Abstract
In this study, we studied the effects of Nano-Al2O3 with different contents on the compressive strength of fiber reinforced concrete, for this purpose we used cubic samples of 10cm with four different contents (0, 1, 2 and 4%) of cement by weight. The cement content of the concrete (including 300 kg/m) and fiber (Polypropylene) volume fractions 0.2% of cement by weight were considered. The water to binder (sum of the cement and Nano particles) ratio used for all mixtures is 0.45.The influence of the Nano-Al2O3 on the concrete strength was assessed by measuring the compressive strength at 7 and 28 days. The results showed that the use of Nano-Al2O3 particles produces concrete with improved strength and significantly effected on the compressive strength of the Fiber-reinforced concrete.
