NRMCA Vice President, Local Paving, Don A. Clem recently teamed with Jamie Johnson, a pavement engineer with the Colorado/Wyoming chapter of the American Concrete Pavement Association, to discuss with engineers from Aurora, CO, the city's newly adopted roadway design and construction specifications. The specifications included provisions which required both new streets and intersections to be constructed with asphalt pavement. The engineers indicated that the provisions were unintended and agreed to issue an errata removing these requirements, allowing concrete pavement to be specified in the city.

NRMCA and ACPA CO/ WY also offered to assist Aurora city officials with some concrete pavement design issues, construction details and assistance on a large upcoming concrete repair project. Other upcoming roadway projects where concrete pavement might be a good option were also discussed. With a population of over 350,000, Aurora is the third largest city in Colorado, and is expected to continue to grow.

The goal of the DIL program is to broaden participants’ understanding of the ready mixed concrete industry at a national and strategic level while also giving them the opportunity to work on a diverse team with members from across the country. This peer-centric program, with its accompanying industry mentorship, encourages participants to make lifelong, career friends as they gain insight into a specific industry-specific, national challenge. The collective group will start its work in the next month, meet face to face during NRMCA’s ConcreteWorks, September 29-October, in Grapevine, TX, and present its findings at a membership meeting during NRMCA’s annual convention in March 2018. The second year in the program includes a leadership development workshop. Once complete, the DILs are encouraged to fully participate in association committee meetings.

NRMCA in collaboration with Dr. Neal Berke with Tourney Consulting Group has completed a research project titled Evaluation of Chloride Limits for Reinforced Concrete Phase A. The research was conducted at NRMCA and Tourney laboratories. The purpose of this phase of the research was to establish a relationship between the calculated total (initial) chloride content and the measured water-soluble chloride content in hardened concrete at a later age. The ACI 318 Building Code prescribes limits on water-soluble chlorides for concrete.

Concrete mixtures evaluated in this study included Type II and Type V portland cement, Class C and Class F fly ash, silica fume and slag cement. Mixtures with varying water-cementitious materials ratio were evaluated. The initial chloride content of the mixtures was varied between the background amount up to 2% by weight of cementitious materials by adding controlled amounts of calcium chloride. The initial chloride content was verified by measuring the acid soluble chloride content in accordance with ASTM C1152. The water-soluble chlorides were measured at an age between 28 and 42 days in accordance with ASTM C1218, as required by ACI 318-14.

In all cases, the measured water-soluble chlorides were less than the initial calculated chloride content and measured acid-soluble chloride content. The estimated initial chloride content determined by calculation of the chloride content of concrete materials and the concrete mixture proportions can be used to ensure that proposed mixtures will conform to the chloride limits stated in the Building Code and specifications. This permits the concrete producer to make adjustments to the mixture before the submittal rather than dealing with measured test results during the project. The research study supports a code change proposal to ACI 318 to permit the calculated total chloride to document conformance with the chloride limits in the Code.

This research work was funded by the RMC Research & Education Foundation and the ACI Concrete Foundation.

The next NRMCA Concrete Durability Course has been confirmed for September 18-20, 2017, at the AGC of Utah headquarters in Salt Lake City. The course is taught by Michael Thomas, University of New Brunswick; Kevin Folliard, University of Texas at Austin and NRMCA Engineering Staff. The course provides a fundamental understanding of the nature of cement and concrete as they relate to durability of concrete. Topics will cover cracking, alkali aggregate reactions, sulfate attack, corrosion of reinforcing steel, freeze-thaw durability and other aspects. A group exercise will be facilitated to familiarize attendees with the ConcreteWorks software used for mass concrete and service life prediction. The course also discusses the durability provisions in the Building Code - ACI 318-14 and how specifications can be structured to address durability. Comprehensive reference material is provided as course notes that is an excellent resource to concrete producers and associated technical personnel.
Those with the NRMCA Level 3 Certification obtain the NRMCA Concrete Technologist Level 4 Certification when passing the exam offered with the course. It is not essential to have attended the NRMCA Technical Short Course to attend the Durability Course. The course provides required learning units toward the technical track of the NRMCA STEPS certification program. Persons interested in attending this course are encouraged to register as soon as possible.

Two thousand years ago, Roman builders constructed vast sea walls and harbor piers. The concrete they used outlasted the empire — and still holds lessons for modern engineers, scientists say. A bunch of half-sunken structures off the Italian coast might sound less impressive than a gladiatorial colosseum. But underwater, the marvel is in the material. The harbor concrete, a mixture of volcanic ash and quicklime, has withstood the sea for two millennia and counting. What's more, it is stronger than when it was first mixed.

The joints had been fixed and fresh asphalt laid over 40-year-old concrete on Interstate 94 between downtown Minneapolis and Brooklyn Center. But before traffic even started to roll over the new multimillion-dollar freeway, the pavement buckled in five places from the 90-degree June heat, leading to higher costs and more delays. The incident highlights a wrenching debate that is playing out among state officials trying to stretch limited transportation money to fix or replace as much roadway as possible. In Minnesota and in many other states, transportation funding has lagged as road conditions have deteriorated.

Houses can be made of wood, as they were in the past – or of concrete, as they are today. To build for tomorrow, the two building methods are being combined: these hybrid structures, which contain both wood and concrete elements, are becoming increasingly popular in contemporary architecture.
