The effects of nano – Al2O3 particles replacement on abrasion resistance property of ultra high performance concrete

Abstract

— In the present investigation, the abrasion resistance of ultra high performance concrete (UHPC) containing nano Al 2 O 3 particles have been investigated at an age of 28 th , 56 th and 90 th days. The cement was partially replaced by 0.5%, 1%, 1.5%, 2% and 3% nano Al 2 O 3 . The results were revealed that increasing the nano Al 2 O 3 particles have found to be reducing the loss in mass and average loss in thickness of ultra high performance concrete, due to better packing of nano Al 2 O 3 was reduced the porosity.
