Dry soil mixing Keller North America

Dry soil mixing is a ground improvement technique that improves soft, high moisture clays, peats, and other weak soils, by mechanically mixing them with dry cementitious binder to create soilcrete. To construct columns, a high-speed drill advances into the ground a drill rod with radial mixing paddles near the bottom of the drill string.

Jan 01, 2021  Dry solidification consists in mixing the soil with a binding agent (e.g. cement, ash, cement-ash mixtures) without additional water. This treatment allows the soil to dry, caused by the hydration process, and then bind. The technology is used to strengthen organic soils and cohesive soils with low shear strength in conditions without drainage.

Soil - Wikipedia

A typical soil is about 50% solids (45% mineral and 5% organic matter), and 50% voids (or pores) of which half is occupied by water and half by gas. The percent soil mineral and organic content can be treated as a constant (in the short term), while the percent soil water and gas content is considered highly variable whereby a rise in one is simultaneously balanced by a reduction in the other.
