NRMCA's periodic reporting of ready mix production across the U.S. prompted The Concrete Producer magazine to conduct a poll on how producers are faring this year. Editor Tom Bagsarian would like your input and will report the findings at a later date. Read more.
A new stormwater management system made its debut earlier this month in a Pittsburgh neighborhood that's been the site of the some of the city's most severe flooding in recent years. Designed in partnership with the city and Penn State Center: Engaging Pittsburgh, the system uses pervious concrete and a garden, known as a bioswale, to capture and purify water.

Bridge-in-a-backpack? Say what? Well, the University of Maine is researching an "innovative inflatable composite-concrete arch bridge," which it cleverly describes as bridge in a backpack. The technology is more than a decade in the making from the university's Advanced Structures and Composites Center. Researchers there say that the technology can reduce construction time and costs, potentially double the life span of bridges, reduce maintenance costs and significantly reduce the carbon footprint of bridge construction.

A bit of recent economic good news came from the Lone Star State with a report stating that the value of all Texas home sales reached $40 billion in 2011, a figure that is directly in line with 2004 sales. An economist who studied the data said it showed a housing recovery in Texas. Home inventory levels in Texas are down to six months, compared to 6.5 months or slightly higher during the real estate downturn. As inventory levels decline, prices recover and grow higher.

In a ceremony on Wednesday, July 11, Washington, DC, Mayor Vincent C. Gray celebrated completion of the District’s first "green" alleys. The Green Alley Pilot is part of the mayor’s Sustainable DC initiative to make the District the nation’s greenest, healthiest, most livable city. The alley project — a partnership between the District Department of Transportation (DDOT) and the District Department of the Environment (DDOE) — is aimed at reducing the quantity and improving the quality of stormwater runoff within the District’s right-of-way.

"Improving the health of our rivers and streams starts in our neighborhoods with creative solutions like these green alleys," Gray said. Many alleys include a significant amount of impervious surface, but most do not have stormwater controls (such as water quality catch basins or grate inlets). To mitigate this, green alleys use sustainable design and Low Impact Development (LID) techniques that reduce the amount of stormwater and pollutants entering the sewer system, streams and rivers by increasing water filtration and treatment on site.

Three initial Green Alley Project sites are included in DDOT’s pilot program. DDOT constructed its pilot green alleys by replacing gravel, impervious concrete, or asphalt surfaces with pervious concrete. NRMCA Senior National Resources Director Phil Kresge worked with Neil Weinstein of the Low Impact Development Center, to assist in pervious concrete design and specification. Additionally, Kresge provided pervious concrete training to DDOT personnel.

With the first alleys now completed, DDOT is monitoring the three sites to determine the effectiveness and durability of the materials. DDOT will also be constructing a fourth green alley later this summer and has eight additional alley locations in under design. The project is funded through a combination of local dollars and funding received from the American Recovery and Reinvestment Act of 2009 through the U.S. Environmental Protection Agency. The total cost for the first four alleys is $1.2 million.

The picture here taken by NRMCA Senior National Resource Director Vance Pool shows a new Walgreens under construction in League City, TX.  "Tilt up construction is nothing new, but surprisingly many parts of the U.S. have not developed a market," Pool said. "Most think it is only economically viable for warehouses and that it is ugly. There are many retail centers in Texas which have ornamental details rivaling the best Venice, Italy, has to offer at a fraction of other material costs."

"With advantages on first cost and resilience in tornado and hurricane prone areas, it is amazing that people’s misconceptions have slowed tilt-up construction's growth in so many places," Pool said. "Naysayers argue it can’t be insulated easily, but that argument also holds no water. Many engineers don’t take advantage of the structural properties of concrete and put steel columns just inside the walls, adding cost and reducing competitiveness. With our markets still recovering from the recession, tilt-up construction is a great place to grab market share from competing materials."

