    • PURPOSE: A solidifying composition for deep soil stabilization including a large amount of non-sintering binder and a deep cement mixing method using the same are provided to reduce environmental problems related to cementitious binder, to stabilize the effect of improving soft ground, and to facilitate application. CONSTITUTION: A solidifying composition for deep soil stabilization including a large amount of non-sintering binder comprises 35 to 45 wt% type 1 ordinary portland cement with a fineness between 3,000 cm2/g and 4,000 cm2/g; 35 to 50 wt% ground granulated blast-furnace slag which is non-sintering binder, includes less than 7% of unburned carbon, and has a fineness between 4,000 cm2/g and 4,800 cm2/g; 5 to 20 wt% fly ash which is non-sintering binder; and 6 to 12 wt% gypsum composition of two or more kinds selected from among natural anhydrite, synthetic calcium sulfate, and synthetic gypsum which is byproduct of poly naphthalene sulfur formaldehyde condensate. A deep cement mixing method is to solidify soft ground by using the solidifying composition for deep soil stabilization including a large amount of non-sintering binder.
    • 目的:提供一种用于深层土壤稳定化的固体组合物,包括大量非烧结粘合剂和使用其的深度水泥混合方法,以减少与水泥粘合剂相关的环境问题,以稳定改善软土的效果,并促进 应用。 构成:包括大量非烧结粘合剂的用于深层土壤稳定化的固化组合物包含35至45重量%的细度为3,000cm 2 / g至4,000cm 2 / g的普通硅酸盐水泥, 35〜50重量%的非烧结粘合剂的磨碎的高炉渣包含小于7%的未燃烧碳,并且具有4,000cm 2 / g至4,800cm 2 / g的细度; 5〜20重量%的飞灰,其为非烧结粘合剂; 和6〜12重量%的选自天然无水石膏,合成硫酸钙和作为聚萘硫甲醛缩合物的副产物的合成石膏中的两种或更多种的石膏组合物。 深水泥混合法是通过使用固化组合物固化软土,包括大量非烧结粘合剂进行深层土壤稳定化。
