Nanotechnology has immense potential to result in a new generation of concrete, stronger and more durable, with desired stress-strain behavior and possibly with the whole range of newly introduced properties. Enhanced flexural behavior of the concrete may lead a reduction in the concrete slab thickness used in the construction of concrete pavements. Incorporation of nanomaterials into the matrix to improve concrete mechanical properties has emerged as a promising research field. This paper shows the change in strength behaviour of traditional concrete with substitution of cement with nano titanium dioxide. A nominal mix proportion of required strength is designed with IS 10262:2009 and IS 456:2000. The concrete is mixed with different percentages of titanium dioxide (0%, 0.5%, 1%, 1.5% and 2%) of powder content. In the laboratory, desired concrete was developed and hardened then examined using appropriate testing procedure. Strength behaviour can be analyzed by different tests which require different specimens such as cubes, cylinders and beams for calibrating compressive, split tensile and flexural strength of concrete after 7, 14 and 28 days of curing. After studying the results one percentile replacement of nano titanium dioxide shows maximum strength.