If you don’t have a market in your area, partner with a contractor from the Tilt-Up Concrete Association. For more information, you may also contact Vance Pool at

ASTM International has published ASTM C595-12, Standard Specification for Blended Hydraulic Cements. The recent revision defines requirements for a new cement type: Type IL, portland-limestone blended cement, which includes more than 5% and up to 15% limestone as an ingredient. This technology has the potential to reduce environmental impact of cement production by about 10% while maintaining performance characteristics concrete producers are familiar with. Similar cements have been used in Europe and other places around the world for several decades and have demonstrated the performance and durability expected in concrete products.

The revision represents the results of several years of cooperative effort by the Joint AASHTO-ASTM Harmonization Task Group, and was endorsed by the Portland Cement Association's (PCA) Product Standards and Technology Committee and Standards Subcommittee. Similar requirements have been approved by AASHTO’s Subcommittee on Materials for AASHTO M240. The update to M240 is scheduled to be published next month.

As part of a broader quality initiative, NRMCA’s Research Engineering and Standards (RES) Committee has been developing brief technical information topics packaged as ‘Technology In Practice’ (TIP) sheets. The NRMCA TIPs are modeled on their popular NRMCA counterpart, the Concrete in Practice (CIP) series. While the CIP series was developed as basic technical topics for the ready mixed industry to use with customers or others involved in concrete construction, the TIP series is written for ready mixed concrete industry personnel to support internal education on general quality control/quality assurance and technical topics.

The TIPs cover topics on standards and testing and are written in simple format with numerical examples when appropriate. The following eight topics are available for the TIP series:
TIP 1 — Quantifying Concrete Quality – provides ideas on identifying items to measure and quantify the impact of a quality goal that positively impacts the company’s bottom line;
TIP 2 — Establishing the Required Average Strength of Concrete – summarizes the general process of establishing the required strength for concrete based on the strength specified in project specifications in accordance with ACI standards;
TIP 3 — Aggregate Sampling for Laboratory Tests – discusses procedures to ensure that samples obtained for quality control tests are representative of the stockpiles or other storage locations from where they are obtained;
TIP 4 — Aggregate Sample Reduction for Laboratory Tests – addresses procedures to properly reduce the size of a larger field sample to a smaller size that is required for laboratory tests; and
TIP 5 — Capping Cylindrical Concrete Specimens with Sulfur Mortars and Unbonded Caps – summarizes the key points in the applicable standards for capping strength specimens and the reasons for these requirements.
(NEW) TIP 6Aggregate Moisture and Making Adjustments to Concrete Mixtures – outlines concepts on aggregate moisture for mixture proportioning and production of concrete;
(NEW) TIP 7Creating and Using Three Point Curves for Laboratory Trial Batches – outlines the process of developing lab trial batch information for mixture submittals; and
(NEW) TIP 8 — Concrete Yield – outlines process for determining yield of concrete and evaluating problems with yield.

Portions of each TIP topic can be viewed and purchased on the NRMCA Web site or contact Jacques Jenkins at or 888-846-7622, ext. 1165.
NRMCA Senior Vice President of Sustainability presented Innovations that Enhance the Sustainable Attributes of Concrete-based Materials at the fourth International Congress on Ceramics held last week in Chicago. A ceramic is defined as an inorganic, nonmetallic solid prepared by the action of heat and subsequent cooling and can have crystalline or partly crystalline structure (such as porcelain or cement) or may be amorphous (such as glass). Attendees at the conference include researchers and practitioners in the field of ceramics and since concrete is made with cement, many are interested in innovative applications of concrete. Lemay was an invited speaker for the infrastructure track at the conference.

Lemay presented advances in products such as pervious concrete, high strength concrete, self-consolidating concrete, flowable fill and roller-compacted concrete along with other conventional concretes that can enhance the sustainability of the built environment. He also discussed recycling efforts of the concrete industry, including cementitious materials, aggregates and water. Efforts to reduce carbon footprint of concrete, including high volume replacement of cement with fly ash and slag cement were discussed. Initiatives such as LEED, the Architecture 2030 Challenge for Products, and other standards that challenge product manufacturers to measure and track carbon footprint and other environmental impacts were explained. The presentation also included a brief review of research being conducted at the MIT Concrete Sustainability Hub designed to quantify and reduce the environmental footprint of concrete.
