Concrete Pavement Containing High Volumes of Recycled Materials, Jeffery S. Volz
Presented by: Dr. Jeffery Volz Associate Professor, the University of Oklahoma
Concrete production uses a considerable amount of non-renewable natural resources and generates a significant amount of greenhouse gases. To obtain a more sustainable solution requires examining the two main components of concrete – aggregates and cement. Recycling concrete as aggregate for new concrete reduces construction waste, diverts material from already over-burdened landfills, and lowers demand for virgin aggregate. Using supplementary cementitious materials – such as fly ash, blast furnace slag, and glass powder – also diverts material from landfills and reduces the carbon footprint of concrete.
To date, no studies have examined combining high volumes of recycled concrete aggregate and supplementary cementitious materials in concrete. The main objective of this research study was to produce concrete for conventional pavement construction that incorporates at least 50% recycled materials (both recycled concrete aggregate and supplementary cementitious materials) without compromising performance or service life.
The primary deliverable from this research project will be a set of guidelines for material selection and mixture optimization for using high volumes of recycled materials in concrete pavement. These guidelines will be used to create either prescriptive- or performance-based specifications for incorporation into standard specifications or job-specific provisions.

Presented by: Dr. Raissa Ferron Assistant Professor, University of Texas at Austin
Concrete materials will respond to their environment. At high temperatures, concrete expands. In a low relative humidity environment, concrete shrinks. Thus, the key is not to create a concrete that will react to different types of stresses; that happens naturally. Rather, the true challenge is to engineer a concrete’s response to a stimulus to be one that is desired (aka “smart”), and even better, the concrete’s response can be controlled to achieve a targeted outcome. This presentation will present an overview of research conducted on improving the performance of concrete by using a self-adaptive material approach. Topics to be discussed include self-healing materials and set-on-demand materials.

The Future of Concrete may be in its past, Maria Juenger
Presented by: Dr. Maria Juenger Professor of Civil Engineering The University of Texas at Austin
The concrete industry is under increasing pressure to reduce the energy used in production of portland cement and the associated greenhouse gas emissions. There are several possible ways to address this challenge, but the most straightforward is to minimize the amount of portland cement used by substituting other materials to make concrete binders. We can learn a lot from the Romans, who made strong, durable concrete without any portland cement at all (though not without greenhouse gas emissions!). We are entering a natural pozzolan renaissance, where the industry is searching far and wide for alternative cementitious materials, including those that mimic the Roman pozzolana. This presentation will address current research on alternative concrete binders, including the characteristics and performance of North American natural pozzolans.

Presented by: Antonio Nanni Inaugural Senior Scholar, Professor and Chair, Department of Civil, Architecture and Environmental Engineering University of Miami, Florida
This webinar presents a personal perspective on the potential impact of cementitious materials in the construction industry over the next decade. While it is true that today concrete and its derivatives are ubiquitous, their presence and use can only grow as academia and industry address the challenges of sustainability and resilience. The webinar briefly discusses some of the topics that will fuel this growth and can be considered low-hanging fruits. They include: a) new classes of binders complementing portland cement; b) non-corrosive reinforcement resulting in concrete without chloride limits; c) use of saltwater and recycled/alternative aggregates; and, d) brittle matrix composites for repair. Many other cutting-edge technologies such as nano-materials, ultra-high performance concrete, self-healing concrete, engineered cementitious composites and 3-D printing are not discussed as their impact will be most likely felt in the following decades. Advances and deployment of technology will make the concrete industry greener and more conscious of its environmental impact while, at the same time, providing means and methods to extend the useful life of existing concrete structures.

