地質改良固化材於台灣重大工程之應用案例探討柯武德 1 何世盛 2 梁家豪 2 蔡艾欣 1 1正修科技大學土木工程系 2中聯資源股份有限公司 摘要 目前台灣大部分地盤改良工程仍採用普通卜特蘭水泥施作，不但價格昂貴且改良效果不一致。有鑒於此，在台灣開發了新材料「地質改良固化材」，本材料不但具有比傳統普通卜特蘭水泥更為優異的強度、抗酸鹼性及耐久性外，價格也比卜特蘭水泥更具經濟性。 新材料「地質改良固化材」成功的應用於高壓噴射灌漿、預壘樁、植入樁、拌合樁、低壓滲透灌漿、隧道背填灌漿、污泥固化、CLSM 管線回填等工程。本文將介紹採用地質改良固化材之工程案例，並與普通卜特蘭水泥做比較，期待有助於隧道及地下工程界使用固化材時，有另一種選擇。關鍵詞：地質改良固化材、高壓噴射灌漿、背填灌漿CASE STUDY OF APPLICATION OF GEOLOGICAL IMPROVEMENT HARDENER TO PUBLIC WORKS AT TAIWANWu-te Ko 1，Shih-Sheng Ho 2，Chia-Hao Liang 2，I-Shin Tsai 1 1 Cheng Shiu University，Kaohsiung 2 China Hi-Ment Corporation，KaohsiungAbstract The blast furnace slag was recently used to develop new geological improvement hardener (super fine cement) (SFC) for soil improvement purpose at Taiwan. Advantages of the super fine cement include better water-resistant and improved soil strength resulted from a well-graded grain size distribution. Moreover, because the SFC is recycled from the manufacture process of iron, not only the price of the SFC is very compatible with other Portland cement but also recycling slag is a typical case of waste reduction. In this paper, the authors will first present the material properties of the SFC. Three case will then be presented to describe the applications of this new cement at public works. Finally, performance of the SFC would be summarized as conclusions of this paper.Keywords: geological improvement hardener, jumbo-jet special grout method, back-fill1.前言 台灣鋼鐵年產量平均約一千多萬噸，隨後所產生廢棄物也相當可觀，但經由...
