High Performance Cement via Cellulose Nanocrystal Addition Webinar

High Performance Cement via Cellulose Nanocrystal Addition Webinar

12:00 -1:00 pm ET
Monday, April 17, 2017

Presenter: Jeffrey P. Youngblood, Purdue University

 

About this event


A brief review of cement and its chemistry will be presented so that current progress on property enhancement of cement by cellulose nanocrystal (CNC) addition will be understood and placed in context.  CNCs are an attractive material class for possible applications in nanocomposites reinforcement, nanomaterials and biomedicine as they have high strength and stiffness, yet are renewable, biodegradable, non-toxic, and cheap.  Previously we showed that CNCs are highly surface active on the cement particles and act to stabilize them in dispersion, thus lowering yield (increasing plasticity), as well as increase strength due to hydration increases.  Here, we will detail efforts to utilize these materials in cementitious composites with special attention paid to the latest results indicating that cement type as well as CNC properties matter. These effects will be presented and explained with a mechanistic view by relying on data from microscopy, rheology, mechanical testing, and other techniques.

Professor Jeffrey P. Youngblood began his collegiate studies at Louisiana State University majoring in Chemistry and Physics.  He started Ph.D. studies at the University of Massachusetts-Amherst and moved on to postdoctoral work at Cornell's Materials Science and Engineering Department where he developed synthetic strategies for the development of coatings that prevent marine biofouling.  In 2003, Professor Youngblood accepted a position in the School of Materials Engineering at Purdue University.  He uses his polymer expertise to investigate nanotechnology, surface science, advanced processing and biomaterials.  Of late, he has been specifically interested in ceramic processing using polymeric methods, advanced composites and fabrication, renewable resins cellulose nanocomposites, and cementitious materials.
