Abstract
A method for improving the stability of a soil sample comprises a steps of: a) acquiring the soil sample, b) acquiring a cement, c) forming a cement powder (nano-cement) with an average particle size of between 2 nm and 150 nm, optionally preparing a suspension of the nano-cement in water, d) mixing the cement powder or the suspension of the cement powder in water with the soil sample in a weight ratio of between 1:100 and 1:1 of the cement powder to the soil sample, respectively, e) applying the mixture obtained in step d) to the required construction site, optionally by applying the PWS mixture.
Claims7
A method for improving the stability of a soil sample, the method comprising steps of:
- a) acquiring the soil sample,
- b) acquiring a batch cement,
- c) forming a modified cement powder with an average particle size of between 2 nm and 150 nm,
- d) forming an aqueous suspension of the modified cement powder,
- e) placing the aqueous suspension of the modified cement powder in an ultrasonic water bath for 5-30 min to disperse the modified cement powder for geochemical fractionation,
- f) mixing the aqueous suspension of the modified cement powder obtained in step e) with the soil sample in a weight ratio of the aqueous suspension of the cement powder to the soil sample of between 1:100 wt/wt and 18:100 wt/wt, wherein the result of step f) is a spray mixture,
- g) applying the spray mixture obtained in step f) to the predetermined construction site,
- h) allowing the structure obtained in step g) to harden for a curing time.
