Pre-mixed fluidized soil solidifier is a composite material made by blending various discarded construction waste, soil hardening agents, and water in a specific ratio to meet certain performance standards. This technology uses a small amount of inorganic binder to bond soil particles and employs chemical methods (soil solidification additives, etc.) to activate the soil particles, promoting the solidification reaction and enhancing and improving the properties of the hardened soil mass (strength, water stability, impermeability).
This is a green innovative material that can replace traditional concrete, earthen foundation, and crushed stone concrete in certain fields, holding significant social importance for energy saving, emission reduction, and comprehensive utilization of industrial solid waste. The technology can be applied in projects such as solid soil composite foundation, backfill (replacement) foundation, rigid composite piles, and retaining piles for excavation, as well as in the backfilling of trench and subway foundation pits, civil construction foundation pits, roadbed foundation treatment, and construction road surface materials and subgrade materials. It offers advantages such as saving construction materials and investment costs.
Pre-mixed fluidized soil can achieve self-compaction pouring, eliminating the need for vibration or requiring only minimal vibration, making construction simple and significantly reducing the use of labor and machinery. This offers a notable economic advantage in the future labor-constrained construction market. Compared to concrete, pre-mixed solidified soil is a system with high inclusiveness and redundancy, serving as a supplement to concrete in terms of product performance. It does not compete with concrete for bulk raw materials: it does not require sand and stone, cement, and can utilize various solid or liquid waste materials that are difficult for cement concrete to utilize. Therefore, pre-mixed solidified soil is a green building material that can synergistically dispose of multiple types of waste. Moreover, centered around pre-mixed solidified soil, a green industrial chain can be formed with upstream and downstream linkage, synergistically disposing of large quantities of low-quality solid waste such as construction debris, industrial solid waste, and urban sludge, which are urgently needed to be processed in cities. This provides a new solution for "waste-free cities."
