STRENGTH ESTIMATION METHOD OF CEMENT IMPROVEMENT SOIL
To provide a strength estimation method of cement improvement soil capable of simply estimating a strength after the lapse of the specified curing time of a cement improvement soil, at a time before the lapse of the specified curing time.SOLUTION: A water content of a cement improvement soil CS is grasped before the lapse of the specified curing time. Based on a content of a predetermined reference component measured by radiating X-ray R to the cement improvement soil CS by a fluorescent X-ray analyzer 1, a content of a cement-based solidification material in the cement improvement soil CS is grasped. Based on the grasped the water content of the cement improvement soil CS and the grasped content of the cement-based solidification material, a water-cement ratio of the cement improvement soil CS is calculated. Then, based on the calculated water-cement ratio and a relationship data of a strength of the cement improvement soil CS after the lapse of the specified curing time and a water-cement ratio grasped in advance, a strength of the cement improvement soil CS after the lapse of the specified curing time is estimated.SELECTED DRAWING: Figure 2
【課題】セメント改良土の規定の養生期間後の強度を、規定の養生期間が経過する前の時点で簡便に推定できるセメント改良土の強度の推定方法を提供する。【解決手段】規定の養生期間が経過する前にセメント改良土ＣＳの含水率を把握し、セメント改良土ＣＳに蛍光Ｘ線分析装置１によりＸ線Ｒを照射して測定した所定の基準成分の含有率に基づいてセメント改良土ＣＳにおけるセメント系固化材の含有率を把握し、その把握したセメント改良土ＣＳにおける含水率とセメント系固化材の含有率とに基づいてセメント改良土ＣＳの水セメント比を算出する。そして、その算出した水セメント比と、予め把握しておいたセメント改良土ＣＳの規定の養生期間後の強度および水セメント比の関係データと、に基づいて規定の養生期間後のセメント改良土ＣＳの強度を推定する。【選択図】図２