Presented by: RE-CAST Speaker: Dr. Antonio Nanni, University of Miami
- Joint workshop offered with University of Bath
Abstract: Offering the opportunity to economically create structures of almost any shape, reinforced concrete (RC) is the most common construction material throughout the world. Unfortunately, corrosion of the steel reinforcement jeopardises the integrity of concrete structures, which need to be repaired at a very high cost. Over the past two decades, Fibre-reinforced polymers (FRPs) have gained acceptance as the only viable alternative to steel for the reinforcement of concrete. FRP reinforcing bars are currently used in North America for many ordinary application. But they are also arousing significant interest in Europe, where several global activities are taking place to implement the use of FRP reinforcement into design codes. This workshop aims to build a bridge across the ocean to stimulate the communication and exchange of knowledge on the use of composites for civil engineering construction. The event will provide attendees with first-hand experience of FRP-reinforced concrete structures. Attendees will have a chance to assess what they have learnt, and provide feedback on the workshop through an online survey after the event.
Presented by: Dr. Hani Nassif, Ph.D., P.E., FACI Professor, Rutgers University RE-CAST Associate Director Chair of ACI Committee 444 – Structural Health Monitoring (SHM) and Instrumentation
Structural Health Monitoring (SHM) of concrete structures during and after construction, as well as over its service life, has recently become more attractive to owners and consulting engineers. With the introduction of new materials and construction methods, various types of concrete structures are being instrumented with monitoring devices to determine their performance as well as their response to various loading conditions. Among many other objectives, this includes monitoring concrete performance at the serviceability and durability limit states. Emphasis has been placed on assessment of cracking potential, rebar debonding, and evaluation of rebar corrosion.
This webinar presents an overview of an on-going program for the SHM of concrete bridge decks in the State of New Jersey. In addition to various types of sensors to measure serviceability and other long-term deformations, three types of corrosion sensors are instrumented to monitor the corrosion activities in concrete decks; one is the silver-silver chloride electrode and the other two are multi element probe (MEP) corrosion sensors. The silver-silver chloride electrode provides the corrosive potential by measuring the induced voltage around the rebar. The MEP provides multiple readings of chloride ion content, resistivity and linear polarization resistance. Other types of MEPs were also instrumented on bridge decks during reconstruction in late 1990s to monitor the corrosion potential of the bridge decks. Various types of sensors are installed in precast panels during fabrication as well as in-situ cast concrete decks during and after construction. Moreover, a laboratory-based accelerated corrosion testing program is also performed on concrete specimens using various types of rebars including: Epoxy Coated, MMFX, Black, and Stainless steel rebars. Class A and High Performance Concrete (HPC) specimens with various crack widths and depths are also included. This ongoing study is aimed at correlating laboratory-accelerated corrosion results with long-term performance of the steel in concrete bridge decks under field conditions.

Presented by: Dr. Kaan Ozbay Professor of Transportation Engineering New York University
The reconstruction of the nation’s infrastructure should take into consideration the life cycle costs of major projects, including cost of new construction, replacement, maintenance and repair, cost of work zone delays, and various social-economic costs resulting from these activities. Life Cycle Cost Analysis (LCCA) is an effective tool that can assist decision-makers to develop optimum investment strategies by accurately assessing long-term internal and external costs of various types transportation projects while satisfying budget constraints imposed by transportation agencies. Recently, many new innovative concrete based materials and construction techniques have been developed to achieve a more sustainable transportation infrastructure. However, it remains a challenge to reliably estimate costs and technical performance of these new construction technologies / materials due to the very limited field implementation and historical data. This webinar will present a comprehensive implementation framework to quantify the life cycle costs of these conventional and new high performance materials/construction technologies including novel methodologies to link laboratory-measured parameters to actual field performance. A computationally efficient probabilistic quantification methodology is also integrated into the proposed framework to be able to deal with the high level of uncertainty due to the length of analysis period as well as the lack of real-world performance data especially in the case of novel materials. A web-based user-friendly software tool that makes use of the existing network-wide infrastructure data allowing prospective users to perform state-wide LCCA will also be presented. This webinar will be concluded with a review of future work and challenges in the area of network-wide probabilistic LCCA with a focus on novel construction materials and technologies in the presence of limited field data.

Bespoke FRP Reinforcement for Optimized Concrete Structures, Saverio Spadea
Presented by: Dr. Saverio Spadea Research Fellow University of Bath (UK), Visiting Fulbright Scholar University of Miami, College of Engineering Department of Civil, Arch. and Envoromental Engineering
With the goal of achieving sustainable design, being able to combine optimized geometries with durable construction materials is a major challenge for civil engineering. New research at the University of Bath and the University of Miami aims to solve these problems for the first time by completely replacing internal steel reinforcement in complex optimised concrete structures using a knitted cage made of fibre reinforced polymer (FRP) reinforcement. By fabricating the reinforcement in the desired geometry, it will be possible to provide the required strength exactly where needed, thereby reducing the amount of concrete required to resist internal forces and capitalising on the extraordinary possibilities offered by both concrete and FRP construction materials.

Presented by: Dr. Dimitri Feys, Ph.D. Assistant Professor of Civil Engineering Missouri University of Science and Technology
In this seminar, the recent developments in evaluating pumping behavior of flowable and self-consolidating concrete (SCC) are discussed. First, a brief overview of the underlying physics of concrete pumping is given to introduce the participants to the concepts of friction, flow, hydrodynamic and hydrostatic pressure and the concept of the lubrication layer. Different techniques to assess the lubrication layer properties are then discussed, including tribology and different visualization techniques for the velocity profile. Using tribology, or by combining the rheological properties of the concrete and its constituent mortar and knowing the thickness of the lubrication layer, it is shown that pressure losses during concrete pumping can be successfully predicted. Finally, the influence of different mix design parameters on pumping pressures will be demonstrated.

