Previous studies have shown that cement production leads to the loss of natural resources such as limestone and fossil fuels and to the environmental pollution by greenhouse gas emissions, such as carbon dioxide. Therefore, durability of concrete structures is of particular importance. Using additives and also replacing conventional materials applied in concrete with new materials, has always been of great consideration. Nanomaterials are one of the new series of materials which have improved the mechanical and durability properties of concrete. In the present research, in order to evaluate the effect of freeze-thaw durability of concrete containing different percentages of nanocarbon cement structures on its flexural strength, weight loss test and three-point bending strength test were conducted. These nanostructures have been grown on Portland cement type II by chemical vapor deposition method. The results indicated that samples with 10% nanocarbon cement structures have led to the best performance of concrete pavement exposed to freeze-thaw cycles. Using of nanocarbon cement structures reduced weight loss and loss of flexural strength in the concrete pavements, and thereby improved the durability of concrete pavements exposed to freeze-thaw cycles.
