Toscas to Provide Paving Effort Update

0020a-5x7_FurlaStudioRegister for Friday's Paving Committee advocacy conference call which will include an update from Jim Toscas, PCA president and CEO, on the new industry-wide paving effort. The Paving Committee holds monthly paving advocacy conference calls to share best practices and avenues to successful advocacy and promotional efforts. The next call is June 12 at 11 a.m. ET.

This month’s call will feature:

• An overview of an industry wide paving effort moving forward – Jim Toscas, PCA president and CEO.

• An educational presentation on shrinkage, freeze thaw, and formation factor, in a collaborative research effort that leverages MIT Concrete Science – Professor Jason Weiss, Purdue University.

• Efforts that led to PennDOT selecting full-depth reclamation (FDR) for more than 16-miles of SR31 in northwestern Pennsylvania – David Cannon, PCA Northeast Region road recycling specialist - Pennsylvania.

The calls are ideal for members of PCA committees, regional promotion committees, ACPA chapters, and ready-mixed concrete state affiliates.

Research Brief: Streamlined Embodied LCA of Residential Buildings

Traditional life-cycle assessment (LCA) is time, resource, and data intensive. For complex systems like residential buildings, these demands can mean that assessments are carried out after important design decisions have already been made. CSHub researchers have developed a streamlined method that requires significantly less time and data than traditional methods, which can reduce expense and uncertainty earlier in the residential construction process.

Research Brief: Modeling Freeze-Thaw in Concrete

Damage to concrete slabs during freezing and thawing cycles represents a major challenge to pavement durability and resilience. A recent MIT brief explores freeze-thaw cycles in concrete using models that simulate water and ion transport. The research supports past findings that damage is not primarily caused by the expansion of freezing water in the cement paste, but points instead to the impacts of deicing agents that find their way into the material's nanostructures.

James P. Sunderland, 1928-2015

James Sunderland2 1998 (3)The Ash Grove Cement Company announced today the passing of James P. Sunderland, former company chairman and president, on May 27.

Sunderland joined the Ash Grove Lime and Portland Cement Company in 1957 as its corporate secretary in Kansas City. In his 43-year career at Ash Grove Cement, he held several leadership positions including serving as the company’s chairman and president. During Sunderland’s tenure, Ash Grove Cement became one of the largest portland cement producers in the U.S. 

From 1974-1991, Sunderland served on the PCA Board of Directors. In addition to being a member of PCA’s Executive, Nominating, Long-Range Planning, Market Development, and Finance committees, he was chair of the Washington Affairs Committee. During his tenure as chair, the number one priority of PCA was the future of Washington, DC, operations and Sunderland oversaw the Association’s expanded operations in Washington.

Donations in Sunderland’s memory can be made to the Greater Kansas City Community Foundation

Advocacy Aids Passage of North Central Region Transportation Laws

Transportation advocacy is proving successful in the PCA North Central Region. In May, the Nebraska legislature passed a fuel tax increase to fund transportation. The $.06 increase will generate $75 million additional revenue annually for county and municipal infrastructure construction. This measure bolsters local investment in alignment with the state system focused $1.2 billion Build Nebraska Act which went into effect July 2012.

The Nebraska bill is the latest in several transportation bills that have garnered support in the PCA North Central Region. Iowa passed a $.10 gas tax increase in February, generating $215 million. This measure is the second half of the TIME21 funding recommendation which totals $385 million additional revenue annually. South Dakota passed an $85 million enactment in March including a $.06 fuel tax increase. North Dakota enacted a $1.89 billion biennium infrastructure construction funding measure in February. All of these bills went into effect virtually immediately, providing “catch up” funds and facilitating 2015 project lettings.   

Whether coalition leadership, fundraising, in-session legislator contacts, or capital rallies and media events, PCA has been a vital participant in regional advocacy efforts.

North America Leads Global Cement Growth

Global cement consumption is expected to grow throughout 2015 and continue throughout the next year, but at a slower rate than in the past. 

A report released by PCA indicates that cement consumption among developed economies increased by roughly 9.2 million metric tons in 2014, followed by another 9 million ton increase in 2015. With an expected growth of more than 7.4 million metric tons, the North American region will expand at a faster pace than most other developed countries due to continued national economic growth.

Global economic and cement market conditions impact the United States cement industry in a myriad of ways. Healthy world economies suggest strong export opportunities for the United States – impacting jobs and consequently to some degree the level of construction activity in the United States. World growth conditions also influence concrete’s relative price versus steel, asphalt, and lumber - impacting its competitive position. The PCA report provides rough assessments of global economic and cement market conditions that could impact the United States cement industry.

PCA projects global cement consumption to record sustained growth during 2015-2018, but at a less robust pace than previously expected. World cement consumption is expected to grow 2.2 percent in 2015, 3.7 percent in 2016, and remain near 4 percent growth during 2017-2018. World cement consumption grew an estimated 4.6 percent in 2014 from 4.0 billion metric tons in 2013 to 4.3 billion metric tons.

Oregon City Gains Strength with Cement-Treated Base

ICTB

To balance the triple bottom line – environmental, social and economic needs – the city of Eugene, Oregon, took a time tested technique to strength roads and gave it a new twist. In the summer of 2014, the city developed a new paving technique utilizing an in-place cement treated base (ICTB) slurry to strengthen road subgrades.

As featured in the May 2015 APWA Reporter, ICTB provided Eugene with a cost-effective way to strengthen the subgrade by utilizing existing materials rather than the conventional removal and replacement of the existing base. Prior to 2014, Eugene specified cement powder for ICTB projects, but that year considered the potential for residential impacts due to airborne cement dust. The city and Lane County geotechnical lab developed a mix design that uses a cement and slurry paste to minimize dust.

Eugene recently utilized the process to pave 1,300 feet of residential streets and plans to continue to utilize this process for future projects.

PCA Introduces Particulate Matter Compliance Workshop

PCA will offer a particulate matter (PM) compliance one-day workshop on June 23, 24, or 25, to help manufacturers meet National Emissions Standards for Hazardous Air Pollutants (NESHAP). The workshop was introduced after an overwhelming response to the panel discussion “Getting to .07: PM Compliance at Today's Cement Plant" at the recent IEEE-IAS/PCA Cement Industry Technical Conference in Toronto, Ontario.

The Skokie workshop is ideal for staff involved with demonstrating and maintaining compliance with the PM-related requirements of the portland cement maximum achievable control technology (MACT) standards. Covered topics include:

  • Basic operation and troubleshooting of dust collection systems including industry best practices, how to identify and prevent common bag house problems, addressing the causes, and how system design impacts reliability.
  • Reading the signs: dust collector controls and how these can impact compliance including what should be monitored, what the data tell us, and how education and training of plant personnel can impact compliance.
  • Preparing for effective performance testing including preliminary evaluations of the source, detailed logistics for test day, the potential for using spiking to optimize your operating parameter limits, and considerations for alarm limits on your PM CPMS.

The 8-hour program is free to all PCA members and associate members but registration is required. To register, please click on one of the links below:

Discounted hotel rates are available at the Hampton Inn & Suites Chicago-North Shore/Skokie. Please call 1-847-583-1111 and mention that you are attending the PCA PM Compliance Workshop to receive the special discounted rate.
