The deep soil mixing columns are typically 0.6 to 2.4 m in diameter and depths of up to 50m can be reached depending on the nature of the ground conditions and the technique employed. [1] Steel reinforcement can be inserted into fresh soil-mix to increase bending resistance of deep soil mixing columns used for excavation control. [2]
A cement-modified soil contains a relatively small proportion of Portland cement, less than in ordinary soil-cement. [1] The result is caked or slightly hardened material, similar to a soil, but with improved mechanical properties such as lower plasticity, increased bearing ratio and shear strength, and decreased volume change. The purpose of ...
The resulting hard substance, called 'clinker', is then ground with a small amount of gypsum (CaSO 4 ·2H 2 O) into a powder to make ordinary Portland cement, the most commonly used type of cement (often referred to as OPC). Portland cement is a basic ingredient of concrete, mortar, and most non-specialty grout. The most common use for Portland ...
A compressed earth block (CEB), also known as a pressed earth block or a compressed soil block, is a building material made primarily from an appropriate mix of fairly dry inorganic subsoil, non-expansive clay, sand, and aggregate. Forming compressed earth blocks requires dampening, mechanically pressing at high pressure, and then drying the ...
A stabilized soil mixing plant is a combination of kinds of machines used for mixing stabilized soil, which is used for highway construction, municipal road projects, and fertile airport areas. The plant produces stabilized soil with different gradings in a continuous way.

Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non-specialty grout. It was developed from other types of hydraulic lime in England in the early 19th century by Joseph Aspdin , and is usually made from limestone .
The reclamation of land from surrounding waters is used in Singapore to expand the city-state's limited area of usable, natural land. Land reclamation is most simply done by adding material such as rocks, soil and cement to an area of water; alternatively, submerged wetlands or similar biomes can be drained.
