One of the common linings in water conveyance canals is concrete. Due to the fact that the average life of concrete linings is about 40 years, it is one of the best linings. Extensive worldwide research is currently focused on the types of pozzolans as well as the durability of concrete made from synthetic pozzolans. For this reason, this research was conducted with the aim of using pozzolans produced from date palm leaves at the nanoscale and some mechanical properties of concrete were investigated. The studied properties are: compressive strength, tensile strength, elasticity and durability of concrete containing date palm leaf pozzolans in sulfated environment. The results of this study showed that in concrete made with pozzolan at low ages, the amount of compressive strength of concrete is less than control concrete and at older ages over time, the amount of compressive and tensile strength increased. The values of modulus of elasticity in the treatments containing pozzolan were significantly reduced compared to the control concrete. The performance of treatments containing palm leaf nanoparticles in sulfated environment was better than control concrete. Finally, according to the cases studied, it can be concluded that the use of 20 percent pozzolanic palm nanoparticles with a strain ratio of 318 compared to control concrete, has significant deformation values, so the use of this makes the material as a filler possible for expansion and contraction joints.
