ACI President David Lange Scheduled to Speak in Lincoln
"Emerging Materials for Civil Infrastructure" October 10, 2018
Guest Speaker:
Prof. David A. Lange, University of Illinois at Urbana-Champaign
and President, American Concrete Institute
DETAILS:
 Advances in materials with novel properties are making possible new applications for cement and concrete. The surge of interest in 3D printing of concrete structures requires a new look at flowable cement-based materials that exhibit green strength sufficient to hold shape while still creating effective bond with previously placed layers. Recycled materials are emphasized as part of sustainable construction practices, and we are learning how to use the fine particle fraction that is usually discarded. The recycled fine particles can be used for controlled low strength materials. New foamed materials make possible extremely lightweight building products, and also open possibilities for engineered materials for absorbing impact. We have studied microstructure of foamed materials using x-ray computed tomography and new mechanical tests. We are also using advanced computer modeling to capture the crushing behavior of foams as well as the flow behavior of 3D printable cement-based materials. These advances are examples of the many new opportunities for concrete materials that will open the door to new applications and construction methods.
