    上載圧下で養生した安定処理土の一軸圧縮強度は,大気圧下で養生した安定処理土のそれよりも増加する.本論文では,安定処理土の微細構造の変化の観点から養生時上載圧による強度増加のメカニズムを解明するため,水銀圧入型ポロシメーターによる間隙径分布の測定および走査型電子顕微鏡による観察を行った.水和物生成量の目安として圧密養生に伴う含水比変化量を取り上げ,これとセメント添加量,養生時間の関係について検討した …

  • Small deformation characteristic of cement stabilized soil cured under overburden pressure

    Kawahara Yoko , Suzuki Motoyuki , Yamamoto Tetsuro , Hiraoka Masaki

    従来の圧密養生装置よりも小型化した圧密養生装置を開発し,セメント系固化材で安定処理したカオリン粘土を上載圧下で養生した.処理土供試体の各種変形係数を求めるために,LDT(局所軸ひずみ圧縮測定装置)を用いて一軸圧縮試験を行った.供試体の養生時の上載圧を4通りとし,養生日数および安定材添加量をそれぞれ変化させた.その結果,一軸圧縮強度が養生時上載圧の増加に伴い増加するのと同様に,1/2強度割線変形係数 …

  • Strength increase characteristics of cement-stabilized unusual soils cured under overburden pressure

    Kawahara Yoko , Fujimoto Tetsuo , Suzuki Motoyuki , Yamamoto Tetsuro , Okabayasi Shigeo

    Unconfined compression tests were performed on cement-stabilized unusual soils cured under several overburden pressures. The test results showed that the unconfined compression strength of the soils l …
