが容易であるので、被覆層の死荷重の低減が可能である。
したがって、アスベストの飛散防止処理を迅速、且つ安価に行えるアスベストの飛散防止工法を提供できる。
