High quality and durable cement based materials are critical for the development of our Nation=s infrastructure. My research program contributes by focusing on topics that lie at the interface between structural engineering and materials science of concrete. My research interests arise from observations that our most thorny problems in the field performance of structures are often associated with fundamental material behavior. By addressing problems relevant to structural and pavement engineers, for example, with the tools of materials science, I have made contributions that are scientifically rigorous and relevant for improving the design-durablility of our infrastructure.
I have developed a vigorous research program to investigate the microstructure and properties of cement- based materials. Funding success is one sign that my research activities are significant and relevant to the civil engineering community. My research has attracted substantial research support from Federal and State Agencies and industry; including the Federal Aviation Administration, the Illinois Department of Transportation, Portland Cement Association and several corporations. I have been recognized for research excellence by being named Narbey Khachaturian Faculty Scholar in the Department of Civil and Environmental Engineering (1998), by receiving the American Concrete Institute Wason Medal in 2003, and the UIUC Xerox Award for Faculty Research in 2004. In recognition of my research contributions, I was named Fellow of the American Concrete Institute in 2002.
I have increasingly influenced the agenda of prominent research organizations. In 2003, I was named Associate Director for the Center for Advanced Cement Based Materials (ACBM), an industry supported center that originated as an NSF Science and Technology Center in 1989. In recent months, I played a lead role to develop the Center for Airport Technology X a new center that builds upon the current FAA Center of Excellence for Airport Technology through joint sponsorship by new organizations.
The following paragraphs describe my research accomplishments and goals. My research projects define four related themes: 1) Behavior of concrete at early ages; 2) The modeling drying shrinkage stress; 3) Fiber reinforcement of concrete; and 4) Bond mechanisms of masonry and repair materials.
Behavior of concrete at early ages:
Concrete undergoes slight changes in volume within the first days after casting that can cause high stresses and even cracking of restrained components. The volume change occurs because hydration products are less voluminous than the unhydrated cement and water. There also exists a significant role of external drying and thermal contraction. We developed a unique laboratory experiment to measure restrained shrinkage stress that enables separation of drying shrinkage from creep behavior. Insights from our experiments (and those of other investigators) led to a greater understanding of early age cracking in slabs and prevention through material design.
Modeling of shrinkage stress from drying in porous materials:
Water plays a critical role in many aspects of concrete material behavior. Consequently, I have been drawn to study the nature of water in partially saturated pore structures. We developed inexpensive yet accurate embedded sensor technology to measure relative humidity (RH) inside porous materials. Our model uses measured RH as a fundamental parameter to describe the state of Aunderpressure@ in the pore solution that drives drying stresses. When the solid skeleton of microstructure is placed under a state of tension, the material not only elastically deforms but undergoes creep which causes permanent, unrecoverable deformation. Our model predicts the gradient of stress through the cross section of concrete under drying conditions and the tendency for cracking. This work is now receiving attention from other research groups, and we have broadly shared the details of our device via publications and a website to transfer the technology to other users.
Fibers added to concrete often provide dramatic improvements in resistance to cracking and in the fracture energy (toughness). One of the most vulnerable time periods for concrete occurs during the first days after placement when tensile strength is low and thermal and shrinkage stresses may be high. We investigated the use of fibers to reinforce normal concrete slabs, but we have also examined very high performance, specialty materials called Densified with Small Particles (DSP) and Macro Defect Free (MDF) materials. DSP and MDF are made with special processing steps to achieve very low porosity, resulting in extremely strong, but brittle materials. Our work has demonstrated that the machinability of DSP and MDF is improved by addition of the fibers.
Bond mechanisms of masonry and repair materials:
Fundamental issues of interest include: the role of surface roughness of the substrate; water transport between the fresh mortar and the dry concrete or clay brick substrate; the adhesive capacity of hydration products that develop in the near surface pore structure of the substrate; the quasi brittle fracture behavior that arises from masonry and repair bond. One unique accomplishment in this work employed x ray absorption to monitor water movement in masonry materials. This real time measurement supported our development of a model that uses fundamental physical laws to predict the rate of water transfer from a suspension of packed particles (i.e. fresh mortar) into a porous medium (i.e. masonry brick). Our model predicts the influence of mortar design parameters including water content, particle size distribution, and the influence of admixtures.
Impact and Future Direction:
My research is positioned at the interface between civil engineering and materials science, and it impacts both sides of that interface. My work has Adownstream@ impact on transportation engineers (e.g. at the Illinois Department of Transportation) who have used our research to specify better materials for construction of bridge decks, on WR Grace engineers who have used our research to design new fiber-reinforced concrete systems, and on engineers at the Federal Aviation Administration faced with curling on very large airport taxings and runways. My work also creates Aupstream@ impact in its scientific contribution to fracture mechanics modeling, pore structure characterization, and understanding the stresses in porous materials under unsaturated conditions.
Research should have a strong impact on service and teaching. For example, my research has a direct impact on committees at the American Concrete Institute that benefit from my expertise in shrinkage and creep, fiber reinforced concrete, and materials science of concrete. This research also plays a prominent role in my materials courses at UIUC and in shortcourses outside of UIUC.
My future work will continue to focus on solving problems with concrete materials and on building a better, fundamental understanding of the microstructure on material properties. My current work with embedded sensor technology is among the more exciting research thrusts, and will attract sustained, external support. Leadership roles with the Center for Advanced Cement Based Materials and the Center for Airport Technologies provide me with an opportunity to build teams of researchers to address more interdisciplinary problems.
I am attracted to important material issues relevant to the field of concrete construction. My four theme areas define a realistic approach for research on construction materials. The design and performance of novel experiments, focused on areas of widely identified need, have been a successful strategy for building a nationally visible research program at UIUC.
