11. IDENTIFYING THE FLUID-TO-SOLID TRANSITION IN CEMENTITIOUS MATERIALS AT EARLY AGES USING ULTRASONIC WAVE VELOCITY AND COMPUTER SIMULATION
Topic: Building Materials
Published: 2/1/2009
Authors: G Sant, Dale P Bentz, W Weiss
Abstract: Assessing the fluid-to-solid transition in cementitious systems at early-ages is crucial for scheduling construction operations, determining when laboratory testing can begin, and for assessing when computer simulations of shrinkage stress should beg ...

12. Interfacial Characterization of Multiple Layer Coatings on Thermoplastic Olefins (TPO)
Topic: Building Materials
Published: 5/30/2008
Authors: Aaron M Forster, Chris A Michaels, Justin Lucas, Li Piin Sung
Abstract: Thermoplastic olefins (TPO) have made significant inroads as polymeric materials for interior and exterior automotive parts. Spray applied chlorinated polyolefins (CPO) are often used to improve paint adhesion to the low surface energy TPO substrate ...

15. Measurement of yield stress for concentrated suspensions using a plate device
Topic: Building Materials
Published: 1/1/2010
Authors: Min-Hong Zhang, Chiara F Ferraris, Huaning Zhu, Vincent Picandet, Max A Peltz, Paul E Stutzman, Daniel De Kee
Abstract: Slump has often been correlated with the yield stress of concrete as defined by the Bingham model. The discussion is still open as to what the yield stress value actually is and how to measure the yield stress of a suspension in general and for a cem ...

16. Measuring Photocatalytic Response of Metal Oxide Fillers in Polymeric Films Using Electron Paramagnetic Resonance Spectroscopy
Topic: Building Materials
Published: 3/18/2009
Authors: Stephanie S Watson, I-Hsiang Tseng
Abstract: Metal oxide fillers, such as titanium dioxide (TiO2), are heavily utilized in polymeric coatings and plastics for opacification, pigmentation, and mechanical enhancement. It is well known that the photoreactivity of TiO2 can contribute to the degrada ...

17. Measuring the Mechanical Properties of Nanocomposites: Potential Complications From the Mullins Effect
Topic: Building Materials
Published: 9/20/2006
Authors: Christopher C White, Donald Lee Hunston
Abstract: Quantification of mechanical properties, such as non-linear viscoelastic behavior, for filled elastomers (model nanocomposites) is complicated by the presence of the Mullins effect. This paper examines the potential complications due to the Mullins ...

18. Mechanisms of Moisture Attack in Adhesive bonds Exposed to High Humidity
Topic: Building Materials
Published: 7/23/2008
Authors: Kar Tean Tan, Christopher C White, Cyril Clerici, Donald Lee Hunston, Bryan D. Vogt, Sushil K Satija, Joshua E. Goldman, Kristen L Steffens
Abstract: Studies have show that certain adhesive joints exhibit a dramatic loss of strength when exposed to humidities above a certain critical value. Although much is know about this effect, questions still exist. This study combines neutron reflectivity e ...

19. PERFORMANCE ASSESSMENTS INSIGHTS ON THE USE OF CEMENTS IN WASTE MANAGEMENT
Topic: Building Materials
Published: 11/7/2010
Authors: David W. Esh, Jacob Philip, Kenneth Alan Snyder
Abstract: The use of cementitious materials has been proposed in a variety of waste management systems because these materials can have a variety of desirable performance characteristics: hydraulic isolation, chemical isolation, structural stability. Cementit ...

20. Reliability-Based Method for Service Life Prediction of Materials
Topic: Building Materials
Published: 9/17/2003
Authors: Christopher C White, Jonathan W. (Jonathan W.) Martin, S F Weber, L Shultz
Abstract: Standard test methods, such as ASTM C719, evaluate sealant performance though threshold test measurements. This method and its derivatives do not offer reliable predictions of in-service performance. This presentation will detail efforts to move aw ...
