CTLGroup Opens Laboratory in Qatar
CTLGroup opened a new laboratory in Doha, Qatar last week. CTLGroup President and CEO Brent Nixon and Chief Operating Officer Tim Tonyan, along with more than 60 stakeholders from the architectural, engineering, construction, cement and concrete industries, attended the May 28 grand opening ceremony in Doha.
CTLGroup-Qatar conducts a wide range of testing services for concrete, cementitious materials, aggregates, building systems, soils, and asphalt.
“As a world leader in laboratory testing and materials analysis for the construction industry, CTLGroup-Qatar aligns with both our strategic vision and Qatar’s National Vision 2030. We are raising the bar on professional and technological capabilities to support the region’s building aspirations,” Nixon said.
CTLGroup-Qatar is ISO 17025:2008 and ISO 9001:2008 certified; ISO 14001:2004 and OHSAS 18001:2007 compliant.

Lafarge Employees Named Volunteer Champions
During National Volunteer Month this April, Lafarge North America supported more than 20 environmental and community improvement projects. Lafarge U.S. volunteer champions worked hard to organize efforts throughout the month, leading to nearly 300 employees devoting approximately 1,500 hours to the community.
“We are proud of everyone who has been participating in volunteering activities, not only during the month of April, but since the start of the year,” said John Stull, president and CEO, Lafarge U.S. “Lafarge is committed to supporting our neighbors by devoting time and providing donations to the programs and services most important to the communities in which we work and live.”
During National Volunteer Month, employees participated in several adopt-a-highway cleanup projects, including one in Paulding, Ohio, where 26 employees volunteered for eight hours each, totaling 208 hours of devoted time. Other projects included disaster relief support for those affected by tornadoes in Illinois, Earth Day cleanup projects, and support for local food banks.
On a global scale, Lafarge Group’s goal is to contribute one million volunteer hours per year across all Lafarge operations by 2020.
Nonresidential, Public Sectors Lead 2014 Cement Consumption Increases
Nonresidential and public sector growth in 2014 led to a 8.7 percent increase in portland cement consumption compared to 2013. According to PCA’s 2014 Apparent Use of Portland Cement, State & Market Report, the nonresidential market increased 19.2 percent, with the public sector right behind it at 9.6 percent. For the first time since 2010, the residential sector dragged down cement consumption, with a 1.7 percent decrease from 2013.
Although single-family and multi-family subsectors were up 5.0 percent and 13.9 percent, respectively, the home renovation market decreased 18.7 percent and dragged down overall residential cement consumption. Nearly each nonresidential component of apparent use saw growth, with the exception being religious, down for the second straight year. Similarly, public construction’s only drag was military/public service, falling 5.2 percent.
The 2014 Apparent Use of Portland Cement by State and Market is an allocation to 46 construction markets of U.S. Geological Survey’s (USGS) state cement shipments. The allocation is accomplished by determining construction activity in each county from Dodge Data & Analytics and a variety of other sources, applying cement usage factors, and adjusting the implied state totals to the reported USGS totals.

China Cement Association Delegation Visits Skokie
China Cement Association delegates recently met with PCA and CTLGroup staff in Skokie to discuss technologies to reduce air emissions and meet new environmental regulations.
China’s State Council seeks to invoke limits on air emissions similar to rules set by the U.S. Environmental Protection Agency. A revised law increases vehicle standards for China’s 264 million vehicles as well as for the coal industry and manufacturing. It will also include an early-warning system and contingency procedures for when pollution spikes in particularly affected areas, such as the Beijing-Hebei-Tianjin region, which in the third quarter of 2014 suffered from pollution 45 percent of the time, according to a Reuters report.
The China Cement Association has 1,200 cement companies as members. Leading the association’s seven person delegation were Wang Yutao, deputy secretary general, and Grace Chen, deputy director international.
Rick Bohan, manufacturing technology director, Steve Kosmatka, research & technical services vice president, David Shepherd, sustainable development director, and Guiyen Wang, librarian and research engineer, attended the discussion on behalf of PCA. CTLGroup was represented by Xiuping Feng, materials scientist, and Gary Gan, structural and transportation laboratory principal engineer.

Codes & Standards
Building Codes Need to Re-Focus on Life and Property Protection
In the May 2015 Masonry magazine, PCA Codes and Standards Manager Jay Hall writes “property protection has taken a back seat in the building codes, and that needs to change.”
Hall points to the efforts of the Masonry Alliance for Codes and Standards (MACS) to develop and submit building code changes relevant to safety during and after a natural or manmade disruptive event.
During the last couple of decades, minimal cost and affordability, combined with maintaining or improving life safety during fire and other emergency events, have been primary in the development of building codes, he says.
Residential fire sprinkler systems are now required for all residential occupancies and have been extremely successful in reducing fire deaths nationwide. However, hourly fire resistance ratings for structure elements once required by code have been reduced or eliminated based on the presence of a sprinkler system. The building code no longer guarantees a structure’s performance and continued usability. Read article

Full-Depth Reclamation Hastens Airport Restoration
A strong, resurfaced runway greets pilots coming to the Research Triangle of North Carolina thanks to the use of full-depth reclamation (FDR) with cement. The airport serves as a premier corporate gateway to Raleigh, Durham, and Chapel Hill.
In 2013, the need to reconstruct the busy airport’s runway on an accelerated time frame made FDR the right process for the job. Contractors pulverized the entire runway, completed the grading, removed excess materials and completed the FDR process in just 11 days and the airport opened in 50 days.
The runway reconstruction increased the weight capacity from 80,000 to 100,000 pounds. The project utilized 2,050 tons of cement at a depth of 12 inches, and covered an area of 72,500 square yards.
In addition to the new runway, installation of energy efficient LED bulbs increased safety and reduced operating cost.

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.
