SPR-4336: Improvement of Scaling Resistance of Pavement Concrete Using Titanium Dioxide (Tio2) and Other Nano-additives

It is expected that this research will result in development of reliable and relatively inexpensive (considering the small percentages of nanoparticles needed) method of improving the scaling resistance of pavement concretes containing fly ash. Additional benefits may include increased resistance to chemical attack by deicing chemicals (due to expected creation of more impermeable microstructure) and increase in mechanical properties of concrete pavements. If successful, the proposed method of increasing scaling resistance of fly ash concrete will allow for extension of the construction window for usage of fly ash while, at the same time, increasing durability of concrete (by reducing the amount of calcium hydroxide and reducing the permeability).
