Abstract
Composition for treating and stabilizing soils, in particular wet soils, comprising, in the form of a powder having a particle size less than 2 mm, quicklime and/or calcium-based hydraulic binders, as well as a non-aqueous fluid additive capable of agglomerating the finer particles of the composition together.
Claims18
Composition for treating and stabilizing soils, in particular wet soils, comprising, in the form of a powder having a particle size less than 2 mm, quicklime and/or calcium-based hydraulic binders,
- characterized in that it additionally includes a non-aqueous fluid additive having a power to agglomerate the finer particles of the composition.
Composition for treating soils according to any one of claims 1 to 4, characterized in that it has a particle size distribution in which the particles larger than 1 mm represent less than 20% of the total composition, advantageously less than 10% thereof, and preferably less than 1% thereof.
Composition according to any one of claims 1 to 5, characterized in that the said additive is hydrophobic and loses its agglomerating power during hydration of at least part of the quicklime or hydraulic binder.
