Batch plants combine a precise amount of gravel, sand, water and cement by weight (as per a mix design formulation for the grade of concrete recommended by the structural engineer or architect), allowing specialty concrete mixtures to be developed and implemented on construction sites.
Reduces waste and associated costs by providing exact quantities. No risk of premature stiffening of concrete if delays are encountered. Permits delivery of smaller quantities of concrete. Night time works do not require the re-opening of a concrete batch plant. Flexibility to alternate between multiple concrete mixes as required for the ...
Twin shaft concrete mixer for a concrete plant. Twin-shaft mixers, known for their high intensity mixing, and short mixing times. These mixers are typically used for high strength concrete, RCC and SCC, typically in batches of 2–6 m 3 (2.6–7.8 cu yd). Vertical axis mixers, most commonly used for precast and prestressed concrete.
A 1924 issue of Concrete magazine said that the operation at 1000 La Brea Ave. appeared to be "the pioneer mixing plant in the West," the first of its kind offering "ready-mixed Portland cement ...
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 ...
