Abstract

The present research work deals about seawater attack of ultra high performance concrete (UHPC) with different percentage of nano Al2O3 powder has been investigated at the age of 30 days, 60 days, 120 days and 180 days exposure period. The cement was partially replaced by nano Al2O3 powder at 0.5 %, 1 %, 1.5 %, 2 %, and 3 % by weight. The change in weight and change in strength loss of UHPC were measured, after sea water attack for the 30 days, 60 days, 120 days and 180 days of the exposure period. The results of this research work clearly showed that nano Al2O3 was optimum replacement improved the resistance against the Seawater attack in UHPC. Because of the smaller size and higher surface area of nano Al2O3 particles play the main role in microstructure and reduced
porosity and water transport properties of UHPC.
