Strength and Drying Shrinkage of Pavement Concrete with Nano-Particles
With the development of national economy in Mainland China, the heavier vehicles and traffic flow have arisen in highway transportation. Concrete pavement has high strength and good durability, and thus is widely used in high-grade highway. Due to the small dimension, nano- materials have many unique physical and chemical properties, and become the focus of material science field. In this thesis, based on the unique characteristics of nano-materials, the ordinary concrete with nano-SiO2 or nano-TiO2 is prepared to research the drying shrinkage of pavement concrete. The test results indicate that the concrete with nano-SiO2 and nano-TiO2 in the amount of 2.0% and 1.0% by weight of binder have the respectively biggest drying shrinkage rate of the same concrete type, which are significantly increased than the ordinary concrete. After 28 days, the dying shrinkage rate of the concrete with nano-TiO2 is 1.6 times to the ordinary concrete.
