Increasing the world population and as a result the human needs, have caused the increase of solid wastes including agricultural, industrial and mining products. The availability of agricultural by-products such as leaf of Phoenix dactilifera, wheat and bamboo stem residuals are increasing in the developing countries. The collection and disposal of these residuals are becoming more difficult and expensive and are therefore left unused as waste materials or simply burned in the fields, thereby creating significant environmental problems. One approach to reduce the environmental pollution is application of waste material in industry which needs researches and experiments. In this research, the use of nano-materials of leaf of Phoenix dactilifera, wheat and bamboo stem residuals as a filler and water stop marerials for joints of irrigation canal was investigated. The experiments include 369 samples of cubical and cylindrical concrete which were stored in different ages (7, 28, 60, 180 days) in two environment conditions (water and solutions of magnesium sulfates). The portions of nano-materials as cement replacement were 0, 20 and 30 percent. The results showed that compressive and tensile strengths of samples containing the different percentage of leaf of Phoenix dactilifera, wheat and bamboo stem residuals are approximately the same up to 180 days ago. However samples incorporating nano-materials of bamboo as cement replacement, (20 percent) showed excellent performance under water environment conditions. Samples incorporating nano-materials leaf of Phoenix dactilifera and bamboo stem residuals as cement replacement showed excellent performance under sulfate environment conditions. The results showed that the modulus of elasticity containing the different percentage of Phoenix dactilifera and bamboo stem residuals has been decreased.
