開発され使用されている。Highly organic soil such as beet, which is the target soil of the present invention, contains humic acid and the like that retards or inhibits the hydration reaction of the above-mentioned quicklime-based and cement-based solidifying materials. Even when used, the development of strength was poor, and a large amount of solidifying agent was required to be added. Therefore, solidification materials for this soil with high organic matter content have been researched in various fields, and a representative example is the aryne-based calcined material (3CaO3A1m0sCa
A special cement-based assimilated material containing SOa') as its main component has been developed and used.

を起こ一′等の問題がある。However, the Align-based fired product, which is the composition of this special cement-based solidifying material, is synthesized and achieved by high-temperature firing, and it is inevitably an expensive material.
Next, considering the construction aspect, in addition to the normal dry method 1 method, when performing the so-called deep mixed method where the soil depth is deep, and even in surface layer improvement, it is difficult to improve ultra-soft ground. Wet method 1 is often adopted, and
The wet type 1 method is sometimes adopted for the purpose of preventing dust generation in urban areas where there are many residents. In such cases, in order to maintain rapid hardening properties in the presence of water, the Align-based fired product, which is a special cement-based solidifying material composition, undergoes 1- gelation during mixing with the soil; To avoid deterioration of workability or a state where mixing becomes impossible, it is necessary to add a setting retardant, which requires extremely complicated operations such as setting the addition volume, and also causes slurry damage due to mixing errors etc. There are problems such as caking due to caking within the charging device.

Although it is not possible to determine the reason why it exhibits performance equal to or better than that of special Hyment-based solidifying materials, it is difficult to determine why pulverized blast furnace slag of 5000 cya"/g or more has a contact area with water and alkaline stimulants. It is thought that the increase in F speeds up the water utilization reaction, which results in early strength.In addition, the formation of thringite is caused by the presence of sulfate roots and water when using aryne-based calcined products. directly J
In contrast, in the solidification material of the present invention, in the presence of sulfate powder other than gypsum, aluminum source eluted from blast furnace slag, calcila A m supplied from cement, and calcila A m supplied from gypsum are generated in the solidifying material of the present invention. The SO8 source reacts to produce ettringite.
即ち、溶出、反応の２段階にて生成するためと考えられ
る。That is, it is thought that this is because it is produced in two steps: elution and reaction.
