STRENGTH MANAGEMENT METHOD OF SLURRY SOLIDIFIED BODY
PROBLEM TO BE SOLVED: To provide a strength management method of a slurry solidified body capable of controlling uniaxial compressive strength developed in the slurry solidified body built in an underground hole so as to be within a certain range including a target compressive strength by accurately grasping a change in properties of stable liquid filled in the underground hole.SOLUTION: A strength management method of a slurry solidified body constructed by solidifying stable liquid filled in an underground hole at an original position includes the steps of measuring a methylene blue adsorption amount after taking a sample from a stable liquid that fills the underground hole and determining a compounding amount of a cementitious hardener to be added so as to solidify the stable liquid on the basis of the measured methylene blue adsorption amount and target compressive strength required for the slurry solidified body.SELECTED DRAWING: Figure 5
【課題】、地中孔に満たされた安定液の性状の変化を的確に捉えて、地中孔に構築する泥水固化体に発現する一軸圧縮強度を、目標圧縮強度を含む一定の範囲内に収めるよう制御することの可能な、泥水固化体の強度管理方法を提供する。【解決手段】地中孔に満たされた安定液を原位置にて固化することにより構築される泥水固化体の強度管理方法であって、地中孔を満たす安定液からサンプルを採取し、メチレンブルー吸着量を測定する工程と、測定したメチレンブルー吸着量と泥水固化体に要求される目標圧縮強度とに基づいて、安定液を固化するべく添加するセメント系硬化材の配合量を決定する工程と、を備える。【選択図】図5
