Abstract: A method of a nano-grout fabrication comprises the steps of: a) acquiring a batch cement for a ball mill, b) forming in the ball mill a cement powder also called a nano-cement powder, c) pouring the nano-cement powder obtained in step b) to a rotary mixer, d) adding water to the rotary mixer, e) mixing the water and the nano-cement powder until a homogenous mixture of the nano-grout or the nano- slurry is obtained, f) pouring the nano-grout or the nano-slurry obtained in step e) from the rotary mixer to a distributing device, where a grouting material is applied to the prepared construction site or specific places of the construction site and is subjected to curing for a predetermined amount of time.

Abstract: A method for production of a modified clay powder comprises the steps of: a) acquiring batch clay, and b) forming a modified clay powder with an average particle size of between 2 nm and 150 nm. The main groups of clays include kaolinite, montmorillonite, bentonite, smectite, and illite.

Abstract: A use of nano-regolith for preparing a construction material, wherein the particle size of the nano-regolith is between 2 nm and 100 nm and a method for production of a modified regolith powder, comprising the steps of: a) acquiring a batch regolith, b) forming the modified regolith powder with an average particle size of between 2 nm and 100 nm, wherein forming the modified regolith powder is performed by grinding the batch regolith in a rotating ball mill, wherein the ball mill includes a plurality of mill balls, wherein the average particle size of the modified regolith powder produced is between 2 nm and 100 nm, and a method for production of a modified regolith suspension, comprising the steps of: a) acquiring a batch regolith, b) forming the modified regolith powder with an average particle size of between 2 nm and 100 nm, wherein forming the modified regolith powder is performed by grinding the batch regolith in a rotating ball mill, wherein the ball mill includes a plurality of mill balls, wherein the

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.

Abstract: An earth anchor comprises at least one anchoring part connected by a connecting part to the driving part, wherein the driving part is designed for installing the anchoring part in the desired position in the soil and for connecting to an external structure. The anchoring part and the connecting part are manufactured with a polymer on a 3D printer.
