Use of palm leaf nanoparticles in improving the properties of concrete lining of water conveyance canals

This research was conducted 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 a 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; to the point that at 128 days these parameters were approximately 12.35 and 5.8 times higher than that of seven days. The modulus of elasticity values in the treatments containing pozzolan were significantly reduced by nearly 18 percent compared to the control concrete. The performance of treatments containing palm leaf nanoparticles in a 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. Hence, the use of this makes the material as a filler possible for expansion and contraction joints.
