SOLIDIFICATION MATERIAL AND SOLIDIFICATION METHOD OF SOIL
To provide a solidification material capable of imparting an excellent strength development property (for example, the solidification material having a large uniaxial compressive strength of the soil after 7 to 28 days from a time when the solidification material is added and mixed) to the soil, and, a solidification method of the soil using the solidification material.SOLUTION: A solidification material contains a magnesium oxide-containing material and a basic magnesium carbonate represented by a chemical formula: mMgCOMg(OH)nHO (in which m is an integer of 3 to 5 and n is an integer of 3 to 7). In the solidification method of the soil, the solidification material is added to soil and mixed. The content of basic magnesium carbonate in the total amount of the magnesium oxide-containing material and the basic magnesium carbonate is preferably from 0.4 to 18.0% by mass.SELECTED DRAWING: None
【課題】土壌に対して優れた強度発現性（例えば、固化材を添加し混合した時から７〜２８日後の土壌の一軸圧縮強さが大きいこと）を与えることのできる固化材、及び、該固化材を用いた土壌の固化処理方法を提供する。【解決手段】酸化マグネシウム含有物質と化学式：ｍＭｇＣＯ３・Ｍｇ（ＯＨ）２・ｎＨ２Ｏ（化学式中、ｍは３〜５の整数であり、ｎは３〜７の整数である。）で表される塩基性炭酸マグネシウムを含む固化材。該固化材を、土壌に添加し、混合する土壌の固化処理方法。酸化マグネシウム含有物質と塩基性炭酸マグネシウムの合計量中の、塩基性炭酸マグネシウムの含有率は、好ましくは０．４〜１８．０質量％である。【選択図】なし
