Evaluating the Strength Properties and Durability of Rigid Pavements Using Carbon Nanotubes

Road transport is important in people's lives, socially and materially. The progress of a country can be directly related to road transportation. It is very important to have a good procedure for proper passages, and to achieve this goal, they choose rigid concrete procedures that are economic, environmental and safe. In current research adding a nano additive increases the resistance and durability properties so that we can also increase the life of the solid surface, for this purpose, from the tests on the constituent components of the top concrete (aggregate, water, cement) suitable for it from the tables The standard is specified. With the study done on the research and examination of professors, single-layer carbon nanotube material was selected to improve and change the properties of concrete. After adding nanotubes with different ratios (3-5-7 percent of cement weight) to the concrete, the compressive strength test was performed on the control and modified sample and a 20% increase was observed, and the tensile strength improved by 13%. Also, the durability of the procedures increased by 30%, which was very impressive and significant, and showed a 28% reduction in water absorption.
