TAPPI’s Nano Division Presents a One-Hour Webinar on April 17
Monday, April 17, 2017 - 12:00pm - 1:00pm EST
No cost to attend, but you must register.
In this webinar, Professor Youngblood will present a brief overview of cement and its chemistry 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. Learn more.
