In order to control seepage from the dam, various methods are used to reduce water seepage. One of the methods of reducing the permeability of the water according to its material is building cut-off walls and filling them with plastic concrete materials. In this study, it has been tried to study the mixing plan of the plastic concrete in the main body of the Nargesi dam’s cutoff wall and to determine the results of compressive strength and elasticity modulus of 108 panels of cut-off wall in different ages in this project. Due to the individual concreting of each panel from the cutoff wall, the results of the plastic concrete panels at runtime are somewhat different. Due to the sensitivity of the plastic concrete to the dispersion of the results, considering that the cutoff wall should have a seamless function as well as the sensitivity of the concrete over time, it seems necessary to address this issue in an operational project. The results indicate that the growth rate of elastic modulus in a period of time is less than the growth rate of the compressive strength, and in other words, the plasticity of the concrete is changed less over time.
