SOIL-IMPROVING MATERIAL AND SOIL-IMPROVING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a soil-improving material which can improve a ground strength and a bearing power by adding to a soft soil, suppress a rise of soil pH due to the addition and prevent an adverse effect to an ecosystem caused by a strong alkaline soil, and to provide a soil-improving method using the same.;SOLUTION: The soil-improving material produced by compounding 50-100 pts.mass activated clay and 50 pts.mass or less hemihydrate gypsum to 100 pts.mass unslaked lime and/or light burnt dolomite is added in an amount of 200 kg or less to 1 m³ soft soil, and blended. Thereby, the soil is solidified, the ground strength and the bearing power are improved, and the pH is suppressed low.;COPYRIGHT: (C)2009,JPO&INPIT
