    Upcoming Webinar - NEx Webinar Series: Guidelines for Using FRP Dowels in Concrete Pavement

    Fiber-reinforced polymer (FRP) dowels are lightweight, noncorroding, and appear to be promising alternatives to conventional metal dowel bars. Much research on FRP dowel materials, design, and behavior has been conducted since the 1980s, including evaluation of the performance of several demonstration projects after 20 or more years of service. This research and long-term field experience have contributed to recent interest in the increased use of FRP dowels in highway pavements. This webinar will describe current thinking concerning physical and mechanical requirements (material properties) for FRP dowels, and concepts for designing load transfer systems using FRP dowels to provide joint behavior and pavement performance similar to those of pavements with solid metal dowels. The construction and performance of selected FRP-dowelled pavement construction projects will be presented, and newer specifications for using FRP dowels will be described. This webinarwill be presented by Mark Snyyder and Peter Taylor on August 21 from 1:00-2:00 PM EDT.

    The topic of relevance is a core aspect of ACI's strategic plan. Actually, the first task assigned to new ACI Board of Direction members is to read Race for Relevance by Harrison Coerver and Mary Byers. Questions about relevance impact all standards development organizations (SDOs) like ACI.

    In a world driven by a superfast technology train, how can SDOs be as impactful tomorrow as they have been in the past? Isn't it easier to find a quick (and free) answer on Google, YouTube, or Wikipedia, rather than purchase and dive into hundreds of pages of codes and standards?

    The new dynamics of unpredictable technology change prompted ACI in 2015 to assign a task group the mission of developing an outlook for ACI in 2030. The result was ACI Vision 2030, which identified the megatrends in the world and our industry and recommended responses and actions ACI should take to maintain its relevance in the future.

    In discussing the current and future roles of ACI, we need to consider data, information, and knowledge and the relationships between them. The following chain from Making Sense of Data and Information (Elsevier, 2007) explains it best:

    Let's apply this to the data, information, and knowledge developed around properties of concrete production and supply. As shown in the table below, data are finite descriptions of the concrete delivered to the project, and information includes the application and the interpretation of the data. Knowledge results from the processing of the information as needed to manage or enhance the project schedule, cost, and quality.

    ACI has been developing consensus-based documents to equip the concrete industry with the tools to structure the data, transform it into useful and reliable information, and finally, and most importantly, model the information to develop consensus and universally trusted knowledge. While data is precise, information can take different shapes or forms, whereas useful knowledge must be based on consensus for it to be a universally accepted agent for improvement. Because of its rigorous consensus-based system, ACI provides a unique platform to build trusted and assured knowledge, something that Internet search engines fall short of guaranteeing.

    Having random information does not necessarily lead to correct knowledge. Knowledge implies deep understanding of data and information, experience in using and developing them, prior research, and continuous validation. This is exactly what our volunteers and staff bring to the industry. And that is how our Institute brings tremendous value in different critical areas of concrete construction, whether that value is life safety, durability, or constructibility.

    While this noble mission will surely survive the test of time, as validated by ACI Vision 2030, it may still not address tomorrow's requirements. The industry also needs quick access, smart and customized information, and direct answers—not just consensus-based documents, as valuable as they will always be.

    ACI has over 200,000 Facebook followers and around 60,000 members on its LinkedIn page, with most of our 21,000 active members participating. There are huge numbers of people on ACI social media channels who are not only seeking information, but also yearning to enhance their knowledge of concrete and its applications.

    ACI is therefore evolving from disseminating consensus-based knowledge to empowering a global concrete community, able to successfully address the challenges of concrete construction. Assuming this new responsibility will maintain ACI as one of the most relevant associations on concrete and its uses.

    News Detail


  • 05 Jul 2017 8:21 AM | Beth Britt (Administrator)

    ACI is incorrectly perceived sometimes as a U.S.-focused association, or more generally as a North American Institute. It is very true that the American Concrete Institute, as the name and the history suggest, has strong roots in the United States and North America, but it is equally true that ACI is a global organization.

    The facts and numbers corroborate this.

    The ACI 318 Building Code is adopted, either directly or as a main reference, in the national code of more than 30 countries, representing around 45% of the world gross domestic product (GDP) and 30% of the world population.

