for its Waste Recovery System
Dry Anaerobic Digester Turns Organic Waste Into Electricity and High-Quality
SAN JOSE, Calif., Aug. 21, 2013
SAN JOSE, Calif., Aug. 21, 2013 /PRNewswire/ -- Central Concrete, a business
unit of U.S. Concrete, Inc. (NASDAQ-USCR), and the leader in delivering
low-CO concrete to the San Francisco Bay Area, along with Jos. J. Albanese,
a leading Bay Area concrete contractor, today announced that they developed
several innovative concrete solutions to address the aggressive specifications
required by the Zero Waste Energy Development Facility currently under
construction in San Jose, California. Not only did Central Concrete and Jos.
J. Albanese respond to a significant acceleration in the schedule, but they
devised mixes and placement solutions that addressed the unique issues faced
when working with waste materials. The project is being constructed by South
Bay Construction, Inc., a leading construction firm, with headquarters in
San Jose's Zero Waste Energy Development Facility is targeted for completion
in December 2013 and is expected to be the largest Dry Anaerobic Digestion
(AD) facility in the United States. The Dry AD process converts high solid
organic waste into green energy. It is projected that the plant will be
capable of processing 90,000 tons of waste and producing up to 1.6 megawatts
of renewable power. This is enough to power 2000 homes.
The key to building a plant of this type was making sure that the waste
materials, such as methane gas, were properly contained. In addition, the team
needed to address the corrosive nature of these waste products. In response to
these challenges, Central Concrete evaluated several mix design combinations,
both in the field and in the lab, to produce the desired performance. The
result—dense, durable concrete mixes with tight, low shrinkage specifications.
These mixes not only delivered the low water/cement ratio required, but the
highly workable mixes allowed Jos. J. Albanese's crew to place the concrete
more efficiently, significantly helping them to meet the accelerated build
The Jos. J. Albanese team applied the Central Concrete mixes using a process
called wet-mix shotcrete. This process involved pumping Central's prepared
concrete through a nozzle. Compressed air is then introduced and a "gun"
delivers the concrete. Not only does this wet-mix process allow larger volumes
to be placed in less time, but the ability to adjust the water allowed the
team to meet the hardening properties required for the job. In addition, the
teams from Central and Jos. J. Albanese poured and placed five extremely large
mat floors in the very early hours of the morning to further assist the owner
in accelerating the schedule.
"We chose to work with Jos. J Albanese and Central Concrete on this project
for their knowledge in shotcrete applications and their ability to get it
done", said Jim Richley, Sr. Project Manager of South Bay Construction.
