Soil solidifier as well as preparation method and application thereof

Abstract

The invention provides a soil solidifier as well as a preparation method and an application thereof and relates to the technical field of materials. The soil solidifier is prepared from raw materials in percentage by weight as follows: 30%-50% of cement, 25%-45% of fly ash, 10%-25% of anhydrite and 5%-20% of an additive. The soil solidifier can modify sludge and spent clay into materials with high hardness and good water resistance and has better application prospects. The preparation method of the soil solidifier comprises the step of raw material mixing. The method adopts a simple preparation process and is high in controllability, low in preparation cost and suitable for large-scale production.

Description

technical field

[0001] The invention relates to the field of material technology, and in particular to a soil coagulant, its preparation method and application. Background technique

[0002] During the construction of shield tunneling in urban construction and subway construction, a large amount of mud and waste soil will be produced. At present, the treatment of sludge and waste soil basically adopts the method of transporting the produced sludge to the designated waste dump for stacking by the sludge transport unit, and some construction units install equipment on site and add chemical components to the sludge produced After the mud is processed, it is transported and disposed of, and its essential disposal method treats the symptoms rather than the root cause. The accumulation of sludge and waste soil has caused great damage to land resources and ecological environment, so this problem needs to be solved urgently. Contents of the invention