    Our Institute has around 21,000 members, including corporate and sustaining members. Out of these, 30% are from outside the United States, and ACI also has just over 3600 international student members in more than 30 countries.

    ACI has a total of 43 international chapters in 31 countries. In parallel, ACI has 39 international agreements with regional partners in six continents.

    In addition to ACI chapters involved in certification, the Institute has 17 international local sponsoring groups organizing ACI certification programs in more than 20 countries. ACI certification has been recognized as an essential tool to assess the competence of concrete professionals, even in some countries that adopt different standards than ACI and ASTM International.

    All these numbers clearly underline the global influence of ACI. Still, given the pace of concrete construction around the world, especially in Asia, it is fair to say that the Institute must be even more present internationally to fulfill its mission of disseminating knowledge globally and achieve the vision where "everyone has the knowledge needed to use concrete effectively to meet the demands of a changing world."

    How? There are several initiatives currently underway at ACI aiming to increase our global clout. I am confident we will start seeing some results very soon. At the ACI Concrete Convention and Exposition – Spring 2017 in Detroit, I cited three targets for 2021 that should reflect increased international engagement for ACI in the next 5 years. They are called the 100,000, 10,000, and 1000 milestones.

    By the end of 2021, ACI will have 100,000 student members around the world. Students and Young Professionals define the very future of the Institute. Being able to attract them is an insurance for ACI relevance. Not all civil engineering students end up in concrete construction but for those who will, ACI must be the preferred platform for professional networking and career development. We will work with ACI chapters around the world to encourage local and regional student competitions and develop a career support center for young professionals.

    Secondly, by 2021, 10,000 projects around the world will be linked to the ACI Manual of Concrete Practice (MCP), the Institute's largest knowledge source. This resource is still so untapped nationally and internationally. We will find innovative ways to communicate to the world the technical, practical, and commercial value of the tremendous intellectual capital our volunteers bring to ACI.

    The MCP is invaluable for every concrete construction project. The wealth of information that it encompasses can undoubtedly help address the challenges and opportunities concrete presents around the world. We will design different tools and means to make the ACI MCP accessible to projects, with hands-on guidance provided by ACI staff and intelligent workflow solutions available in ACI publications.

    Finally, the third goal is that by the end of 2021, ACI will process 1000 international certification exams every month. This is around 10 times what the Institute does today. By recognizing the local standards of different nations and regions in ACI certification programs, ACI will become the global enabler for assessing the competence of technicians, inspectors, quality control managers, and other levels of concrete practitioners and professionals.

    These are hard numbers, in every sense of the word. But with the energy and dedication of ACI staff and volunteers, these milestones can become very achievable targets in 5 years.

    Hot Weather Concreting—Methods for Success

    04/28/2017


    Injection of liquid nitrogen into concrete truck

    As a global leader in advancing concrete knowledge, ACI’s goal is to keep concrete industry professionals up to date with the latest information.

    For example, here’s a recent exchange from ACI’s Q&A section:

    Q. “What are the ACI building code requirements for placing concrete in a tropical climate? Some people in our office say we should specify a maximum permissible concrete temperature of 90 ºF (32 ºC). Others say a temperature higher than 90 ºF (32 ºC) is allowable if the concrete contains a set-retarding admixture.”

    A. ACI 301-16 “Specifications for Structural Concrete” and ACI 305.1-14 “Specification for Hot Weather Concreting” limit the maximum concrete temperature to 95 °F (35 ºC) at the time of discharge. This limit is for general types of hot weather construction such as pavements, bridges, and buildings, not mass concrete.

    Hot weather concreting is defined by ACI as “one or a combination of the following conditions that tends to impair the quality of freshly mixed or hardened concrete by accelerating the rate of moisture loss and rate of cement hydration, or otherwise causing detrimental results: high ambient temperature; high concrete temperature; low relative humidity; and high wind speed.

    Various adverse effects on the properties and serviceability of concrete are brought on by hot weather. Just one of those is the effect on strength—concrete mixed, placed, and cured at elevated temperatures normally develops higher early strengths than concrete produced and cured at lower temperatures.
