Abstract

Efforts to reduce the cost of irrigation canals while maintaining the characteristics, technical standards, prevent damage to the structure, prevent leakage and losing of water at different stages of water transfer and distribution is of great interest to researchers. One of the solutions is to use pozzolanic materials, which have replaced a part of cement as cheap materials and thus reduce the finished price of cement. One of the most widely used plants in this field is bamboo. For this reason in this study, the amounts of 20 and 30% of bamboo particles in two forms of natural and at the nanoscale were replaced instead of cement and the properties of the resulting concrete in terms of compressive strength, tensile strength, durability in sulfated medium and the modulus of elasticity were examined. Compressive and tensile strength in all treatments increased with increasing age of concrete, but only the treatment containing 20% of bamboo nanoparticles had a similar performance to control concrete. The durability of the treatments made with bamboo pozzolans improved compared to the control treatment and the modulus of elasticity was significantly reduced. Finally, it can be claimed that the treatment containing 20% of bamboo nanoparticles has the potential to be used in the concrete industry, especially as a filler for expansion and contraction joints of concrete water transfer channels. Because it improved the compressive strength, tensile strength, durability and elasticity of concrete to an acceptable level.
