浅瀬石川ダムにおけるテキスタイルフォーム (布張り型枠) 工法の開発

抄録

There is a big demand to develop innovative measures to improve the concrete durability, with increasing social interest in the durability of concrete structure.
“Textile-form method” described hereunder, has been developed with an aim to prevent air bubbles and blow holes, using the complex form consisting of special textile and form with tiny holes providing high air and water permeability.
Through the site experiment for practicability in Aseishi-gawa Dam Project, this method proves several merits such as smoother surface and higher surface strength and compressive strength compared with the conventional methods, and is considered to be applicable in a wide range of concrete construction works.
