    High performance concrete (HPC) offers several advantages over normal-strength concrete, namely, high mechanical strength
    and high durability. Therefore, HPC allows for concrete structures with less steel reinforcement and a longer service life,
    both of which are crucial issues in the eco-efficiency of construction materials. Nevertheless international publications on
    the field of concrete containing nanoparticles are scarce when compared to Portland cement concrete (around 1\%) of the
    total international publications. HPC nanoparticle-based publications are even scarcer. This article presents the results of
    an experimental investigation on the mechanical properties and durability of HPC based on nano-TiO2 and fly ash. The
    durability performance was assessed by means of water absorption by immersion, water absorption by capillarity, ultrasonic
    pulse velocity, electric resistivity, chloride diffusion and resistance to sulphuric acid attack. The results show that the concretes
    containing an increased content of nano-TiO2 show decreased durability performance. The results also show that concrete
    with 1\% nano-TiO2 and 30\% fly ash as Portland cement replacement show a high mechanical strength (C55/C67) and a high
    durability. However, it should be noted that the cost of nano-TiO2 is responsible for a severe increase in the cost of concrete
    mixtures.
