A cubic yard (symbol yd 3) [1] is an imperial / U.S. customary (non-SI non-metric) unit of volume used in Canada and the United States. It is defined as the volume of a cube with sides of 1 yard (3 feet , 36 inches , 0.9144 meters ) in length .
The placement consisted of 10,251 cubic yards of concrete placed in 58.5 hours using two concrete pumps and two dedicated concrete batch plants. Upon curing, this placement allows the 50,180-square-foot (4,662 m 2 ) cofferdam to be dewatered approximately 26 feet (7.9 m) below sea level to allow the construction of the Inner Harbor Navigation ...
Within a single 24-hour period in October 2005, a fleet of 30 concrete trucks made 600 trips to pour 5,000 cubic yards (3,800 m 3) of concrete, and thus create a 200-by-66-by-10-foot (61.0 by 20.1 by 3.0 m) concrete "mat". [101] The mat serves as the base of the building, from which its spine rises.
Centralized batch systems are limited by the size of the fleet. It may take upwards of 10 minutes to batch and load out one 9–12 cubic yards (6.9–9.2 cubic metres) truck depending on the plant size and type.

Trucks weigh 9,100 to 14,000 kilograms (20,000 to 30,000 lb), and can carry roughly 20,000 kilograms (40,000 lb) of concrete although many varying sizes of mixer truck are currently in use. The most common truck capacity is 10 cubic yards (7.6 m 3). Most concrete mixers in the UK are limited to a speed of 90 kilometres per hour (56 mph).
There are corresponding units of area and volume, the square yard and cubic yard respectively. These are sometimes referred to simply as "yards" when no ambiguity is possible, for example an American or Canadian concrete mixer may be marked with a capacity of "9 yards" or "1.5 yards", where cubic yards are obviously referred to.
Gypsum concrete is lightweight and fire-resistant. A 1.5-inch slab of gypsum concrete weighs 13 pounds per square foot versus 18 pounds per square foot for regular concrete. [10] Even though gypsum concrete weighs less, it still has the same compressive strength as regular concrete, based on its application as underlayment or top coat flooring ...
