Compressed earth block. A compressed earth block (CEB), also known as a pressed earth block or a compressed soil block, is a building material made primarily from a 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 ...
Soil cement. Soil cement is a construction material, a mix of pulverized natural soil with small amount of portland cement and water, usually processed in a tumbler, compacted to high density. Hard, semi-rigid durable material is formed by hydration of the cement particles. Soil cement is frequently used as a construction material for pipe ...
The hydraform block is made from soil cement which is a mixture of soil, cement and water, and is hydraulically compressed to form a high quality interlocking soil block. Soil from the building site can be used to manufacture building blocks. Sandcrete and landcrete are similar materials but are not compressed. Hydraform interlocking blocks.
This type of soil strengthening usually needs outer facing walls (S.R.W.'s – Segmental Retaining Walls) to affix the layers to and vice versa. [11] The wall face is often of precast concrete units [7] that can tolerate some differential movement. The reinforced soil's mass, along with the facing, then acts as an improved gravity wall.
A diagram of a mechanically stabilized earth wall as it would be modeled in a finite element analysis. Mechanically stabilized earth (MSE or reinforced soil) is soil constructed with artificial reinforcing. It can be used for retaining walls, bridge abutments, seawalls, and dikes. [1][2] Although the basic principles of MSE have been used ...
If there is more than 15% clay it may take more than 10% cement to stabilize the soil, which adds to the cost. [20] If earth contains little clay and holds 10% or more cement, it is in effect concrete. Cement is not particularly environmentally friendly, since the manufacturing process generates large amounts of carbon dioxide. [22]
