中文摘要 | 本文探討皂土穩定液及高聚物穩定液之基本性質。分別說明皂土穩定液之礦物組 成、水化作用及漿液之穩定狀態,並以試驗證明粘土泥漿對鹽含量之敏感性及各類高分子 聚合物之起源及化學組成,高聚物溶液與粘土顆粒間之吸附作用及絮凝效果。文內並探討 兩類穩定液在工程應用上之護壁效果及懸浮能力差異,並以工地試驗證明皂土穩定液在澆 置混凝土時之化學性劣化及介紹高聚物添加劑之作用。最後建議工程界對高聚物穩定液作 有糸統之後續研究。 |
英文摘要 | This Article introduces the basic properties of bentonite clay shurry and polymer stabilizing fluid. For bentonite clay slurry, its mineralogical structure and composition, clay-eater ineraction and stability of clay suspension are first presented. Results of a few laboratory tests have proved the snesitivity of salt content on stability of a clay slurry. For the discussion of polymer stabilizing fluids, their chemical compositions, solution, adsorition phenomenom with clay colloids and flocculation behaviors are introduced. In engineering aplications, the two types of sabilizing fluid have shown different characteristics in forming "filter cake} and soil cuttings carrying ability. Site evidences are illustrated to indicate deterioration of Nabentonite slurry caused by calcium attack during concreting. The function of various type of polymer additives to bentonite slurry are also inroduced. Finally it is suggested that future researches on the fundamental properties of polymer stabilizing fluid are necessary. |
