Abstract
The present disclosure provides compositions and methods for accelerating soil stabilization using carbon dioxide.
Claims28
A method of soil stabilization, the method comprising,
- contacting a composition comprising soil, lime, and water, with exogenous carbon dioxide sufficient to create and/or maintain a continuous gas phase in the composition for a period of time sufficient to precipitate carbonate minerals in the composition.

A method of accelerated soil stabilization, the method comprising,
- contacting a composition comprising soil, a metal oxide and/or metal hydroxide and water, with exogenous carbon dioxide sufficient to create and/or maintain a continuous gas phase in the composition for a period of time sufficient to precipitate carbonate minerals in the composition.

A method of soil stabilization, the method comprising,
- (a) determining a soil type, void ratio, and/or degree of saturation for a composition comprising soil, a metal oxide and/or metal hydroxide, and water;
- and
- (b) contacting the composition with exogenous carbon dioxide sufficient to create and/or maintain a continuous gas phase in the composition for a period of time sufficient to precipitate carbonate minerals in the composition,
- wherein the period of time is determined by the soil type, degree of saturation, and/or water content.
