Water-soluble soil conditioners offer the following benefits: [10] increase pore space in soils containing clay; increase water infiltration into soils containing clay; prevent soil crusting; stop erosion and water runoff; make friable soil that is easy to cultivate; make soil dry quicker after rain or irrigation, so that the soil can be worked ...
Synthetic polymers began replacing other chemical binders for soil stabilization in agriculture in the late 20th century. [1] Compared to traditional chemical binders, polymer soil additives can achieve the same amount of strengthening at much lower concentrations – for example, mixtures of 0.5-1% of various biopolymers have strength levels that match or exceed those of 10% cement mixtures ...
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 ...

Clay body being extruded from a de-airing pug. A pugmill, pug mill, or commonly just pug, is a machine in which clay or other materials are extruded in a plastic state or a similar machine for the trituration of ore. [1] Industrial applications are found in pottery, bricks, cement and some parts of the concrete and asphalt mixing processes. A ...

Agricultural steam engines took over the heavy pulling work of oxen, and were also equipped with a pulley that could power stationary machines via the use of a long belt. The steam-powered machines were low-powered by today's standards but because of their size and their low gear ratios, they could provide a large drawbar pull. The slow speed ...
A soil stabiliser (also called a pulvimixer) is a construction vehicle with a powered metal drum that has rows of mixing blades or paddles. It makes soil cement by blending soil, a binder agent (usually Portland cement or lime ) and water together with paddles in the mixing chamber instead of a concrete mixer and usually does not cut or mill ...
