Reactive powder concrete, also known as ultra-high-performance concrete, can be even stronger, with strengths of up to 800 MPa (116,000 PSI). [4] These are made by eliminating large aggregate completely, carefully controlling the size of the fine aggregates to ensure the best possible packing, and incorporating steel fibers (sometimes produced ...
A benefit of pre-topped double tees is a higher quality concrete for more durable surface to reduce traffic wears. Factories can produce the topping with minimum concrete strength of 5,000 psi. In some areas, the strength can be 6,000-8,000 psi. This compares to the field-placed concrete topping with the lower concrete strength of 4,000 psi. [6]
Lightweight concrete is often achieved by adding air, foams, or lightweight aggregates, with the side effect that the strength is reduced. For most routine uses, 20 to 32 MPa (2,900 to 4,600 psi) concrete is often used. 40 MPa (5,800 psi) concrete is readily commercially available as a more durable, although more expensive, option.
Typically, around 3,000 psi (21 MPa) of pressure is applied in compression, and the original material volume is reduced by about half. Creating CEBs differs from rammed earth in that the latter uses a larger formwork into which earth is poured and manually tamped down, creating larger forms such as a whole wall or more at one time, rather than ...
When constructing a retaining wall from eco-blocks, a stable foundation is still required. In July 2015, a 70-year-old man in Washington died after an ecology block wall under construction on a sand foundation collapsed, and his legs were crushed by a 3,600-pound (1,600 kg) block. [1] [12]
Cantilevered retaining walls are made from an internal stem of steel-reinforced, cast-in-place concrete or mortared masonry (often in the shape of an inverted T). These walls cantilever loads (like a beam ) to a large, structural footing, converting horizontal pressures from behind the wall to vertical pressures on the ground below.

A pervious concrete street in 2005. Pervious concrete (also called porous concrete, permeable concrete, no fines concrete and porous pavement) is a special type of concrete with a high porosity used for concrete flatwork applications that allows water from precipitation and other sources to pass directly through, thereby reducing the runoff from a site and allowing groundwater recharge.
