Soil remediation by molecular binding for producing beneficial use determined polymer concrete products
10676397 · 2020-06-09 ·

A method for soil remediation by molecular binding for producing beneficial use determined polymer concrete product that removes hazardous pollutants from a quantity of contaminated soil. Hazardous pollutants are identified though chemical analysis in order to select at least corresponding polymer and at least one corresponding binder for each hazardous pollutant present in the contaminated soil. The at least one polymer chemically bonds with the hazardous pollutant in order to neutralize the hazardous pollutant within the contaminated soil to form a polymer concrete product. The polymer concrete product is then used as a concrete substitute for construction applications.

Method for treating polluted soil by a hydraulic binder with mayenite phase

A method for treating polluted soils, includes mixing the soil with a hydraulic binder, wherein the hydraulic binder includes: as the only high-alumina clinker, a high-alumina clinker including more than 80 wt % of mayenite C12A7 phase or a mayenite isotope, the high-alumina clinker making up at least 70 wt % of the weight of the hydraulic binder; and 1 wt % to 30 wt %, relative to the total weight of the binder, of lime.

Construction material without a hydraulic binder

The invention relates to a method for producing a solid construction material which is preferably substantially free of hydraulic binder, comprising the steps of: a. extracting a mineral fraction comprising argillaceous particles of a soil; b. optionally adjusting the particle size of the mineral fraction extracted, in particular in relation to its clay, sand, gravel or loam content, if necessary; c. preparing a first aqueous grout from at least one part of the mineral fraction extracted and optionally adjusted in terms of particle size; d. adding a dispersant that can disperse the argillaceous particles in the first grout in order to obtain a second aqueous grout, e. adding a coagulant that can promote the agglomeration of the argillaceous particles in the second grout in order to obtain an aqueous construction material grout; f introducing the construction material grout into a formwork; and g. allowing the evaporation of the water contained in the material grout in order to obtain a solid construction material.
