SOLIDIFIED AGENT FOR DEEP CEMENT MIXING METHOD

摘要

The present invention relates to a solidified composition for a deep mixing method. More specifically, the present invention relates to a solidified composition for a deep mixing method, wherein a blast furnace slag fine powder is used as a main ingredient, and sodium silicate promoting the congelation of a solidified material is substituted in combining water and a solidified material in which petro-cokes desulfurized gypsum is compositely utilized as a stimulator so that the strength expression of a blast furnace slag fine powder is promoted and rapid hardening properties are imparted. The solidified composition for a deep mixing method of the present invention includes 20-100 parts by weight of petro-cokes desulfurized gypsum and 50-300 parts by weight of combining water based on 100 parts by weight of a blast furnace fine powder. It is preferable that 10-200 parts by weight of an aluminate-based accelerating agent is further included based on 100 parts by weight of the combining water.