The Use of Resistivity Testing to Improve Concrete Quality, Lilie Hertell
Presented by: Dr. Julie Hartell Assistant Professor of Civil Engineering Oklahoma State University
The physical and chemical nature of concrete makes it particularly sensitive to electrical conductivity. Recently, investigations have demonstrated that electrical methods, such as the surface resistivity and bulk resistivity methods, are cost effective and accurate means for assessing the durability performance of a concrete mixture. The latter was established through comparative relationship analysis with the standard method of testing ionic conductivity, the rapid chloride permeability test (RCPT). Many procedures and recommendations have been published which led to the developments of new AASHTO and ASTM standards. And, since their introduction, resistivity has been used in the industry for the past decade as a viable means to assess the quality of concrete mixtures with respect to durability performance.
Moreover, resistivity properties of a concrete mixture at a specific age may provide insight on its physical and chemical properties. This principle is currently being investigated at Oklahoma State University to determine whether the method can be utilized to discern undesirable mixture variations. In this case, resistivity testing could be used to improve the current process of concrete mixture approval and site acceptance. The presentation will address the operating concepts and theory behind the testing method; along with a comprehensive discussion on the procedures, result interpretation, application and limitations.
Bio: Dr. Hartell is part of the Structures and Materials Group housed in the School of Civil and Environmental Engineering at Oklahoma State University. Her current research interests are based on advancing our understanding of the behavior of cementitious concrete material through the improvement of testing methods, both destructive and non-destructive, to properly assess its performance in service. She is currently investigating how chemical and physical microstructural disparities may affect the behavior of degraded concrete in order to determine appropriate non-destructive means to quantify the extent of damage under various conditions. Her research interests are reflected in the classroom by teaching the undergraduate Engineering Materials Laboratory course and offering graduate courses on construction materials, concrete testing and monitoring methods, along with infrastructure condition assessment and repair.
Three-Dimensional Study of Concrete Microstructure using X-ray Computed Tomography, David Lange and Tyler Oesch
Presented by: Prof. David Lange University of Illinois, Urbana, IL and Dr. Tyler Oesch U.S. Army EngineerResearch and Development Center, Vicksburg, MS
New technology has made it possible to create three-dimensional images of microstructure to better understand the performance of concrete. X-ray computed tomography (XCT) has been used to study phases — aggregate, paste, air bubbles, porosity and fibers — and discern crack propagation of samples under load. This webinar will feature recent research that explores how XCT can be applied to concrete materials over a range of scale that encompasses small cement grains on the low end to steel fibers and aggregates on the high end. XCT provides unprecedented opportunities: We can interrogate wet samples over time to observe hydration; we can study distribution of entrained air bubbles; we can load samples to study crack propagation and contrast HPC and OPC; we can investigate fiber reinforced materials to appreciate how fibers influence fracture. The research community is only beginning to appreciate how these powerful new techniques will lead to profound new knowledge about concrete materials.
Advances in Concrete Science in the Last 50 Years, Surendra P. Shah
Presented by: Dr. Surendra P. Shah, Ph.D. Walter P. Murphy Professor of Civil Engineering (Emeritus) Director, Center for Advanced Cement Based Materials Northwestern University, Evanston, Illinois
Considerable progress has been made in understanding and improving the performance of concrete. Fifty years ago, the commonly used concrete had a compressive strength of 20 MPa. Today we talk about concrete with a compressive strength of 300 MPa. In addition to high strength and ultra-high strength concrete, we have developed high performance concrete for enhanced durability. Recently, the American Concrete Institute has started new committees on ultra-high performance concretes as well as on nanotechnology. Prof. Shah has been extensively involved in these developments during the last 50 years. He will discuss several mutli-discplinary projects that have led to advances we have made in strength, ductility, fracture properties, fiber reinforced concrete, ultrahigh performance concrete, self consolidating concrete, rheology and sustainability.
Webinars from 2014
Presented by: Dr. Tyler Ley, Ph.D., P.E. Associate Professor and Williams’ Foundation Professor of Civil Engineering Oklahoma State University
This webinar will cover the basics of air entrained concrete and the challenges of providing adequate air void systems with modern concrete mixtures. The presentation will then discuss a new testing device, the Super Air Meter, also called (SAM), that has the ability to measure the air void size distribution in fresh concrete. (www.superairmeter.com) The results from the SAM are shown to correlate with the bubble size distribution determined by the hardened air void analysis in laboratory and field testing. A provisional AASHTO test method has already been prepared and the meter is being used on DOT jobs in 15 different states and in one Canadian province.
Extending the Life of Concrete Structures: FRCM Technology, Antonio Nanni
Presented by: Dr. Antonio Nanni, Ph.D., P.E. Lester and Gwen Fisher Endowed Scholar Professor and Chair, Department of Civil, Architectural & Environmental Engineering University of Miami
This seminar presents the unique material properties of fabric-reinforced cementitious matrix (FRCM) and the provisions for its characterization, design, construction, and inspection. The presentation ends with a brief discussion of case studies on the use of FRCM system repair and strengthening. FRCM systems for repairing and strengthening concrete structures are an alternative to traditional techniques like FRP, steel plate bonding, section enlargement, and external post-tensioning. FRCM is a composite material consisting of one or more layers of cement-based matrix reinforced with dry fibers in the form of open meshor fabric. When adhered to concrete structural members, an FRCM system acts as supplemental, externally bonded reinforcement.
