The effects of utilizing silica fume in Portland cement pervious concrete
… fume in addition to analyzing the results of testing on Portland Cement Pervious Concrete mixtures that also contained silica fume. Testing conducted included a study of the effects of silica fume on cement's rheological properties at various dosage rates ranging from zero to ten percent by …

Development Of A High Strength Laminate Repair System
… scanning calorimetry and dynamic mechanical rheological testing were performed to analyze the curing kinetics of each resin tested. Static double cantilever beam and tension-tension fatigue tests were performed to measure the mechanical performance of each resin. All specimens were prepared …

Single wall carbon nanotubes as viscosity modifiers in polypropylene matrix nanocomposites
… in the polymer matrix before subjecting them to rheological testing. Fluorinated single-walled nanotubes (F-SWNTs) played a critical part in evaluating how functionalizations could affect the viscosity of the polymer melt. Fibers made from weight percents ranging from 2.5wt% to 10wt% of F-SWNTs …

Sustainable 3D Concrete Printing for Eco-conscious Construction: Recycled Aggregates and Low-carbon Binders
… of which eleven were fully characterised through rheological testing, 3D printing and mechanical testing. The research demonstrates that significant reductions in Portland cement can be achieved through the use of supplementary cementitious materials (SCMs) such as fly ash, silica fume, slag, and …

Process-Structure-Property Relationships of Cellulose Derivative/Thermoplastic Urethane Polymer Composites
… filler interactions dictate thermal stability, rheological behavior, mechanical performance, and water-responsive properties. Through a series of three integrated studies, the evolution of these composites from solvent-cast films to fully extrudable, AM-compatible filaments is established. In …

Micro- and macro-rheological studies of the structure and association dynamics of biopolymer gels
… In this thesis, we use a combination of rheological testing and constitutive modeling to study this relationship between microstructure and mechanical properties in three biologically-relevant complex fluid systems. First, we explore the network structure and association dynamics of …
