Building a New
PATH with Concrete
Design
is underway for a new transportation hub for the Port Authority
Trans-Hudson (PATH) that would connect commuter trains from
New Jersey to the New York City subway system. The $1.7-billion
facility will restore mass transit in Lower Manhattan in the
aftermath of 9/11.
The special structure is being designed by the Downtown Design
Partnership, a joint venture of Santiago Calatrava, DMJM-Harris,
Parsons, and STV. About 40 subcontractors, led by Weidlinger
Associates (New York Office), are involved in the design.
PCA's Mike Mota is working with Weidlinger
to provide technical assistance on the design along with local
allies, the New York City Concrete Promotion Council and PERI
Forms. The discussion focuses on the constructibility aspects
of the massive reinforced white concrete structure, which consists
of arches spanning 150 feet supported by box girders spanning
about 200 feet. Contact

| Energy Performance Indicator
Now Available for Cement Industry
The U.S. Environmental Protection Agency
(EPA) announced last week that an Energy Performance Indicator
(EPI) is now available for cement manufacturers.
The EPI scores the energy efficiency of a single cement plant
and allows the plant to compare its performance to that of
the entire industry. The EPI is an outgrowth of the EPA’s
Energy Star Industrial Focus program. The tool is intended
to help cement plant operators identify opportunities to improve
energy efficiency, reduce greenhouse gas emissions, conserve
conventional energy supplies, and reduce production costs.
The cement industry EPI was developed by the
EPA in cooperation with PCA, technical support from Argonne
National Laboratory in Illinois, and validated at several
cement plants. The tool scores a plant from 1 to 100. A score
of 75 or higher deems the plant as energy efficient.
"This program reflects the cement
industry’s commitment to sustainable manufacturing and
to working with the EPA to improve energy efficiency and reduce
emissions,” Andy O’Hare, PCA vice president of
regulatory affairs, said. “Although a voluntary program,
nearly half of U.S. cement companies are participating in
the Energy Star Industrial Focus program.”

Sidney Tar Ponds
Team Tours Milwaukee Site
PCA arranged and hosted a visit by the CEO
and staff of the Sydney Tar Ponds Agency to an active solidification/stabilization
site in Milwaukee, Wis. The group got a first-hand look at cement-based
S/S treatment
at the Westside remediation site, a former manufactured gas
plant (MGP) site. They also met with environmental engineering
firms and remediation contractors in Milwaukee and Chicago.
The Westside site is the second MGP site in Wisconsin to use
in-situ cement-based S/S treatment to remediate coal-tar
contaminated soil. Another MGP site in Racine, Wis., will begin
after the Milwaukee site is finished this summer.
The Agency is charged with the cleanup
of Sydney Tar Ponds, site of a former steel plant in Nova Scotia
where 100 years of steel and coke production left more than
a million tons of contaminated soil and sediment. Hazardous
constituents include coal tars and poly-chlorinated byphenyls
(PCBs). The Canadian government committed C$400 million to remediate
the site over 10 years. If the panel rules in favor of cement-based
stabilization/solidification, the project will use an estimated
100,000 tons of cement during the 10-year cleanup. Another portion
of the site—the Sysco Cooling Pond—is already slated
for treatment with cement. More

PPI: Steel, Asphalt Continue Climb
According to the July Producer Price Index
(PPI), steel prices gained 3.7% and asphalt prices rose 3.1%
for the month. Concrete was up 1.4%; lumber declined 1.8%.
July marks the thirteenth straight monthly increase for asphalt.
Asphalt prices now are 37% higher than one year ago and are
up 23.1% in the last six months. Steel prices rose 18.2% in
the last year and 10.4% in the last six months. Concrete prices
have risen 10.8% and 3.7%, respectively, over the same time
periods. Lumber prices are 4.6% less than a year ago.

Salt River Materials Adopts Sustainability
Initiative
The Board of Directors for Salt River Materials
Group (Phoenix Cement) has approved a resolution establishing
a sustainability initiative.
The resolution creates a sustainability working group to coordinate
the company's existing and future efforts to measure, optimize,
and communicate sustainable performance. From energy efficiency
to environmental stewardship, the initiative is intended to
produce measurable benefits by meeting or exceeding performance
benchmarks.
Says President and CEO Roger Smith: "We intend to make
a major positive impact on our two greatest resources: our people
and our environment.”

TXI Celebrates
Riverside Cement Centennial
TXI announced the 100 year anniversary
of Riverside Cement. Incorporated August 23, 1906, as the
Southern California Cement Company, the company changed its
name to Riverside Cement Company in the late 1920s. After
years of various owners, Riverside Cement was most recently
purchased by TXI in 1998.
TXI Riverside Cement will begin its next hundred years with
completion of its 2.2-million-ton plant expansion and modernization
at Oro Grande, Calif.

From Last Week:
PCA Name Change? No Thanks.
Question: With the advent of blended cements
and supplementary cementing materials, the industry has made
the transition from cement to cementitious. Moreover, the
term “portland” is archaic and confusing. Should
PCA change its name to better reflect the make-up of the industry
and project a more modern image?
Responses (percent):
No, don't change it. PCA's reputation and legacy are
too important: 111 (60.66%)
Yes, change PCA's name to something that better describes
the association and the industry: 72 (39.34%)
Among the many comments sparked by this question:
"I feel the industry needs to remain consistent. Slag,
fly ash, and pozzolans have their own organizations and do
not share the extreme capital requirements and regulatory
hurdles as manufacturers of clinker. Portland cement is the
overwhelming percentage volume and dollar value of cements
or cementitious products."
"The PCA has an excellent reputation and presence in
the industry. A change would erase its image as the leader
in cement and concrete technology. 'If it ain't broke, don't
fix it1'"
"One might consider reverting to a acronym-based name
that is not spelled out—like ASTM International.
PCA is mentioned by reference in many industry standards and
specifications which will be hard to change."
"Change to Cement Association of North America...current
name hinders progress and effectiveness of association efforts
in lobbying and media efforts. "
"The industry as a whole needs a brand new lift. The
rationale of a reputable body such as PCA (openly) adopting
changes (for the betterment of the cement industry) will send
a positive message to the other players."
"You have brand value in the PCA name. Just broaden your
scope."
"NO! The PCA has lost most of its influence already when
they removed the field engineers. Don't put the last nail
in the coffin!"

Strength And Durability: Full-Depth Reclamation Solves Construction
Problems in Wet and Weak Soils: This reprint of
an article from Pacific Builder and Engineer magazine, June
2006, describes the rehabilitation of failed flexible pavement
at the Port of Seattle’s Terminal 115. The heavy loads
encountered at the facility had caused deterioration of the
existing pavement and made rehabilitation necessary. Many pavement
correction options were evaluated, but full-depth reclamation
(FDR) using portland cement was chosen as the most cost-efficient
solution, especially considering Seattle’s wet environment.
Eight inches of rain fell during the FDR construction at the
Port, but few delays were encountered, resulting in minimal
tenant disruption. FDR was able to accelerate the construction
process and reduce downtime at the terminal so much that the
Port subsequently added five additional acres to the project
(RP430; $7.50 for a pack of 25, no discount; PDF is free).
