Durability Properties of High-Performance Concrete Incorporating Nano-TiO2 and Fly Ash

Mohseni, E., Ranjbar, M. M. & Tsavdaridis, K. D. ORCID: 0000-0001-8349-3979 (2015). Durability Properties of High-Performance Concrete Incorporating Nano-TiO2 and Fly Ash. American Journal of Engineering and Applied Sciences, 8(4), pp. 519-526. doi: 10.3844/ajeassp.2015.519.526


High Performance Concrete (HPC) is a concrete that is designed to provide high strength and excellent durability. This paper investigates the hardened properties of HPC incorporating nano-TiO2(NT) and Fly Ash (FA). TiO2nanoparticles at the rates of 1, 2 and 3% and low-calcium fly ash at the rate of 30% of the binder by weight were considered. Compressive strength was conducted at the ages of 7 days as an early age and 28 days as the standard age to determine the mechanical properties of HPC incorporating FA and NT. The durability performance was assessed by means of water absorption by capillarity, ultrasonic pulse velocity, chloride diffusion and resistance to sulphuric acid attack. The results indicated that the concretes containing NT increased content show improved durability performance. Moreover, the results showed significant improvement in the properties of the samples incorporating the replacement of cement with a combination of 1% TiO2nanoparticles and 30% FA.
