Description:About the Seminar:\n\nConcrete is valued in architecture\, note
 d for its durability\, longevity\, and mechanical properties. However\, th
 ese properties can be improved even further by the addition of small addit
 ives that can promote a denser\, stronger composite. Stein and Stevels fir
 st added nanoparticles to make concrete composites in 1964 by introducing 
 nano-SiO2 to simplified cement. This exploration led to an entire field o
 f nano-concrete composites which proved to enhance the physical properties
  of the material through increased mechanical strength and durability. Thi
 s is believed to come from the increased density from nanomaterials packin
 g into the matrix and the reactivity of the high surface area on the concr
 ete hydration reaction. While these composites have been studied for 60 ye
 ars\, the significance of the effect of nanoparticle surfaces on concrete 
 properties from a chemistry perspective has been minimally studied and con
 tributes to some of the challenges seen in the field. By using colloidal s
 ynthesis methods\, surface chemistry can allow for improvement of composit
 e processing and material design of desired material properties 4:00 pm
