た複合土質安定剤に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a composite soil stabilizer containing lime as a main component, to which an appropriate amount of aluminum hydroxide and fly ash are added depending on the soil quality.
従来の土質安定剤は大別してセメント系と石灰系に分類

団粒化する。That is, in the case of a cement-based soil stabilizer, a glue-like gel-like substance and slaked lime are first produced by the water utilization reaction of the components of the cement. The soil stabilizing effect of cement is mainly due to the adhesion of soil particles by gel-like substances, which is partially accompanied by pozzolanic reactions and carbonation reactions caused by slaked lime. The reaction has the advantage of being fast-acting and having high initial strength, but on the other hand, if the formulation and mixing precision are not properly carried out, local strength unevenness will occur, so strict control is required.
The drawback was that construction management was difficult. In addition, lime-based soil stabilizers exhibit a soil stabilizing effect by reacting with fine clay particles and solidifying through pozzolanic reactions and carbonation reactions. When added to rich soil, Oa O+ H@O→Ca
(OB)* + 15 Due to the reaction of Ka17'noL, it becomes slaked lime, and since slaked lime is a fine particle, it has strong water absorption and promotes a decrease in the water content ratio of soil, and Oa ions generated by dissolving slaked lime are adsorbed on the surface of clay particles. It aggregates and becomes agglomerates.

It is essential to have a clay plug made up of clay, and a portion of the makulime reacts with carbon dioxide gas contained in the soil to form calcium carbonate and solidify.

0In this way, compared to cement, the reaction between lime and soil is slow-acting, slow-acting, and has a low initial strength, but on the other hand, it has the advantage of being easy to manage during construction, especially when quicklime reacts with water and becomes slaked lime. Therefore, it is suitable for stabilizing soil with high water content and viscosity. Therefore, cement-based soil stabilizers are applied to gravelly and sandy soils, while lime-based soil stabilizers are mainly applied to sandy soils and clayey soils with a high fine particle content, as described above.

がある。In addition, there is a need for the development of low-cost soil stabilizers with particular emphasis on economic efficiency, and the development of composite stabilizers in which cement or lime is the main component, with other materials added and mixed, is also underway. . In addition, during construction, both cement and lime are easily dispersed by the fine powder being rolled up, so it is necessary to take measures such as making them into a slurry or adding water to make them moist.

。The present invention uses slaked lime as a basic material, mixes an appropriate amount of aluminum hydroxide with it, and further mixes an appropriate amount of fly ash depending on the soil quality, thereby adding initial strength while retaining the characteristics of lime. We developed a soil stabilizer that strengthens the pozzolanic reaction and is useful for improving soil and ensuring long-term strength. The reasons for incorporating aluminum hydroxide in the present invention are as follows. In other words, the reaction between slaked lime and aluminum hydroxide is that ca(on) dissolves in water and becomes Oa+ and 2 (OH)-, and aluminum hydroxide is highly alkaline due to slaked lime, resulting in aluminic acid AA.

う施工面での有利性もかねそなえている。In the present invention, the reason for mixing 7-) IATSU is that fly ash is an excellent artificial pozzolan, and when used in combination with slaked lime, a large amount of amorphous silica and alumina, which are not hydraulic in themselves but have high reactivity, are mixed. It is effective in increasing the long-term strength of soil and roadbed materials by gradually combining with slaked lime at room temperature to create an insoluble pozzolanic compound. Moreover, it also has the advantage in terms of construction that it prevents dust from scattering at the construction site by retaining moisture.
