Project description

This project has following Objectives: (1) evaluate the effect of nanosilica admixtures on the air-void characteristics of concretes used for construction of bridges and bridge deck overlays, (2) examine the influence of the characteristics of the air-void system on the freeze-thaw resistance of concrete, (3) compare the influence of the concrete production method (lab vs. field) on the durability of concrete, (4) examine, in partnership with INDOT’s Division of Materials & Tests, the effect of non-traditional (microsphere type) air entrainment products on the quality of the air-void system in concretes with nanosilica admixtures.
